Posttranslational regulation of the retinoblastoma gene family member p107 by calpain protease. (1/1302)

The retinoblastoma protein plays a critical role in regulating the G1/S transition. Less is known about the function and regulation of the homologous pocket protein p107. Here we present evidence for the posttranslational regulation of p107 by the Ca2+-activated protease calpain. Three negative growth regulators, the HMG-CoA reductase inhibitor lovastatin, the antimetabolite 5-fluorouracil, and the cyclic nucleotide dibutyryl cAMP were found to induce cell type-specific loss of p107 protein which was reversible by the calpain inhibitor leucyl-leucyl-norleucinal but not by the serine protease inhibitor phenylmethylsulfonylfluoride, caspase inhibitors, or lactacystin, a specific inhibitor of the 26S proteasome. Purified calpain induced Ca2+-dependent p107 degradation in cell lysates. Transient expression of the specific calpain inhibitor calpastatin blocked the loss of p107 protein in lovastatin-treated cells, and the half-life of p107 was markedly lengthened in lovastatian-treated cells stably transfected with a calpastatin expression vector versus cells transfected with vector alone. The data presented here demonstrate down-regulation of p107 protein in response to various antiproliferative signals, and implicate calpain in p107 posttranslational regulation.  (+info)

Metabolism of the antimalarial endoperoxide Ro 42-1611 (arteflene) in the rat: evidence for endoperoxide bioactivation. (2/1302)

Ro 42-1611 (arteflene) is a synthetic endoperoxide antimalarial. The antimalarial activity of endoperoxides is attributed to iron(II)-mediated generation of carbon-centered radicals. An alpha, beta-unsaturated ketone (enone; 4-[2',4' bis(trifluoromethyl)phenyl]-3-buten-2-one), obtained from arteflene by reaction with iron(II), was identified previously as the stable product of a reaction that, by inference, also yields a cyclohexyl radical. The activation of arteflene in vivo has been characterized with particular reference to enone formation. [14C]Arteflene (35 micromol/kg) was given i.v. to anesthetized and cannulated male rats: 42.2 +/- 7.0% (mean +/- S.D., n = 7) of the radiolabel was recovered in bile over 5 h. In the majority of rats, the principal biliary metabolites were 8-hydroxyarteflene glucuronide (14.2 +/- 3. 9% dose, 0-3 h) and the cis and trans isomers of the enone (13.5 +/- 4.6% dose, 0-3 h). In conscious rats, 15.3 +/- 1.6% (mean +/- S.D., n = 8) of the radiolabel was recovered in urine over 24 h. The principal urinary metabolite appeared to be a glycine conjugate of a derivative of the enone. Biliary excretion of the glucuronide, but not of the enones, was inhibited by ketoconazole. 8-Hydroxyarteflene was formed extensively by rat and human liver microsomes but no enone was found. Bioactivation is a major pathway of arteflene's metabolism in the rat. Although the mechanism of in vivo bioactivation is unclear, the reaction is not catalyzed by microsomal cytochrome P-450 enzymes.  (+info)

Ectopic expression of the minimal whiE polyketide synthase generates a library of aromatic polyketides of diverse sizes and shapes. (3/1302)

The single recombinant expressing the Streptomyces coelicolor minimal whiE (spore pigment) polyketide synthase (PKS) is uniquely capable of generating a large array of well more than 30 polyketides, many of which, so far, are novel to this recombinant. The characterized polyketides represent a diverse set of molecules that differ in size (chain length) and shape (cyclization pattern). This combinatorial biosynthetic library is, by far, the largest and most complex of its kind described to date and indicates that the minimal whiE PKS does not independently control polyketide chain length nor dictate the first cyclization event. Rather, the minimal PKS enzyme complex must rely on the stabilizing effects of additional subunits (i.e., the cyclase whiE-ORFVI) to ensure that the chain reaches the full 24 carbons and cyclizes correctly. This dramatic loss of control implies that the growing polyketide chain does not remain enzyme bound, resulting in the spontaneous cyclization of the methyl terminus. Among the six characterized dodecaketides, four different first-ring cyclization regiochemistries are represented, including C7/C12, C8/C13, C10/C15, and C13/C15. The dodecaketide TW93h possesses a unique 2,4-dioxaadamantane ring system and represents a new structural class of polyketides with no related structures isolated from natural or engineered organisms, thus supporting the claim that engineered biosynthesis is capable of producing novel chemotypes.  (+info)

Oxidation of medium-chain acyl-CoA esters by extracts of Aspergillus niger: enzymology and characterization of intermediates by HPLC. (4/1302)

The activities of beta-oxidation enzymes were measured in extracts of glucose- and triolein-grown cells of Aspergillus niger. Growth on triolein stimulated increased enzyme activity, especially for acyl-CoA dehydrogenase. No acyl-CoA oxidase activity was detected. HPLC analysis after incubation of triolein-grown cell extracts with decanoyl-CoA showed that beta-oxidation was limited to one cycle. Octanoyl-CoA accumulated as the decanoyl-CoA was oxidized. Beta-oxidation enzymes in isolated mitochondrial fractions were also studied. The results are discussed in the context of methyl ketone production by fungi.  (+info)

Novel nonsecosteroidal vitamin D mimics exert VDR-modulating activities with less calcium mobilization than 1,25-dihydroxyvitamin D3. (5/1302)

BACKGROUND: The secosteroid 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) acts through the vitamin D receptor (VDR) to elicit many activities that make it a promising drug candidate for the treatment of a number of diseases, including cancer and psoriasis. Clinical use of 1,25(OH)2D3 has been limited by hypercalcemia elicited by pharmacologically effective doses. We hypothesized that structurally distinct, nonsecosteroidal mimics of 1,25(OH)2D3 might have different activity profiles from vitamin D analogs, and set out to discover such compounds by screening small-molecule libraries. RESULTS: A bis-phenyl derivative was found to activate VDR in a transactivation screening assay. Additional related compounds were synthesized that mimicked various activities of 1,25(OH)2D3, including growth inhibition of cancer cells and keratinocytes, as well as induction of leukemic cell differentiation. In contrast to 1, 25(OH)2D3, these synthetic compounds did not demonstrate appreciable binding to serum vitamin D binding protein, a property that is correlated with fewer calcium effects in vivo. Two mimics tested in mice showed greater induction of a VDR target gene with less elevation of serum calcium than 1,25(OH)2D3. CONCLUSIONS: These novel VDR modulators may have potential as therapeutics for cancer, leukemia and psoriasis with less calcium mobilization side effects than are associated with secosteroidal 1,25(OH)2D3 analogs.  (+info)

Lispro or regular insulin for multiple injection therapy in adolescence. Differences in free insulin and glucose levels overnight. (6/1302)

OBJECTIVE: Regular insulin given with the evening meal could contribute to the risk of nocturnal hypoglycemia in adolescents with type 1 diabetes using a multiple injection regimen. To test this hypothesis, we compared glucodynamics and free insulin levels on two separate study nights. RESEARCH DESIGN AND METHODS: A total of 14 adolescents were recruited. On both nights, identical doses of regular insulin or insulin lispro were administered 30 min or 10 min, respectively, before the evening meal, using a double-blind randomized crossover study design. Doses of NPH insulin and carbohydrate content of the evening meal and snack were kept identical. Blood samples were taken every 15 min for blood glucose and every 60 min for free insulin and ketones. RESULTS: After insulin lispro administration, glucose levels were significantly lower between the evening meal and the bedtime snack (analysis of variance [ANOVA] P = 0.02), and four hypoglycemic episodes were recorded. This corresponded to a higher (458 +/- 48 vs. 305 +/- 33 pmol/l, P = 0.02), earlier (64 +/- 4.6 vs. 103 +/- 12 min, P = 0.01), and shorter-lasting (245 +/- 21 vs. 365 +/- 39 min, P = 0.01) insulin peak in contrast to regular insulin. After the bedtime snack, glucose levels increased dramatically during the lispro night and stayed higher, up to 0300 in the morning (ANOVA P = 0.01), corresponding to lower mean insulin levels (146 +/- 20 vs. 184 +/- 27 pmol/l, P = 0.04). No differences were seen in glucose and insulin levels between 0300 and 0800. Four episodes of nocturnal hypoglycemia were documented after the bedtime snack during the regular insulin night, in contrast to one episode after insulin lispro. No differences in ketone levels were observed. CONCLUSIONS: The replacement of regular insulin with insulin lispro may reduce the risk of late hypoglycemia, but redistribution of the evening carbohydrate may be needed to ensure good metabolic control and prevent early postprandial hypoglycemia.  (+info)

A unique urinary constituent, 6-hydroxy-6-methyl-3-heptanone, is a pheromone that accelerates puberty in female mice. (7/1302)

BACKGROUND: Olfactorily mediated puberty acceleration in female mice (measured by an increase in uterine weight) has been observed since the 1960s without the active chemosignal being structurally identified. There are many controversies in the literature as to whether this male-originated pheromone is a volatile substance. We investigated the chemical nature of the urinary fractions that are responsible for the characteristic uterine weight increases. RESULTS: The active pheromone was identified as 5,5-dimethyl-2-ethyltetrahydrofuran-2-ol and/or its open-chain tautomer (6-hydroxy-6-methyl-3-heptanone). A series of cyclic vinyl ethers were isolated from chromatographically active fractions of the urine. Because these compounds did not accelerate puberty, we postulated that these ethers were degradation products of a lactol (5,5-dimethyl-2-ethyltetrahydrofuran-2-ol). The lactol was then detected directly in the mouse urine extract using a silylation agent. Synthetic 6-hydroxy-6-methyl-3-heptanone had strong biological activity, whereas its close structural analogs did not. CONCLUSIONS: The male house mouse excretes into its urine a large quantity of a volatile substance that has a unique lactol/hydroxyketone structure. This substance is capable of binding to the less volatile urinary constituents, such as proteins or peptides, and is active in puberty-acceleration bioassays. The controversies regarding the volatility of the puberty-accelerating pheromones can now be explained by considering a complex of volatile lactol/hydroxyketone and urinary proteins.  (+info)

In vivo effects of ascorbate and glutathione on the uptake of chromium, formation of chromium(V), chromium-DNA binding and 8-hydroxy-2'-deoxyguanosine in liver and kidney of osteogenic disorder shionogi rats following treatment with chromium(VI). (8/1302)

Several previous in vitro studies have indicated that ascorbate and glutathione are the major reductants of Cr(VI) in cells. In order to evaluate the in vivo effects of ascorbate and glutathione on Cr(VI)-induced carcinogenesis, Cr uptake and the formation of Cr(V), Cr-DNA adducts and 8-hydroxy-2'-deoxyguanosine (8-OH-dG) were measured in the liver and kidney of Osteogenic Disorder Shionogi (ODS) rats that lack the ability to synthesize ascorbate. Despite a 10-fold difference in tissue ascorbate levels among different dietary ascorbate groups, the Cr(V) signal intensity, Cr uptake and total Cr-DNA binding were not affected in either organ. Treatment of ODS rats with Cr(VI) (10 mg/kg) had no substantial effect on the levels of ascorbate and glutathione in these tissues. The levels of Cr(V) and Cr-DNA binding were approximately 2-fold higher in the liver than in the kidney, although the levels of total Cr uptake were similar in both tissues. Cr uptake levels were significantly lower in the liver and kidney of ODS rats treated with high levels of ascorbate and a high dose of Cr(VI) (40 mg/kg), suggesting a detoxifying role played by plasma ascorbate. Similarly, modulation of glutathione levels by N-acetyl-L-cysteine, L-buthionine-S, R-sulfoximine or phorone in these animals by up to 2-fold had little or no consistent effect on Cr uptake, Cr-DNA binding, Cr(V) levels or 8-OH-dG formation in either organ. One possible explanation is that reduction of ascorbate and glutathione concentration to <10 and 50%, respectively, of normal in these two organs still provides threshold levels of these two reductants that are in excess of what is needed for significant reductive activation of Cr(VI). Alternatively, it is possible that ascorbate and glutathione do not play a major role in the formation of Cr(V), Cr-DNA binding or 8-OH-dG and that other cellular reductants, such as cysteine or other amino acids, might be more important reductants of Cr(VI) in vivo.  (+info)

Ketones are organic compounds that contain a carbon atom bound to two oxygen atoms and a central carbon atom bonded to two additional carbon groups through single bonds. In the context of human physiology, ketones are primarily produced as byproducts when the body breaks down fat for energy in a process called ketosis.

Specifically, under conditions of low carbohydrate availability or prolonged fasting, the liver converts fatty acids into ketone bodies, which can then be used as an alternative fuel source for the brain and other organs. The three main types of ketones produced in the human body are acetoacetate, beta-hydroxybutyrate, and acetone.

Elevated levels of ketones in the blood, known as ketonemia, can occur in various medical conditions such as diabetes, starvation, alcoholism, and high-fat/low-carbohydrate diets. While moderate levels of ketosis are generally considered safe, severe ketosis can lead to a life-threatening condition called diabetic ketoacidosis (DKA) in people with diabetes.

Ketone bodies, also known as ketones or ketoacids, are organic compounds that are produced by the liver during the metabolism of fats when carbohydrate intake is low. They include acetoacetate (AcAc), beta-hydroxybutyrate (BHB), and acetone. These molecules serve as an alternative energy source for the body, particularly for the brain and heart, when glucose levels are insufficient to meet energy demands.

In a healthy individual, ketone bodies are present in low concentrations; however, during periods of fasting, starvation, or intense physical exertion, ketone production increases significantly. In some pathological conditions like uncontrolled diabetes mellitus, the body may produce excessive amounts of ketones, leading to a dangerous metabolic state called diabetic ketoacidosis (DKA).

Elevated levels of ketone bodies can be detected in blood or urine and are often used as an indicator of metabolic status. Monitoring ketone levels is essential for managing certain medical conditions, such as diabetes, where maintaining optimal ketone concentrations is crucial to prevent complications.

Methyl n-Butyl Ketone, also known as Methyl Amyl Ketone or 2-Hexanone, is an organic compound with the molecular formula C6H12O. It is a colorless liquid with a pungent, fruity odor. It is used as a solvent in various industrial applications, including coatings, cleaning agents, and adhesives.

In a medical context, Methyl n-Butyl Ketone is primarily relevant as a potential occupational hazard. Exposure to this chemical can occur through inhalation, skin contact, or accidental ingestion during its use in industrial settings. Acute exposure to high levels of Methyl n-Butyl Ketone can lead to symptoms such as headache, dizziness, nausea, and respiratory irritation. Chronic exposure has been associated with neurological issues, including memory loss, confusion, and peripheral neuropathy.

It is essential for medical professionals to be aware of the potential health effects of Methyl n-Butyl Ketone, particularly in occupational settings, to ensure appropriate prevention measures are in place and to diagnose and manage potential exposures effectively.

Tosyllysine Chloromethyl Ketone (TLCK) is not a medical term, but a chemical compound used in biochemical research. It is often used as an irreversible inhibitor of serine proteases, a type of enzyme that cuts other proteins. TLCK modifies the active site of these enzymes, rendering them inactive. This property makes it useful in studying the role of specific proteases in various biological processes.

Tosylphenylalanyl Chloromethyl Ketone (TPCK) is not a medical term per se, but it is a chemical compound that has been used in medical research. Here's the definition of this compound:

Tosylphenylalanyl Chloromethyl Ketone is a synthetic chemical compound with the formula C14H12ClNO3S. It is a white crystalline powder that is soluble in organic solvents and has a molecular weight of 307.75 g/mol.

TPCK is an irreversible inhibitor of serine proteases, which are enzymes that cut other proteins at specific amino acid sequences. TPCK works by reacting with the active site of these enzymes and forming a covalent bond, thereby blocking their activity. It has been used in research to study the role of serine proteases in various biological processes, including inflammation, blood coagulation, and cancer.

It is important to note that TPCK is highly toxic and should be handled with appropriate safety precautions, including the use of personal protective equipment (PPE) such as gloves and lab coats, and proper disposal in accordance with local regulations.

Acetoacetates are compounds that are produced in the liver as a part of fatty acid metabolism, specifically during the breakdown of fatty acids for energy. Acetoacetates are formed from the condensation of two acetyl-CoA molecules and are intermediate products in the synthesis of ketone bodies, which can be used as an alternative energy source by tissues such as the brain during periods of low carbohydrate availability or intense exercise.

In clinical settings, high levels of acetoacetates in the blood may indicate a condition called diabetic ketoacidosis (DKA), which is a complication of diabetes mellitus characterized by high levels of ketone bodies in the blood due to insulin deficiency or resistance. DKA can lead to serious complications such as cerebral edema, cardiac arrhythmias, and even death if left untreated.

3-Hydroxybutyric acid, also known as β-hydroxybutyric acid, is a type of ketone body that is produced in the liver during the metabolism of fatty acids. It is a colorless, slightly water-soluble compound with a bitter taste and an unpleasant odor.

In the body, 3-hydroxybutyric acid is produced when there is not enough glucose available to meet the body's energy needs, such as during fasting, starvation, or prolonged intense exercise. It can also be produced in large amounts in people with uncontrolled diabetes, particularly during a condition called diabetic ketoacidosis.

3-Hydroxybutyric acid is an important source of energy for the brain and other organs during periods of low glucose availability. However, high levels of 3-hydroxybutyric acid in the blood can lead to a condition called ketosis, which can cause symptoms such as nausea, vomiting, abdominal pain, and confusion. If left untreated, ketosis can progress to diabetic ketoacidosis, a potentially life-threatening complication of diabetes.

Hydroxybutyrates are compounds that contain a hydroxyl group (-OH) and a butyric acid group. More specifically, in the context of clinical medicine and biochemistry, β-hydroxybutyrate (BHB) is often referred to as a "ketone body."

Ketone bodies are produced by the liver during periods of low carbohydrate availability, such as during fasting, starvation, or a high-fat, low-carbohydrate diet. BHB is one of three major ketone bodies, along with acetoacetate and acetone. These molecules serve as alternative energy sources for the brain and other tissues when glucose levels are low.

In some pathological states, such as diabetic ketoacidosis, the body produces excessive amounts of ketone bodies, leading to a life-threatening metabolic acidosis. Elevated levels of BHB can also be found in other conditions like alcoholism, severe illnesses, and high-fat diets.

It is important to note that while BHB is a hydroxybutyrate, not all hydroxybutyrates are ketone bodies. The term "hydroxybutyrates" can refer to any compound containing both a hydroxyl group (-OH) and a butyric acid group.

Amino acid chloromethyl ketones (AACMKs) are a class of chemical compounds that are widely used in research and industry. They are derivatives of amino acids, which are the building blocks of proteins, with a chloromethyl ketone group (-CO-CH2Cl) attached to the side chain of the amino acid.

In the context of medical research, AACMKs are often used as irreversible inhibitors of enzymes, particularly those that contain active site serine or cysteine residues. The chloromethyl ketone group reacts with these residues to form a covalent bond, which permanently inactivates the enzyme. This makes AACMKs useful tools for studying the mechanisms of enzymes and for developing drugs that target specific enzymes.

However, it is important to note that AACMKs can also be highly reactive and toxic, and they must be handled with care in the laboratory. They have been shown to inhibit a wide range of enzymes, including some that are essential for normal cellular function, and prolonged exposure can lead to cell damage or death. Therefore, their use is typically restricted to controlled experimental settings.

Ketosis is a metabolic state characterized by an elevated level of ketone bodies in the blood or tissues. Ketone bodies are alternative energy sources that are produced when the body breaks down fat for fuel, particularly when glucose levels are low or when carbohydrate intake is restricted. This condition often occurs during fasting, starvation, or high-fat, low-carbohydrate diets like the ketogenic diet. In a clinical setting, ketosis may be associated with diabetes management and monitoring. However, it's important to note that extreme or uncontrolled ketosis can lead to a dangerous condition called diabetic ketoacidosis (DKA), which requires immediate medical attention.

Coenzyme A-transferases are a group of enzymes that catalyze the transfer of Coenzyme A (CoA) from one molecule to another. CoA is a coenzyme that plays a crucial role in various metabolic processes, including the oxidation of carbohydrates, fatty acids, and amino acids.

Coenzyme A-transferases can be further classified into several subfamilies based on their specific functions and the types of molecules they act upon. For example, some CoA-transferases transfer CoA to acyl groups, forming acyl-CoAs, which are important intermediates in fatty acid metabolism. Other CoA-transferases transfer CoA to pyruvate, forming pyruvate dehydrogenase complexes that play a key role in glucose metabolism.

These enzymes are essential for maintaining the proper functioning of various metabolic pathways and are involved in a wide range of physiological processes, including energy production, lipid synthesis, and detoxification. Defects in CoA-transferases can lead to several metabolic disorders, such as fatty acid oxidation disorders and pyruvate dehydrogenase deficiency.

Stereoisomerism is a type of isomerism (structural arrangement of atoms) in which molecules have the same molecular formula and sequence of bonded atoms, but differ in the three-dimensional orientation of their atoms in space. This occurs when the molecule contains asymmetric carbon atoms or other rigid structures that prevent free rotation, leading to distinct spatial arrangements of groups of atoms around a central point. Stereoisomers can have different chemical and physical properties, such as optical activity, boiling points, and reactivities, due to differences in their shape and the way they interact with other molecules.

There are two main types of stereoisomerism: enantiomers (mirror-image isomers) and diastereomers (non-mirror-image isomers). Enantiomers are pairs of stereoisomers that are mirror images of each other, but cannot be superimposed on one another. Diastereomers, on the other hand, are non-mirror-image stereoisomers that have different physical and chemical properties.

Stereoisomerism is an important concept in chemistry and biology, as it can affect the biological activity of molecules, such as drugs and natural products. For example, some enantiomers of a drug may be active, while others are inactive or even toxic. Therefore, understanding stereoisomerism is crucial for designing and synthesizing effective and safe drugs.

A ketogenic diet is a type of diet that is characterized by a significant reduction in carbohydrate intake and an increase in fat intake, with the goal of inducing a metabolic state called ketosis. In ketosis, the body shifts from using glucose (carbohydrates) as its primary source of energy to using ketones, which are produced by the liver from fatty acids.

The typical ketogenic diet consists of a daily intake of less than 50 grams of carbohydrates, with protein intake moderated and fat intake increased to make up the majority of calories. This can result in a rapid decrease in blood sugar and insulin levels, which can have various health benefits for some individuals, such as weight loss, improved blood sugar control, and reduced risk factors for heart disease.

However, it is important to note that a ketogenic diet may not be suitable for everyone, particularly those with certain medical conditions or who are taking certain medications. It is always recommended to consult with a healthcare provider before starting any new diet plan.

In chemistry, an alcohol is a broad term that refers to any organic compound characterized by the presence of a hydroxyl (-OH) functional group attached to a carbon atom. This means that alcohols are essentially hydrocarbons with a hydroxyl group. The simplest alcohol is methanol (CH3OH), and ethanol (C2H5OH), also known as ethyl alcohol, is the type of alcohol found in alcoholic beverages.

In the context of medical definitions, alcohol primarily refers to ethanol, which has significant effects on the human body when consumed. Ethanol can act as a central nervous system depressant, leading to various physiological and psychological changes depending on the dose and frequency of consumption. Excessive or prolonged use of ethanol can result in various health issues, including addiction, liver disease, neurological damage, and increased risk of injuries due to impaired judgment and motor skills.

It is important to note that there are other types of alcohols (e.g., methanol, isopropyl alcohol) with different chemical structures and properties, but they are not typically consumed by humans and can be toxic or even lethal in high concentrations.

Acetone is a colorless, volatile, and flammable liquid organic compound with the chemical formula (CH3)2CO. It is the simplest and smallest ketone, and its molecules consist of a carbonyl group linked to two methyl groups. Acetone occurs naturally in the human body and is produced as a byproduct of normal metabolic processes, particularly during fat burning.

In clinical settings, acetone can be measured in breath or blood to assess metabolic status, such as in cases of diabetic ketoacidosis, where an excess production of acetone and other ketones occurs due to insulin deficiency and high levels of fatty acid breakdown. High concentrations of acetone can lead to a sweet, fruity odor on the breath, often described as "fruity acetone" or "acetone breath."

Aldehydes are a class of organic compounds characterized by the presence of a functional group consisting of a carbon atom bonded to a hydrogen atom and a double bonded oxygen atom, also known as a formyl or aldehyde group. The general chemical structure of an aldehyde is R-CHO, where R represents a hydrocarbon chain.

Aldehydes are important in biochemistry and medicine as they are involved in various metabolic processes and are found in many biological molecules. For example, glucose is converted to pyruvate through a series of reactions that involve aldehyde intermediates. Additionally, some aldehydes have been identified as toxicants or environmental pollutants, such as formaldehyde, which is a known carcinogen and respiratory irritant.

Formaldehyde is also commonly used in medical and laboratory settings for its disinfectant properties and as a fixative for tissue samples. However, exposure to high levels of formaldehyde can be harmful to human health, causing symptoms such as coughing, wheezing, and irritation of the eyes, nose, and throat. Therefore, appropriate safety measures must be taken when handling aldehydes in medical and laboratory settings.

Molecular structure, in the context of biochemistry and molecular biology, refers to the arrangement and organization of atoms and chemical bonds within a molecule. It describes the three-dimensional layout of the constituent elements, including their spatial relationships, bond lengths, and angles. Understanding molecular structure is crucial for elucidating the functions and reactivities of biological macromolecules such as proteins, nucleic acids, lipids, and carbohydrates. Various experimental techniques, like X-ray crystallography, nuclear magnetic resonance (NMR) spectroscopy, and cryo-electron microscopy (cryo-EM), are employed to determine molecular structures at atomic resolution, providing valuable insights into their biological roles and potential therapeutic targets.

Succinic semialdehyde dehydrogenase, also known as hydroxybutyrate dehydrogenase (EC, is an enzyme involved in the metabolism of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). This enzyme catalyzes the oxidation of succinic semialdehyde to succinate, which is a key step in the GABA degradation pathway.

Deficiency in this enzyme can lead to an accumulation of succinic semialdehyde and its downstream metabolite, gamma-hydroxybutyric acid (GHB), resulting in neurological symptoms such as developmental delay, hypotonia, seizures, and movement disorders. GHB is a naturally occurring neurotransmitter and also a recreational drug known as "Grievous Bodily Harm" or "Liquid Ecstasy."

The gene that encodes for succinic semialdehyde dehydrogenase is located on chromosome 6 (6p22.3) and has been identified as ALDH5A1. Mutations in this gene can lead to succinic semialdehyde dehydrogenase deficiency, which is an autosomal recessive disorder.

I'm sorry for any confusion, but "Pentanones" is not a recognized medical term. It is a chemical term that refers to a class of compounds known as ketones, where the parent compound contains five carbon atoms and a ketone functional group. Ketones are organic compounds containing a carbonyl group (a functional group consisting of a carbon atom double-bonded to an oxygen atom: C=O) with the carbon atom also being bonded to two other carbon atoms.

Cyclization is a chemical process that involves forming a cyclic structure or ring-shaped molecule from a linear or open-chain compound. In the context of medicinal chemistry and drug design, cyclization reactions are often used to synthesize complex molecules, including drugs, by creating rings or fused ring systems within the molecule's structure.

Cyclization can occur through various mechanisms, such as intramolecular nucleophilic substitution, electrophilic addition, or radical reactions. The resulting cyclized compounds may exhibit different chemical and biological properties compared to their linear precursors, making them valuable targets for drug discovery and development.

In some cases, the cyclization process can lead to the formation of stereocenters within the molecule, which can impact its three-dimensional shape and how it interacts with biological targets. Therefore, controlling the stereochemistry during cyclization reactions is crucial in medicinal chemistry to optimize the desired biological activity.

Overall, cyclization plays a significant role in the design and synthesis of many pharmaceutical compounds, enabling the creation of complex structures that can interact specifically with biological targets for therapeutic purposes.

Catalysis is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst, which remains unchanged at the end of the reaction. A catalyst lowers the activation energy required for the reaction to occur, thereby allowing the reaction to proceed more quickly and efficiently. This can be particularly important in biological systems, where enzymes act as catalysts to speed up metabolic reactions that are essential for life.

Diabetic ketoacidosis (DKA) is a serious metabolic complication characterized by the triad of hyperglycemia, metabolic acidosis, and increased ketone bodies. It primarily occurs in individuals with diabetes mellitus type 1, but it can also be seen in some people with diabetes mellitus type 2, particularly during severe illness or surgery.

The condition arises when there is a significant lack of insulin in the body, which impairs the ability of cells to take up glucose for energy production. As a result, the body starts breaking down fatty acids to produce energy, leading to an increase in ketone bodies (acetoacetate, beta-hydroxybutyrate, and acetone) in the bloodstream. This process is called ketosis.

In DKA, the excessive production of ketone bodies results in metabolic acidosis, which is characterized by a lower than normal pH level in the blood (< 7.35) and an elevated serum bicarbonate level (< 18 mEq/L). The hyperglycemia in DKA is due to both increased glucose production and decreased glucose utilization by cells, which can lead to severe dehydration and electrolyte imbalances.

Symptoms of diabetic ketoacidosis include excessive thirst, frequent urination, nausea, vomiting, abdominal pain, fatigue, fruity breath odor, and altered mental status. If left untreated, DKA can progress to coma and even lead to death. Treatment typically involves administering insulin, fluid replacement, and electrolyte management in a hospital setting.

Alkenes are unsaturated hydrocarbons that contain at least one carbon-carbon double bond in their molecular structure. The general chemical formula for alkenes is CnH2n, where n represents the number of carbon atoms in the molecule.

The double bond in alkenes can undergo various reactions, such as addition reactions, where different types of molecules can add across the double bond to form new compounds. The relative position of the double bond in the carbon chain and the presence of substituents on the carbon atoms can affect the physical and chemical properties of alkenes.

Alkenes are important industrial chemicals and are used as starting materials for the synthesis of a wide range of products, including plastics, resins, fibers, and other chemicals. They are also found in nature, occurring in some plants and animals, and can be produced by certain types of bacteria through fermentation processes.

Mannich bases are not a medical term, but rather a term used in chemistry to describe a class of compounds. They are named after the German chemist Carl Mannich who first described their synthesis in 1912.

A Mannich base is a compound that contains a carbon atom with three different substituents, including a nitrogen atom from an amine group and two organic groups. It is formed by reacting a ketone or aldehyde with a primary or secondary amine and a formaldehyde or other aldehyde.

Mannich bases have been used in the synthesis of various pharmaceuticals, agrochemicals, and dyes. They are also found in some natural products, such as certain alkaloids. While not directly related to medical definitions, understanding the chemistry of Mannich bases can be important for understanding the structure and function of certain drugs and chemical compounds used in medicine.

Alkadienes are organic compounds that contain two carbon-carbon double bonds in their molecular structure. The term "alka" refers to the presence of hydrocarbons, while "diene" indicates the presence of two double bonds. These compounds can be classified as either conjugated or non-conjugated dienes based on the arrangement of the double bonds.

Conjugated dienes have their double bonds adjacent to each other, separated by a single bond, while non-conjugated dienes have at least one methylene group (-CH2-) separating the double bonds. The presence and positioning of these double bonds can significantly affect the chemical and physical properties of alkadienes, including their reactivity, stability, and spectral characteristics.

Alkadienes are important intermediates in various chemical reactions and have applications in the production of polymers, pharmaceuticals, and other industrial products. However, they can also be produced naturally by some plants and microorganisms as part of their metabolic processes.

Starvation is a severe form of malnutrition, characterized by insufficient intake of calories and nutrients to meet the body's energy requirements. This leads to a catabolic state where the body begins to break down its own tissues for energy, resulting in significant weight loss, muscle wasting, and weakness. Prolonged starvation can also lead to serious medical complications such as organ failure, electrolyte imbalances, and even death. It is typically caused by a lack of access to food due to poverty, famine, or other social or economic factors, but can also be a result of severe eating disorders such as anorexia nervosa.

"Propanols" is a general term that refers to a class of alcohols containing a propanol group, which is a functional group made up of a carbon atom bonded to three hydrogen atoms and a hydroxyl group (-OH). There are two primary structures for propanols: 1-propanol (n-propyl alcohol) and 2-propanol (isopropyl alcohol), which differ in the arrangement of their carbon chain.

1-Propanol, also known as n-propyl alcohol, has a linear structure with the hydroxyl group attached to one end of the carbon chain: CH3CH2CH2OH. It is a colorless liquid that is used as a solvent and in the production of other chemicals.

2-Propanol, also known as isopropyl alcohol or isopropanol, has a branched structure with the hydroxyl group attached to a branch on the second carbon atom: (CH3)2CHOH. It is a colorless, flammable liquid that is widely used as a solvent and disinfectant.

Both 1-propanol and 2-propanol have applications in various industries, including pharmaceuticals, cosmetics, and cleaning products. However, they should be handled with care due to their flammability and potential health hazards, such as irritation of the eyes, skin, and respiratory tract.

Oxidation-Reduction (redox) reactions are a type of chemical reaction involving a transfer of electrons between two species. The substance that loses electrons in the reaction is oxidized, and the substance that gains electrons is reduced. Oxidation and reduction always occur together in a redox reaction, hence the term "oxidation-reduction."

In biological systems, redox reactions play a crucial role in many cellular processes, including energy production, metabolism, and signaling. The transfer of electrons in these reactions is often facilitated by specialized molecules called electron carriers, such as nicotinamide adenine dinucleotide (NAD+/NADH) and flavin adenine dinucleotide (FAD/FADH2).

The oxidation state of an element in a compound is a measure of the number of electrons that have been gained or lost relative to its neutral state. In redox reactions, the oxidation state of one or more elements changes as they gain or lose electrons. The substance that is oxidized has a higher oxidation state, while the substance that is reduced has a lower oxidation state.

Overall, oxidation-reduction reactions are fundamental to the functioning of living organisms and are involved in many important biological processes.

I'm sorry for the confusion, but "Palladium" is not a medical term. It is a chemical element with symbol Pd and atomic number 46. It is a rare and lustrous silvery-white metal discovered in 1803 by William Hyde Wollaston. It's used in various applications, including jewelry, dental work, electronics, and chemical reactions. If you have any medical terms you would like me to define, please let me know!

Acetyl-CoA C-acetyltransferase (also known as acetoacetyl-CoA thiolase or just thiolase) is an enzyme involved in the metabolism of fatty acids and ketone bodies. Specifically, it catalyzes the reaction that converts two molecules of acetyl-CoA into acetoacetyl-CoA, which is a key step in the breakdown of fatty acids through beta-oxidation.

The enzyme works by bringing together two acetyl-CoA molecules and removing a coenzyme A (CoA) group from one of them, forming a carbon-carbon bond between the two molecules to create acetoacetyl-CoA. This reaction is reversible, meaning that the enzyme can also catalyze the breakdown of acetoacetyl-CoA into two molecules of acetyl-CoA.

There are several different isoforms of Acetyl-CoA C-acetyltransferase found in various tissues throughout the body, with differing roles and regulation. For example, one isoform is highly expressed in the liver and plays a key role in ketone body metabolism, while another isoform is found in mitochondria and is involved in fatty acid synthesis.

Alkynes are a type of hydrocarbons that contain at least one carbon-carbon triple bond in their molecular structure. The general chemical formula for alkynes is CnH2n-2, where n represents the number of carbon atoms in the molecule.

The simplest and shortest alkyne is ethyne, also known as acetylene, which has two carbon atoms and four hydrogen atoms (C2H2). Ethyne is a gas at room temperature and pressure, and it is commonly used as a fuel in welding torches.

Alkynes are unsaturated hydrocarbons, meaning that they have the potential to undergo chemical reactions that add atoms or groups of atoms to the molecule. In particular, alkynes can be converted into alkenes (hydrocarbons with a carbon-carbon double bond) through a process called partial reduction, or they can be fully reduced to alkanes (hydrocarbons with only single bonds between carbon atoms) through a process called complete reduction.

Alkynes are important intermediates in the chemical industry and are used to produce a wide range of products, including plastics, resins, fibers, and pharmaceuticals. They can be synthesized from other hydrocarbons through various chemical reactions, such as dehydrogenation, oxidative coupling, or metathesis.

Esters are organic compounds that are formed by the reaction between an alcohol and a carboxylic acid. They are widely found in nature and are used in various industries, including the production of perfumes, flavors, and pharmaceuticals. In the context of medical definitions, esters may be mentioned in relation to their use as excipients in medications or in discussions of organic chemistry and biochemistry. Esters can also be found in various natural substances such as fats and oils, which are triesters of glycerol and fatty acids.

Hydrogenation, in the context of food science and biochemistry, refers to the process of adding hydrogen atoms to certain unsaturated fats or oils, converting them into saturated fats. This is typically done through a chemical reaction using hydrogen gas in the presence of a catalyst, often a metal such as nickel or palladium.

The process of hydrogenation increases the stability and shelf life of fats and oils, but it can also lead to the formation of trans fats, which have been linked to various health issues, including heart disease. Therefore, the use of partially hydrogenated oils has been largely phased out in many countries.

In the field of organic chemistry, imines are a class of compounds that contain a functional group with the general structure =CR-NR', where C=R and R' can be either alkyl or aryl groups. Imines are also commonly referred to as Schiff bases. They are formed by the condensation of an aldehyde or ketone with a primary amine, resulting in the loss of a molecule of water.

It is important to note that imines do not have a direct medical application, but they can be used as intermediates in the synthesis of various pharmaceuticals and bioactive compounds. Additionally, some imines have been found to exhibit biological activity, such as antimicrobial or anticancer properties. However, these are areas of ongoing research and development.

Nonesterified fatty acids (NEFA), also known as free fatty acids (FFA), refer to fatty acid molecules that are not bound to glycerol in the form of triglycerides or other esters. In the bloodstream, NEFAs are transported while bound to albumin and can serve as a source of energy for peripheral tissues. Under normal physiological conditions, NEFA levels are tightly regulated by the body; however, elevated NEFA levels have been associated with various metabolic disorders such as insulin resistance, obesity, and type 2 diabetes.

I'm sorry for any confusion, but "Rhodium" is not a medical term. It is a chemical element with the symbol Rh and atomic number 45. It is a rare, silvery-white, hard, corrosion-resistant, and chemically inert transition metal. It is found in small quantities in platinum or nickel ores along with some other rare metals.

It's primarily used in industrial applications, such as being a key component in catalytic converters in automobiles, which helps to reduce harmful emissions. It's also used in jewelry, electronics, and scientific instruments due to its properties of resistance to corrosion and heat.

Echinacea is a type of herb that is native to North America. It is also known as the purple coneflower and is used in herbal medicine for its alleged ability to boost the immune system and help fight off colds and other infections. The active ingredients in echinacea are thought to be compounds called alkylamides, which may have anti-inflammatory and immune-stimulating effects.

There is some evidence to suggest that echinacea may help reduce the duration and severity of colds when taken at the onset of symptoms, but the overall body of research on its effectiveness is mixed. Some studies have found no significant benefit, while others have reported modest reductions in the length and severity of cold symptoms.

Echinacea is generally considered to be safe when used as directed, but it can cause side effects such as stomach upset, headache, and dizziness in some people. It may also interact with certain medications, so it is important to speak with a healthcare provider before taking echinacea if you are taking any prescription drugs or have any underlying health conditions.

Protease inhibitors are a class of antiviral drugs that are used to treat infections caused by retroviruses, such as the human immunodeficiency virus (HIV), which is responsible for causing AIDS. These drugs work by blocking the activity of protease enzymes, which are necessary for the replication and multiplication of the virus within infected cells.

Protease enzymes play a crucial role in the life cycle of retroviruses by cleaving viral polyproteins into functional units that are required for the assembly of new viral particles. By inhibiting the activity of these enzymes, protease inhibitors prevent the virus from replicating and spreading to other cells, thereby slowing down the progression of the infection.

Protease inhibitors are often used in combination with other antiretroviral drugs as part of highly active antiretroviral therapy (HAART) for the treatment of HIV/AIDS. Common examples of protease inhibitors include saquinavir, ritonavir, indinavir, and atazanavir. While these drugs have been successful in improving the outcomes of people living with HIV/AIDS, they can also cause side effects such as nausea, diarrhea, headaches, and lipodystrophy (changes in body fat distribution).

Butylene glycols are a type of organic compounds that belong to the class of diols, which are chemical compounds containing two hydroxyl groups. Specifically, butylene glycols are composed of a four-carbon chain with two hydroxyl groups located on adjacent carbon atoms.

There are two isomeric forms of butylene glycol: 1,2-butanediol and 1,3-butanediol.

* 1,2-Butanediol (also known as 1,2-butylene glycol) has the hydroxyl groups on the first and second carbon atoms of the chain. It is a colorless, viscous liquid that is used as a solvent, humectant, and antifreeze in various industrial and cosmetic applications.
* 1,3-Butanediol (also known as 1,3-butylene glycol) has the hydroxyl groups on the first and third carbon atoms of the chain. It is also a colorless, viscous liquid that is used as a solvent, humectant, and antifreeze in various industrial and cosmetic applications.

Butylene glycols are generally considered to be safe for use in cosmetics and other consumer products, although they may cause skin irritation or allergic reactions in some individuals. They are also used as intermediates in the synthesis of other chemicals, such as polyesters and polyurethanes.

The liver is a large, solid organ located in the upper right portion of the abdomen, beneath the diaphragm and above the stomach. It plays a vital role in several bodily functions, including:

1. Metabolism: The liver helps to metabolize carbohydrates, fats, and proteins from the food we eat into energy and nutrients that our bodies can use.
2. Detoxification: The liver detoxifies harmful substances in the body by breaking them down into less toxic forms or excreting them through bile.
3. Synthesis: The liver synthesizes important proteins, such as albumin and clotting factors, that are necessary for proper bodily function.
4. Storage: The liver stores glucose, vitamins, and minerals that can be released when the body needs them.
5. Bile production: The liver produces bile, a digestive juice that helps to break down fats in the small intestine.
6. Immune function: The liver plays a role in the immune system by filtering out bacteria and other harmful substances from the blood.

Overall, the liver is an essential organ that plays a critical role in maintaining overall health and well-being.
