Dietary control of triglyceride and phospholipid synthesis in rat liver slices. (1/1352)

1. The effect of dietary manipulation on the synthesis of triglycerides and phospholipids was investigated by determining the incorporation of labeled long-chain fatty acid or glycerol into these lipids in liver slices derived from normally fed, fasted, and fat-free refed rats. 2. Triglyceride synthesis was affected markedly by the dietary regime of the animal; the lowest rates were measured with fasted rats, and the highest ones with fat-free refed rats. 3. In contrast to triglyceride synthesis, phospholipid synthesis occured at virtually constant rates regardless of the dietary conditions. 4. Addition of large amounts of fatty acid to the incubation mixture resulted in a marked stimulation of triglyceride synthesis, whereas phospholipid synthesis was affected to a much smaller extent. 5. These results indicate that the synthesis of triglycerides and that of phospholipids are controlled independently, and that the availability of fatty acid in the cell contributes to the control of triglyceride synthesis.  (+info)

The synthesis and hydrolysis of long-chain fatty acyl-coenzyme A thioesters by soluble and microsomal fractions from the brain of the developing rat. (2/1352)

1. The specific activities of long-chain fatty acid-CoA ligase (EC6.2.1.3) and of long-chain fatty acyl-CoA hydrolase (EC3.1.2.2) were measured in soluble and microsomal fractions from rat brain. 2. In the presence of either palmitic acid or stearic acid, the specific activity of the ligase increased during development; the specific activity of this enzyme with arachidic acid or behenic acid was considerably lower. 3. The specific activities of palmitoyl-CoA hydrolase and of stearoyl-CoA hydrolase in the microsomal fraction decreased markedly (75%) between 6 and 20 days after birth; by contrast, the corresponding specific activities in the soluble fraction showed no decline. 4. Stearoyl-CoA hydrolase in the microsomal fraction is inhibited (99%) by bovine serum albumin; this is in contrast with the microsomal fatty acid-chain-elongation system, which is stimulated 3.9-fold by albumin. Inhibition of stearoyl-CoA hydrolase does not stimulate stearoyl-CoA chain elongation. Therefore it does not appear likely that the decline in the specific activity of hydrolase during myelogenesis is responsible for the increased rate of fatty acid chain elongation. 5. It is suggested that the decline in specific activity of the microsomal hydrolase and to a lesser extent the increase in the specific activity of the ligase is directly related to the increased demand for long-chain acyl-CoA esters during myelogenesis as substrates in the biosynthesis of myelin lipids.  (+info)

Studies on the influence of fatty acids on pyruvate dehydrogenase interconversion in rat-liver mitochondria. (3/1352)

1. The effect of fatty acids on the interconversion of pyruvate dehydrogenase between its active (nonphosphorylated) and inactive (phosphorylated) forms was measured in rat liver mitochondria respiring in state 3 with pyruvate plus malate and 2-oxoglutarate plus malate and during state 4 to state 3 transition in the presence of different substrates. The content of intramitochondrial adenine nucleotides was determined in the parallel experiments. 2. Decrease of the intramitochondrial ATP/ADP ratio with propionate and its increase with palmitoyl-L-carnitine in state 3 is accompanied by a shift of the steady-state of the pyruvate dehydrogenase system towards the active or the inactive form, respectively. 3. Transition from the high energy state (state4) to the active respiration (state3) in mitochondria oxidizing 2-oxoglutarate or plamitoyl-L-carnitine causes an increase of the amount of the active form of pyruvate dehydrogenase due to the decrease of ATP/ADP ratio in the matrix. 4. No change in ATP/ADP ratio can be observed in the presence of octanoate in mitochondria oxidizing pyruvate or 2-oxoglutarate in state 3 or during state 4 to state 3 transition. Simultanelusly, no significant change in phosphorylation state of pyruvate dehydrogenase occurs and a low amount of the enzyme in the active form is present with octanoate or octanoate plus 2-oxoglutarate. Pyruvate abolishes this effect of octanoate and shifts the steady-state of pyruvate dehydrogenase system towards the active form. 5. These results indicate that fatty acids influence the interconversion of pyruvate dehydrogenase mainly by changing intramitochondrial ATP/ADP ratio. However, the comparison of the steady-state level of the pyruvate dehydrogenase system in the presence of different substrates in various metabolic conditions provides some evidence that accumulation of acetyl-CoA and high level of NADH may promote the phosphorylation of pyruvate dehydrogenase. 6. Pyruvate exerts its protective effect against phosphorylation of pyruvate dehydrogenase in the presence of fatty acids of short, medium or long chain in a manner which depends on its concentration. It is suggested that in isolated mitochondria pyruvate counteracts the effect of acetyl-CoA and NADH on pyruvate dehydrogenase kinase.  (+info)

Histone-hydrocarbon interaction. Partition of histones in aqueous two-phase systems containing poly(ethylene glycol)-bound hydrocarbons. (4/1352)

The hydrophobic properties of histones have been examined with help of the two-phase partition technique using dextran-poly(ethylene glycol)-water systems. We have found that different fatty acid esters of poly(ethylene glycol) interact with total histones in a manner similar to proteins of the type beta-lactoglobulin and serum albumins. Thus the maximum interaction occurs when the fatty acid contains 16-18 carbon atoms. With less than eight carbon atoms in the polymer-bound fatty acid, no histone-hydrocarbon interaction is observed. The interaction of the five individual histone fractions with palmitate depends on the type of salt used and on its concentration. We suggest that the histones can be divided into three groups with decreasing hydrophobic properties: H3, H2a greater than H4, H2b greater than H1.  (+info)

Stereochemistry of the alpha-oxidation of 3-methyl-branched fatty acids in rat liver. (5/1352)

The stereochemistry of the alpha-oxidation of 3-methyl-branched fatty acids was studied in rat liver. R- and S-3-methylhexadecanoic acid were equally well alpha-oxidized in intact hepatocytes and homogenates. Subcellular fractionation studies showed that alpha-oxidation of both isomers is confined to peroxisomes. Dehydrogenation of 2-methylpentadecanal, the end-product of the peroxisomal alpha-oxidation of 3-methylhexadecanoic acid, to 2-methylpentadecanoic acid, followed by derivatization with R-1-phenylethylamine and subsequent separation of the stereoisomers by gas chromatography, revealed that the configuration of the methyl-branch is preserved throughout the whole alpha-oxidation process. Metabolism and formation of the 2-hydroxy-3-methylhexadecanoyl-CoA intermediate were also investigated. Separation of the methyl esters of the four isomers of 2-hydroxy-3-methylhexadecanoic acid was achieved by gas chromatography after derivatization of the hydroxy group with R-2-methoxy-2-trifluoromethylphenylacetic acid chloride and the absolute configuration of the four isomers was determined. Although purified peroxisomes are capable of metabolizing all four isomers of 2-hydroxy-3-methylhexadecanoyl-CoA, they can only form the (2S,3R) and the (2R,3S) isomers. Our experiments exclude the racemization of the 3-methyl branch during the alpha-oxidation process. The configuration of the 3-methyl branch does not influence the rate of alpha-oxidation, but determines the side of the 2-hydroxylation, hence the configuration of the 2-hydroxy-3-methylacyl-CoA intermediates formed during the process.  (+info)

Anandamide activates human platelets through a pathway independent of the arachidonate cascade. (6/1352)

Anandamide (arachidonoylethanolamide, AnNH) is shown to activate human platelets, a process which was not inhibited by acetylsalicylic acid (aspirin). Unlike AnNH, hydroperoxides generated thereof by lipoxygenase activity, and the congener (13-hydroxy)linoleoylethanolamide, were unable to activate platelets, though they counteracted AnNH-mediated stimulation. On the other hand, palmitoylethanolamide neither activated human platelets nor blocked the AnNH effects. AnNH inactivation by human platelets was afforded by a high-affinity transporter, which was activated by nitric oxide-donors up to 225% of the control. The internalized AnNH could thus be hydrolyzed by a fatty acid amide hydrolase (FAAH), characterized here for the first time.  (+info)

Crystal structure of the Mycobacterium tuberculosis enoyl-ACP reductase, InhA, in complex with NAD+ and a C16 fatty acyl substrate. (7/1352)

Enoyl-ACP reductases participate in fatty acid biosynthesis by utilizing NADH to reduce the trans double bond between positions C2 and C3 of a fatty acyl chain linked to the acyl carrier protein. The enoyl-ACP reductase from Mycobacterium tuberculosis, known as InhA, is a member of an unusual FAS-II system that prefers longer chain fatty acyl substrates for the purpose of synthesizing mycolic acids, a major component of mycobacterial cell walls. The crystal structure of InhA in complex with NAD+ and a C16 fatty acyl substrate, trans-2-hexadecenoyl-(N-acetylcysteamine)-thioester, reveals that the substrate binds in a general "U-shaped" conformation, with the trans double bond positioned directly adjacent to the nicotinamide ring of NAD+. The side chain of Tyr158 directly interacts with the thioester carbonyl oxygen of the C16 fatty acyl substrate and therefore could help stabilize the enolate intermediate, proposed to form during substrate catalysis. Hydrophobic residues, primarily from the substrate binding loop (residues 196-219), engulf the fatty acyl chain portion of the substrate. The substrate binding loop of InhA is longer than that of other enoyl-ACP reductases and creates a deeper substrate binding crevice, consistent with the ability of InhA to recognize longer chain fatty acyl substrates.  (+info)

Cysteine 29 is the major palmitoylation site on stomatin. (8/1352)

The 31 kDa membrane protein stomatin was metabolically labeled with tritiated palmitic acid in the human amniotic cell line UAC and immunoprecipitated. We show that the incorporated palmitate is sensitive to hydroxylamine, indicating the binding to cysteine residues. Stomatin contains three cysteines. By expressing a myc-tagged stomatin and substituting the three cysteines by serine, individually or in combination, we demonstrate that Cys-29 is the predominant site of palmitoylation and that Cys-86 accounts for the remaining palmitate labeling. Disruption of Cys-52 alone does not show any detectable reduction of palmitic acid incorporation. Given the organization of stomatin into homo-oligomers, the presence of multiple palmitate chains is likely to increase greatly the affinity of these oligomers for the membrane and perhaps particular lipid domains within it.  (+info)

Our study aimed to examine both the gastrointestinal handling and metabolism of emulsified [1-13C]palmitic acid esterified into a triglyceride in healthy children and patients with cystic fibrosis by measuring excretion of the label in the stool and on the breath as 13CO2. This is the first time that 13C labelled tripalmitin, orally administered as an emulsion, has been used to measure the digestion and absorption of dietary triglycerides in healthy children and patients with cystic fibrosis on habitual pancreatic enzyme replacement treatment by measuring directly the excretion of 13C label in the stool. In healthy children, only a small proportion of the 13C label was excreted in the stool, which is consistent with total stool lipid losses within the normal range of , 5 g/day.1Almost a quarter of the 13C label appeared in stools from patients with cystic fibrosis, with as much as 64% in one child, and there were substantially greater amounts of lipid in the stool when compared with healthy ...

The importance of either carbohydrate or energy restriction in initiating the metabolic response to fasting was studied in five normal volunteers. The subjects participated in two study protocols in a randomized crossover fashion. In one study the subjects fasted for 84 h (control study), and in the other a lipid emulsion was infused daily to meet resting energy requirements during the 84-h oral fast (lipid study). Glycerol and palmitic acid rates of appearance in plasma were determined by infusing [2H5]glycerol and [1-13C]palmitic acid, respectively, after 12 and 84 h of oral fasting. Changes in plasma glucose, free fatty acids, ketone bodies, insulin, and epinephrine concentrations during fasting were the same in both the control and lipid studies. Glycerol and palmitic acid rates of appearance increased by 1.63 +/- 0.42 and 1.41 +/- 0.46 mumol.kg-1.min-1, respectively, during fasting in the control study and by 1.35 +/- 0.41 and 1.43 +/- 0.44 mumol.kg-1.min-1, respectively, in the lipid ...
Palmitoylation of V2R was investigated by immunoprecipitation of receptor proteins expressed transiently in COS.M6 cells and detection of incorporated [3H]palmitic acid. In cells expressing the wild-type glycosylated V2R, [3H]palmitic acid incorporation resulted in the appearance of a broad radioactive band at 45-55 kDa, which is the expected size for the mature receptor form. Deglycosylation with PNGase F produced a sharp band at 40 kDa. As seen in Fig. 2, this band was identical to the band obtained from cells expressing nonglycosylated receptor (17, 18). These results demonstrated that the V2R is palmitoylated and that protein glycosylation was not required to observe palmitoylation.. Analogous to other G protein-coupled receptors, the palmitoylation site was expected to be located 10-12 amino acids downstream of the seventh transmembrane region. Some receptors, such as the α2- and β2-adrenoceptors, contain only one palmitoylated cysteine; others, like rhodopsin and the LH/hCG receptor, ...
To study the mechanism of ether lipid accumulation which is characteristic of many tumors, we have compared the metabolism of lipids in primary rat tracheal epithelial cells and in a cell line derived from a benzo(a)pyrene-induced tumor. Growth of the primary epithelial cells in vitro resulted in the accumulation of alkyldiacylglycerols at levels (10% of total lipid) comparable to those found in the tumor cell line (B2-1). This class of ether lipids could not be detected in normal rat tracheal epithelium in vivo. A double isotope labeling method using [3H]- and [14C]palmitic acid was used to study metabolic stability of lipid classes in the cell cultures. Primary cells and B2-1 cells labeled with palmitic acid showed the greatest loss of label from triacylglycerols and free fatty acids during incubation in unlabeled media. A slight loss of label from the ester linkages of the alkyldiacylglycerols was observed in the primary epithelial cells but not the B2-1 cells. No label was lost from the ...

Palmitic acid (PA) has been for long time negatively depicted for its putative detrimental health effects, shadowing its multiple crucial physiological activities. PA is the most common saturated fatty acid accounting for 20-30% of total fatty acids in the human body and can be provided in the diet or synthesized endogenously via de novo lipogenesis (DNL). PA tissue content seems to be controlled around a well-defined concentration, and changes in its intake do not influence significantly its tissue concentration because the exogenous source is counterbalanced by PA endogenous biosynthesis. Particular physiopathological conditions and nutritional factors may strongly induce DNL, resulting in increased tissue content of PA and disrupted homeostatic control of its tissue concentration. The tight homeostatic control of PA tissue concentration is likely related to its fundamental physiological role to guarantee membrane physical properties but also to consent protein palmitoylation, palmitoylethanolamide
Anyhoo. Half a pound of doner meat down and you are now just ravenous. You fight the hunger off for another 10 minutes, but you know you are on to a looser. You blow another £3.20 on a second portion. Sitting in Mothercares car park, finishing your second kebab, you promise yourself that now you will just drive home and stop eating, and you actually turn on the ignition before the palmitic acid driven hunger breaks your will like a matchstick and you go back for a third portion.

After that its a race within the family to spent the weeks food budget on Friday night doner kebabs.

Exposure of human islets cultivated at 5.5 mmol/l glucose to 0.1, 0.25, and 0.5 mmol/l palmitic acid for 4 days induced a 2.12-, 2.51-, and 3.59-fold increase, respectively, of the number of TUNEL-positive β-cells (Fig. 1). Exposure to 33.3 mmol/l glucose induced a 3.3-fold increase of the number of TUNEL-positive β-cells relative to islets at 5.5 mmol/l glucose (Fig. 1B). Glucose (33.3 mmol/l) together with 0.1-0.5 mmol/l palmitic acid had no additive effect (Fig. 1B). In contrast, the monounsaturated palmitoleic acid (0.5 mmol/l) and oleic acid (0.1-0.5 mmol/l) did not induce β-cell DNA fragmentation (Fig. 1). When added together with the corresponding concentration of palmitic acid, 0.5 mmol/l palmitoleic acid and 0.25-0.5 mmol/l oleic acid reduced the palmitic acid effect on β-cell death (Fig. 1B). Furthermore, 0.5 mmol/l palmitoleic acid and 0.25-0.5 mmol/l oleic acid prevented the β-cells from 33.3 mmol/l glucose-induced apoptosis and limited the apoptotic effect of both, increased ...
The third area of focus relates to chronic pain, a condition that affects 100 million Americans. Recent data indicates that palmitoylethanolamide may have both a solo mechanism of action and a "potentiating" or "synergistic" effect when combined with narcotics and certain other drugs used for the treatment of severe chronic pain. Prismic plans to undertake proof-of-concept clinical studies to demonstrate the "potentiating" effect of our formulation of palmitoylethanolamide when administered concomitantly with drugs such as morphine, oxycodone, hydrocodone, and pregabalin. The studies will assess the effect of concomitant administration of palmitoylethanolamide in terms of "potentiating" (enhancing) the effectiveness of these drugs, allowing for lower doses of the drugs to be used while achieving the desired therapeutic effect. Such results would also be expected to demonstrate a consequent lessening or avoidance of adverse events/side effects and, in the case of opiates/narcotics, potentially, a ...

The main finding of the present study was that myotubes established from type 2 diabetic subjects expressed a primary reduced complete palmitate oxidation with a concomitant increase in the esterification of palmitic acid into phospholipids. Palmitic acid incorporation into DAG and TAG did not differ between the groups, whether under basal conditions or acute insulin stimulation, and TAG content in myotubes established from control and type 2 diabetic subjects did not differ significantly. These results indicate that the reduced lipid oxidation in diabetic muscle observed in vivo may be of genetic origin and that TAG metabolism may not be primarily affected in diabetic muscles under basal physiological conditions.. Previously, it has been described that intracellular TAG is increased (7,9,10) and that oxidation of lipids is reduced in muscle fibers from obese and type 2 diabetic subjects (4,6,27,31); however, the mechanism responsible for these changes has not yet been identified. To gain ...
Final thought: Do we need omega 3 PUFA at anything above the most minimal levels if we are in saturated fat based ketosis? Of course I dont know. But the signal to cope with starvation is palmitic acid (physiological insulin resistance), not DHA. I live in starvation mode, not on a mixed diet with only intermittent access to healthy ruminant fat. I have long wanted to look at the selective release of FFAs from adipocytes in extended starvation. My suspicion is that in the early days after glycogen depletion palmitic acid is preferentially released over other lipids, PUFA are not needed/wanted. By a few weeks all the palmitate is gone and whatever is left then gets released. People like David Blaine suddenly start to feel weak, wobbly and are probably hypoglycaemic once they run out of palmitate and have to release less saturated fats. Two to four weeks if you carry some spare weight. Sauers rats had only ever been fed a low fat omega 6 based diet and had no serious palmitate reserves, PUFA ...

We recently demonstrated that cotyledons of cotton (Gossypium hirsutum L.) seedlings synthesize N-acylphosphatidylethanolamine (NAPE), an unusual acylated derivative of phosphatidylethanolamine (PE), during postgerminative growth (K.D. Chapman and T.S. Moore [1993] Arch Biochem Biophys 301: 21-)33). Here, we report the discovery of an acyltransferase enzyme, fatty acid: diacylphosphatidylethanolamine N-acyltransferase (designated NAPE synthase), that synthesizes NAPE from PE and free fatty acids (FFA) in cottonseed microsomes. [14C]NAPE was synthesized from [14C]palmitic acid and endogenous PE in a time-, pH-, temperature-, and protein concentration-dependent manner. [14C]Palmitic acid was incorporated exclusively into the N-acyl position of NAPE. [14C]palmitoyl coenzyme A (CoA) and [14C]-dipalmitoyl phosphatidylcholine (PC) were poor acyl donors for the synthesis of NAPE (i.e. 200- and 3000-fold lower incorporation efficiency than palmitic acid, respectively). Synthesis of NAPE from ...

Palmitoylethanolamide, a neutraceutical, in nerve compression syndromes: efficacy and safety in sciatic pain and carpal tunnel syndrome Jan M Keppel Hesselink, David J KopskyInstitute for Neuropathic Pain, Bosch en Duin, the Netherlands Abstract: Palmitoylethanolamide (PEA) is an endogenous lipid modulator in animals and humans, and has been evaluated since the 1970s as an anti-inflammatory and analgesic drug in more than 30 clinical trials, in a total of ~6,000 patients. PEA is currently available worldwide as a nutraceutical in different formulations, with and without excipients. Here we describe the results of all clinical trials evaluating PEAâ s efficacy and safety in nerve compression syndromes: sciatic pain and pain due to carpal tunnel syndrome, and review preclinical evidence in nerve impingement models. Both the pharmacological studies as well as the clinical trials supported PEAâ s action as an analgesic compound. In total, eight clinical trials have been published in such entrapment

How much of 16:0 hexadecanoic, palmitic fatty acid is present in Cereals ready-for-eating, KELLOGG, KELLOGGS SMART START Strong Heart Antioxidants Cereal in details, quantity how high or low 16:0 hexadecanoic, palmitic fatty acid nutrient content it has.
Palmitic acid (16:0) is the most common fatty acid (saturated) found in animals, plants and microorganisms. Coenzyme A (CoA) also presents in living organisms, is bound to Palmitic acid for synthesis and oxidates several fatty acids. These 2 elements reacts to form the first metabolite of our pathway 16:CoA, which is generated by the endoplastic reticulum (plastid membrane). AraGEM model is compounded by 1737 metabolites and 1601 reactions. These elements are organized in the stoichiometric matrix S[1737x1601] to use them in the FBA optimization take into account some constraints. Our efforts were aimed at the optimization of Palmitic Acid or Hexadecanoic32 Acid_acc (16:0), which is the precursor of our pathway. 16:0 is located in the cytosol and the reaction takes place using one influx V1 and two effluxes V2, V3. The efflux V2 was incorporated as an exchange reaction in order to generate branch in the original pathway of 16:0 metabolism. As our metabolic pathway is linear starting from 16:0, ...

Palmitoylethanolamide (PEA) is an endogenous fatty acid amide, belonging to the class of nuclear factor agonists. PEA has been demonstrated to bind to a receptor in the cell-nucleus (a nuclear receptor) and exerts a great variety of biological functions related to chronic pain and inflammation. The main target is thought to be the peroxisome proliferator-activated receptor alpha (PPAR-α). PEA also has affinity to cannabinoid-like G-coupled receptors GPR55 and GPR119. PEA cannot strictly be considered a classic endocannabinoid because it lacks affinity for the cannabinoid receptors CB1 and CB2. However, the presence of PEA (and other structurally related N-acylethanolamines) has been known to enhance anandamide activity by an "entourage effect". Several papers have demonstrated that an imbalance of the endocannabinoid system (ECS) and alterations in the levels of PEA occur in acute and chronic inflammation. For instance during β-amyloid-induced neuroinflammation the deregulation of cannabinoid ...
The fat in chocolate comes from cocoa butter and is made up of oleic acid (a heart-healthy monounsaturated fat), stearic and palmitic acids. Stearic and palmitic acids are saturated fats. Saturated fats are linked to increases in LDL cholesterol and the risk of heart disease. Research shows stearic acid appears to have a neutral effect on cholesterol. Although palmitic acid does affect cholesterol levels, it only makes up one-third of the fat calories in chocolate. This does not mean you can eat all the dark chocolate youd like ...
It has been shown previously that commercially available solid phase extraction (SPE) columns release contaminants such as palmitic acid and stearic acid during separation of lipid classes. The presence of contaminating fatty acids in the fatty acid fraction is particularly troublesome. We here confirm that the overwhelming majority of the contaminants originate from the barrels, and have identified two contaminants as palmitic acid and stearic acid or their equivalents. We urge readers to take fatty acid contaminants into careful consideration when planning their experiments, and if necessary use sorbent packed in glass barrels instead of plastic such as polypropylene.
PC(o-18:1(11Z)/16:0) is a phosphatidylcholine (PC or GPCho). It is a glycerophospholipid in which a phosphorylcholine moiety occupies a glycerol substitution site. As is the case with diacylglycerols, glycerophosphocholines can have many different combinations of fatty acids of varying lengths and saturation attached at the C-1 and C-2 positions. Fatty acids containing 16, 18 and 20 carbons are the most common. PC(o-18:1(11Z)/16:0), in particular, consists of one chain of Vaccenyl alcohol at the C-1 position and one chain of palmitic acid at the C-2 position. The Vaccenyl alcohol moiety is derived from beef fat, while the palmitic acid moiety is derived from fish oils, milk fats, vegetable oils and animal fats. Phospholipids, are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and signaling. While most phospholipids have a saturated fatty acid on C-1 and an unsaturated fatty acid on C-2 of the glycerol backbone, the fatty acid ...

Triple negative breast cancer (TNBC) is an aggressive cancer, which is resistant to the majority of available chemotherapies. We have recently identified significant differences in the levels of membrane lipids and fatty acids between two distinct TNCB metabolic subtypes (MST2 and MST3) (Beatty et al., 2014, manuscript submitted). Fatty acid synthesis has recently been discussed as potential pharmaceutical target.. In order to evaluate whether glucose or glutamine is the preferred carbon source for palmitic acid synthesis, TNBC cell lines (BT549 and HCC1806) were fed with fully labelled glucose and fully labelled glutamine ([U-13C6]glucose and [U-13C5]glutamine) in independent experiments. Fully labelled glutamine allows conclusions on total usage of glutamine via the reductive and the oxidative part of the TCA-cycle. In order to assess the contribution of glutamine to palmitic acid synthesis via the reductive pathway we fed the subtypes with single labelled glutamine [5-13C1]glutamine. ...

Exocytosis, the fusion of a vesicle to a cellular membrane, involves a protein named SNAP-25. This protein, containing two alpha helices connected with a linker region, is localized to the cell membrane via palmitic acids attached to the cysteine residues of its linker region in a process called palmitoylation. Are cysteine residues of the SNAP-25 linker region palmitoylated in an ordered manner and to a particular extent? The answer to this question may give insight into the regulated nature of exocytosis. While it is generally accepted that SNAP-25 must be palmitoylated in order to perform its exocytotic functions, the details surrounding this process are still being discovered, defined, and understood. In these studies we replicate the oxidation, reduction, and palmitoylation of SNAP-25 in vitro. Palmitoylating SNAP-25 in vitro, a process which occurs regularly in vivo, allows us to determine the extent of palmitoylation. In vitro palmitoylation of SNAP-25 was studied both with and without a native

Transport in the respiratory chain of electrons from FADH2 and NADH will lead to the synthesis of five high-energy phosphates (Chapter 12) for each of the first seven acetyl-CoA molecules formed by β-oxidation of palmitate (7 × 5 = 35). A total of 8 mol of acetyl-CoA is formed, and each will give rise to 12 mol of ATP on oxidation in the citric acid cycle, making 8 × 12 = 96 mol. Two must be subtracted for the initial activation of the fatty acid, yielding a net gain of 129 mol of ATP per mole of palmitate, or 129 × 51.6* = 6656 kJ. This represents 68% of the free energy of combustion of palmitic acid. ...

Insulin degludec (INN/USAN) is an ultralong-acting basal insulin analogue that was developed by Novo Nordisk under the brand name Tresiba. It is administered via subcutaneous injection once daily to help control the blood sugar level of those with diabetes. It has a duration of action that lasts up to 42 hours (compared to 18 to 26 hours provided by other marketed long-acting insulins such as insulin glargine and insulin detemir), making it a once-daily basal insulin, that is one that provides a base insulin level, as opposed to the fast and short acting bolus insulins. Insulin degludec is a modified insulin that has one single amino acid deleted in comparison to human insulin, and is conjugated to hexadecanedioic acid via gamma-L-glutamyl spacer at the amino acid lysine at position B29. A significant side effect of insulin therapy is hypoglycemia. A meta-analysis of clinical trials published in July 2012 found 39 to 47.9 events of hypoglycemia (defined as blood glucose ...
Title:Biosynthetic Pathways of Bioactive N-Acylethanolamines in Brain. VOLUME: 12 ISSUE: 1. Author(s):Kazuhito Tsuboi, Natsuki Ikematsu, Toru Uyama, Dale G. Deutsch, Akira Tokumura and Natsuo Ueda. Affiliation:Department of Biochemistry, Kagawa University School of Medicine, 1750-1 Ikenobe, Miki, Kagawa 761-0793, Japan.. Keywords:N-Acylethanolamine, anandamide, biosynthesis, NAPE-PLD, oleoylethanolamide, palmitoylethanolamide, phospholipid, plasmalogen. Abstract:Ethanolamides of long-chain fatty acids are a class of endogenous lipid mediators generally referred to as Nacylethanolamines (NAEs). NAEs include anti-inflammatory and analgesic palmitoylethanolamide, anorexic oleoylethanolamide, and the endocannabinoid anandamide. Since the endogenous levels of NAEs are principally regulated by enzymes responsible for their biosynthesis and degradation, these enzymes are expected as targets for the development of therapeutic agents. Thus, a better understanding of these enzymes is indispensable. The ...
Two meta-analysis have examined the effect of palmitic acid on serum cholesterol. In a 1997 study based on 134 clinical studies, British researchers concluded that, compared to carbohydrates, palmitic acid raises blood cholesterol levels (Clarke et al. 1997). In 2003, Dutch scientists conducted a meta-analysis of 35 clinical studies (Mensink et l. 2003) and examined what many experts consider the best indicator of heart-disease risk: the ratio of total cholesterol to HDL cholesterol Institute of Medicine, National Academies 2002). Palmitic acid increased the total: HDL cholesterol ratio more than other saturated fatty acids, including lauric acid and myristic acid, which are abundant in palm kernel oil. Palm oil increases the total: HDL cholesterol ratio more than the average U.S. or British dietary fat (Jensen et al. 1999; Keys et al. 1957). That finding indicates that, in terms of blood cholesterol, palm oil is somewhat more harmful than the average U.S. dietary fat and much more harmful than ...
The oil contents of hazelnut samples were found low at the first harvest periods. The oil contents of the first harvest period ranged from 12.3% to 6.51%. The moisture contents of nuts were found low in the same period. The oil contents of hazelnuts harvested at the last harvest period were ranged between 53.40% (sharp) to 66.11 (black). In general, palmitic, stearic, oleic, linoleic acid were identified as dominant fatty acids. Depending on the cultivar and harvest, the oleic acid have been identified at the highest rate and have been partial differences among the varieties. The oleic acid contents of varieties were determined between 74.79% to 85.58% depending on harvest period. Linoleic acid content was ranged from 5.70 to 15.64 %, palmitic acid content ranged from 4.92% to 7.31%. As other fatty acids was found at the minor level. The highest palmitic, oleic and linoleic acid contents have been identified respectively in Tombul (II.harvest), Black (II.harvest) and Tombul (I.harvest) ...
