Effects of glucagon and insulin on lipolysis and ketogenesis in sheep. (1/381)

The hepatic and portal productions of acetoacetate and beta-hydroxybutyrate and lipolysis were studied in normal and insulin-controlled alloxan-diabetic sheep. Since hyperinsulinemia is associated with glucagon administration, the latter group of sheep were used to maintain constant plasma insulin levels. After control values were obtained glucagon was infused intraportally at 90 mug/hr for two hours. The ketone body production by portal drained viscera was not significantly affected by glucagon. In alloxanized sheep, glucagon significantly (P less than 0.01) increased net hepatic production of acetoacetate (from -0.54 +/- 0.08 to 0.46 +/- 0.07 g/hr). Lipolysis also increased. However, in the normal sheep, hyperinsulinemia prevented any stimulatory effect of glucagon on hepatic ketogenesis and lipolysis. Therefore, while glucagon appears capable of stimulating ketogenesis andlipolysis, these effects are readily suppressed by insulin.  (+info)

Evidence for an inducible nucleotide-dependent acetone carboxylase in Rhodococcus rhodochrous B276. (2/381)

The metabolism of acetone was investigated in the actinomycete Rhodococcus rhodochrous (formerly Nocardia corallina) B276. Suspensions of acetone- and isopropanol-grown R. rhodochrous readily metabolized acetone. In contrast, R. rhodochrous cells cultured with glucose as the carbon source lacked the ability to metabolize acetone at the onset of the assay but gained the ability to do so in a time-dependent fashion. Chloramphenicol and rifampin prevented the time-dependent increase in this activity. Acetone metabolism by R. rhodochrous was CO2 dependent, and 14CO2 fixation occurred concomitant with this process. A nucleotide-dependent acetone carboxylase was partially purified from cell extracts of acetone-grown R. rhodochrous by DEAE-Sepharose chromatography. Analysis by sodium dodecyl sulfate-polyacrylamide gel electrophoresis suggested that the acetone carboxylase was composed of three subunits with apparent molecular masses of 85, 74, and 16 kDa. Acetone metabolism by the partially purified enzyme was dependent on the presence of a divalent metal and a nucleoside triphosphate. GTP and ITP supported the highest rates of acetone carboxylation, while CTP, UTP, and XTP supported carboxylation at 10 to 50% of these rates. ATP did not support acetone carboxylation. Acetoacetate was determined to be the stoichiometric product of acetone carboxylation. The longer-chain ketones butanone, 2-pentanone, 3-pentanone, and 2-hexanone were substrates. This work has identified an acetone carboxylase with a novel nucleotide usage and broader substrate specificity compared to other such enzymes studied to date. These results strengthen the proposal that carboxylation is a common strategy used for acetone catabolism in aerobic acetone-oxidizing bacteria.  (+info)

Comparison of metabolism of free fatty acid by isolated perfused livers from male and female rats. (3/381)

Livers from normal, fed male and female rats were perfused with different amounts of [1-14C]oleate under steady state conditions, and the rates of uptake and utilization of free fatty acid (FFA) were measured. The uptake of FFA by livers from either male or female rats was proportional to the concentration of FFA in the medium. The rate of uptake of FFA, per g of liver, by livers from female rats exceeded that of the males for the same amount of FFA infused. The incorporation by the liver of exogenous oleic acid into triglyceride, phospholipid, and oxidation products was proportional to the uptake of FFA. Livers from female rats incorporated more oleate into triglyceride (TG) and less into phospholipid (PL) and oxidation products than did livers from male animals. Livers from female rats secreted more TG than did livers from male animals when infused with equal quantities of oleate. The incorporation of endogenous fatty acid into TG of the perfusate was inhibite) by exogenous oleate. At low concentrations of perfusate FFA, however, endogenous fatty acids contributed substantially to the increased output of TG by livers from female animals. Production of 14CO2 and radioactive ketone bodies increased with increasing uptake of FFA. The partition of oleate between oxidative pathways (CO2 production and ketogenesis) was modified by the availability of the fatty acid substrate with livers from either sex. The percent incorporation of radioactivity into CO2 reached a maximum, whereas incorporation into ketone bodies continued to increase. The output of ketone bodies was dependent on the uptake of FFA, and output by livers from female animals was less than by livers from male rats. The increase in rate of ketogenesis was dependent on the influx of exogenous FFA, while ketogenesis from endogenous sources remained relatively stable. The output of glucose by the liver increased with the uptake of FFA, but no difference due to sex was observed. The output of urea by livers from male rats was unaffected by oleate, while the output of urea by livers from females decreased as the uptake of FFA increased. A major conclusion to be derived from this work is that oleate is not metabolized identically by livers from the two sexes, but rather, per gram of liver, livers from female rats take up and esterify more fatty acid to TG and oxidize less than do livers from male animals; livers from female animals synthesize and secrete more triglyceride than do livers from male animals when provided with equal quantities of free fatty acid.  (+info)

Metabolic effect of alpha-and the beta-adrenergic stimulation of rat submaxillary gland in vitro. (4/381)

1. Incubation of submaxillary-gland slices with isoproterenol, a beta-adrenergic agonist, stimulated glucose removal by 41% and decreased tissue [glucose 6-phosphate] by 50%. Propranolol blocked these effects of isoproterenol. 2. Phenylephrine, an alpha-adrenergic agonist, stimulated glucose removal by 35% and decreased tissue [glucose 6-phosphate] by 75%. In addition, phenylephrine also completely overcame the inhibition of pyruvate removal caused by acetoacetate metabolism and decreased tissue [atp] by 45%. Phentolamine blocked the effects of phenylephrine. 3. In contrast with beta-adrenergic stimulation, alpha-adrenergic stimulation required exogenous Ca2+. 4. These results explain the different metabolic responses of the submaxillary gland to adrenaline in the presence and absence of exogenous Ca2+.  (+info)

Effect of hyperketonemia on plasma lipid peroxidation levels in diabetic patients. (5/381)

OBJECTIVE: This study was undertaken to examine the effect of ketosis on plasma lipid peroxidation levels in diabetic patients. RESEARCH DESIGN AND METHODS: Plasma levels of lipid peroxidation products (malondialdehyde) and ketone bodies (acetoacetate and beta-hydroxybutyrate) were determined in diabetic patients (n = 70) and age-matched normal volunteers (n = 25). Diabetic patients with total ketone body levels > 1.0 mmol/l were considered hyperketonemic, and those with levels < or = 1.0 mmol/l were considered normoketonemic. RESULTS: After normalization versus total lipids, levels of lipid peroxidation were significantly higher in the plasma of hyperketonemic diabetic patients (P < 0.05), but not in normoketonemic diabetic patients, compared with age-matched normal volunteers. In addition, low ketonemia was associated with lower lipid peroxidation levels when lipid peroxidation and ketonemia were determined in the same patient (n = 7) at two different clinic visits. CONCLUSIONS: This study demonstrated an association between hyperketonemia and increased lipid peroxidation levels in diabetic patients, which suggests that ketosis is a risk factor in the elevated lipid peroxidation levels associated with diabetes. Further investigation is needed to determine whether antioxidant supplementation can be particularly beneficial in reducing lipid peroxidation and complications in type 1 diabetic patients who frequently encounter ketosis.  (+info)

The metabolic effects of estriol in female rat liver. (6/381)

The effects of estriol on oxygen uptake, glucose release, lactate and pyruvate production, beta-hydroxybutyrate and acetoacetate production in perfused rat liver as well as, carbon uptake in rat liver and intracellular calcium in isolated Kupffer cells were investigated. Basal oxygen consumption of perfused liver increased significantly in estriol or ethanol-treated rats. But these increased effects were blocked by gadolinium chloride pretreatment. In a metabolic study, pretreatment with estriol resulted in a decrease in glucose production and in glycolysis while an increase in ketogenesis. A more oxidized redox state of the mitochondria was indicated by increased ratios of perfusate [lactate]/[pyruvate] and decreased ratios of perfusate [beta-hydroxybutyrate]/[acetoacetate]. Carbon uptake of Kupffer-cell increased significantly in estriol-treated rats. But these increased uptake were not shown in rats pre-treated by gadolinium chloride blocking phagocytosis. In isolated Kupffer cells from estriol-treated rats, intracellular calcium was more significantly increased after addition of lipopolysaccharide (LPS) than in controls. These findings suggest that the metabolic effects of estriol (two mg per 100 mg body wt) can be summarized to be highly toxic in rat liver, and these findings suggest that oral administration of estrogens may induce hepatic dysfunctions and play a role in the development of liver disease.  (+info)

Hyperketonemia can increase lipid peroxidation and lower glutathione levels in human erythrocytes in vitro and in type 1 diabetic patients. (7/381)

Recent studies have suggested that elevated cellular lipid peroxidation may play a role in the development of cellular dysfunction and other complications of diabetes. People with type 1 diabetes frequently encounter elevated levels of the ketone bodies acetoacetate (AA), beta-hydroxybutyrate (BHB), and acetone (ACE). This study was undertaken to test the hypothesis that ketosis might increase lipid peroxidation and lower glutathione (GSH) levels of red blood cells (RBCs) in diabetic patients. This study demonstrates that incubation of AA with normal RBCs in phosphate-buffered saline (37 degrees C for 24 h) resulted in marked GSH depletion, oxidized glutathione accumulation, hydroxyl radical generation, and increased membrane lipid peroxidation. Increases in oxygen radicals and lipid peroxidation and depletion of GSH in RBCs were not observed with BHB or ACE treatments. Similarly, there was a significant generation of superoxide ion radicals even in a cell-free buffer solution of AA, but not in that of BHB. The presence of BHB together with AA did not influence the capacity of AA to generate oxygen radicals in a cell-free solution or the increase in lipid peroxidation of RBCs incubated with AA. The antioxidants vitamin E and N-acetylcysteine (NAC) blocked increase in lipid peroxidation in AA-treated RBCs. To examine the effects of ketone bodies in vivo, studies were performed that showed a significant decrease in GSH and an increase in lipid peroxidation levels in RBCs of hyperketonemic diabetic patients, but not in normoketonemic type 1 diabetic patients, when compared with age-matched normal subjects. This study demonstrates that elevated levels of the ketone body AA can increase lipid peroxidation and lower GSH levels of RBCs in people with type 1 diabetes.  (+info)

In vivo suppressor mutations correct a murine model of hereditary tyrosinemia type I. (8/381)

Hereditary tyrosinemia type I and alkaptonuria are disorders of tyrosine catabolism caused by deficiency of fumarylacetoacetate hydrolase (FAH) and homogentisic acid dioxygenase (HGD), respectively. Tyrosinemia is a severe childhood disease that affects the liver and kidneys, but alkaptonuria is a more benign adult disorder in comparison. Because HGD is upstream of FAH in the tyrosine pathway, mice doubly mutant in both enzymes were found to be protected from the liver and renal damage of tyrosinemia as hypothesized. Mice mutant at the tyrosinemic locus but heterozygous for alkaptonuria spontaneously developed clonal nodules of functionally normal hepatocytes that were able to rescue the livers of some mice with this genotype. This phenotypic rescue was a result of an inactivating mutation of the wild-type homogentisic acid dioxygenase gene, thus presenting an example of an in vivo suppressor mutation in a mammalian model.  (+info)

Hepatic steatosis is often seen in patients with chronic hepatitis C (CH-C). It is still unclear whether these patients have an impaired mitochondrial β-oxidation. In this study we assessed mitochondrial β-oxidation in CH-C patients by investigating ketogenesis during fasting. This study consisted of thirty patients with CH-C. Serum levels of insulin and hepatitis C virus (HCV) core protein were measured by chemiluminescence enzyme immunoassay. The subjects were then fasted, and venous blood samples were drawn 12 h and 15 h after the start of fasting. The levels of blood ketone bodies were measured by an enzymatic cycling method. The rate of change in total ketone body concentration was compared with that in eight healthy volunteers. The rate of change in total ketone body concentration between 12 h and 15 h after the start of fasting was significantly lower in CH-C patients than in healthy volunteers (129.9% (8.5-577.3%) vs. 321.6% (139.6-405.4%); P |0.01).

Absorption Oral absorption The substance is assumed to be hydrolytically unstable and will therefore be subject to rapid hydrolysis in the mammalian gastrointestinal tract. Systemic exposure to the intact substance is therefore unlikely; however systemic exposure to the hydrolysis products may occur. Based on the structure of the molecule, the hydrolysis products are predicted to be acetylacetone, ethyl acetoacetate, 1,3-propanediol and hydrated titanium oxides. Titanium oxides are of very low water solubility and are not absorbed from the gastrointestinal tract (1). The other hydrolysis products (acetylacetone, ethyl acetoacetate, 1,3-propanediol) are low molecular weight and water-soluble, and are therefore likely to be absorbed from the gastrointestinal tract to a significant extent. The OECD 422 screening study reports some findings (reduced weight gain, decreased serum T4 concentration) at the highest dose level of 750 mg/kg bw/d that are consistent with systemic exposure (and therefore ...

BHYD - Clinical: Beta-Hydroxybutyrate, SerumBHYD - Clinical: Beta-Hydroxybutyrate, Serum
BHYD : Beta-hydroxybutyrate (BHB) is 1 of 3 sources of ketone bodies. Its relative proportion in the blood (78%) is greater than the other 2 ketone bodies, acetoacetate (20%) and acetone (2%). During carbohydrate deprivation (starvation, digestive disturbances, frequent vomiting), decreased carbohydrate utilization (diabetes mellitus), glycogen storage diseases, and alkalosis, acetoacetate production increases. The increase may exceed the metabolic capacity of the peripheral tissues. As acetoacetate accumulates in the blood, a small amount is converted to acetone by spontaneous decarboxylation. The remaining and greater portion of acetoacetate is converted to BHB.

The Carb-Sane Asylum: Toxic!The Carb-Sane Asylum: Toxic!
As I stated in my last discussion of ketosis, I think it is telling, and downright intuitive, that if ketosis were some preferred or desired metabolic state, our bodies would not come out of that state so easily. Folks limiting protein intake to force ketosis after their bodies adapt to biologically zero carb diets are forcing their bodies into a state theyd rather not be in. While non-diabetic ketone levels are not toxic (long term effects are unknown, but lets limit it to acute toxicity) in disease where dose makes the poison, they most certainly are. Then lets look at the notion of dietary ketones. We really dont have such a thing, though the LD50 for acetone does appear to be a bit higher than one might expect. Still I wouldnt suggest anyone run out to their local home improvement or beauty supply store to buy the pure stuff and swig it with dinner. I couldnt find anything for beta hydroxybutyrate or acetoacetic acid but thats irrelevant anyway as I know no dietary source of either. ...

United States Patent 3,212,855 DIAGNOSTIC DEVICE Ray Mast, John Rebar, Jr., and Joseph Fraser, Elkhart, Ind., assignors to Miles Laboratories, Inc., Elkhart, Ind., a corporation of Indiana N0 Drawing. Filed Aug. 6, 1962, Ser. No. 214,867 7 Claims. (Cl. 23253) This invention relates to an improved diagnostic composition and to a method for its preparation. In particular, this invention is concerned with a diagnostic test useful in qualitative detection and quantitative determination of ketone bodies in body fluids, especially acetoacetic acid (beta-ketobutyric acid) in urine. More particularly, this invention is concerned with a diagnostic test reagent composition which is incorporated upon a bibulous carrier. The fats utilized by the body normally undergo complete oxidation with formation of carbon dioxide and water. Since the fatty acid molecules have long chains of carbon atoms, it is theorized that a large number of intermediate products are formed during the oxidation and under normal ...

Ketone-body metabolism in tumour-bearing rats | Biochemical JournalKetone-body metabolism in tumour-bearing rats | Biochemical Journal
During starvation for 72 h, tumour-bearing rats showed accelerated ketonaemia and marked ketonuria. Total blood [ketone bodies] were 8.53 mM and 3.34 mM in tumour-bearing and control (non-tumour-bearing) rats respectively (P less than 0.001). The [3-hydroxybutyrate]/[acetoacetate] ratio was 1.3 in the tumour-bearing rats, compared with 3.2 in the controls at 72 h (P less than 0.001). Blood [glucose] and hepatic [glycogen] were lower at the start of starvation in tumour-bearing rats, whereas plasma [non-esterified fatty acids] were not increased above those in the control rats during starvation. After functional hepatectomy, blood [acetoacetate], but not [3-hydroxybutyrate], decreased rapidly in tumour-bearing rats, whereas both ketone bodies decreased, and at a slower rate, in the control rats. Blood [glucose] decreased more rapidly in the hepatectomized control rats. Hepatocytes prepared from 72 h-starved tumour-bearing and control rats showed similar rates of ketogenesis from palmitate, and ...

NAD is used in the conversion of βHB to acetoacetate (AcAc + NADH ⇌ βHB + NAD). Due to the depletion of NAD, βHB is the predominant ketone product formed. Normally, the ratio of acetoacetate to βHB is 1:1; however, in alcoholic ketoacidosis, the ratio can be 1:7 or higher.5 Once the NADH:NAD returns to normal, lactate levels decrease and acetoacetate increases.1 The ratio of βHB to acetoacetate is also much higher in alcoholic ketoacidosis than in diabetic ketoacidosis.1 The high NADH:NAD ratio also results in increased lactate production, so lactate levels are higher than normal in alcoholic ketoacidosis but not as high as in shock or sepsis. Acetoacetate is metabolized to acetone so that acetone and its metabolites are elevated and may cause an osmolal gap. ...

Nobel :: 1964 - Feodor LynenNobel :: 1964 - Feodor Lynen
Feodor Lynen (1911-1979) was awarded half the 1964 Nobel Prize in Physiology and Medicine for his discoveries concerning the mechanism and regulation of cholesterol and fatty acid metabolism.While studying the intermediary metabolism in cells -- in which energy is extracted from cellular nutrients and used to build cellular components -- and the mechanisms of metabolic regulation, he found that acetylation of coenzyme A is the first step in a chain of reactions leading to the formation of cholesterol and fatty acids. Lynen also studied the Pasteur effect (the inhibiting effect of oxygen on yeast fermentation); acetic acid degradation in yeast; the chemical structure of acetic acid in activated isoprene, activated carboxylic acid, and cytohaemin; the degradation of fatty acids and formation of acetoacetic acid; the degradation of tartaric acid; and the biosynthesis of cysteine, terpenes, rubber, and fatty acids ...

JCI - Malonyl-CoA: the regulator of fatty acid synthesis and oxidationJCI - Malonyl-CoA: the regulator of fatty acid synthesis and oxidation
Ketogenesis, the production of acetoacetate and β-hydroxybutyrate from oxidation of long-chain fatty acids, occurs only in the liver. When glucose production is insufficient, the body shifts to a lipid-based economy. However, the brain cannot oxidize fatty acids for energy, so the production of ketones is protective (1, 2). It is quite remarkable how many distinguished scientists began to study ketogenesis decades ago, among them the Nobel laureates Professors H.A. Krebs and Feodor Lynen. Early on, a widespread belief was that a deficiency of oxaloacetate in the tricarboxylic acid cycle shunted acetyl-CoA derived from fatty acid oxidation into acetoacetate, as described in an excellent lecture on this history published by Professor Krebs in 1966 (3). Indeed, acetoacetate is the preferred metabolic substrate in mammalian cells, chosen above glucose, fatty acids, and other substrates (1, 2). However, oxidation of acetoacetate requires the enzyme succinyl-CoA:3-ketoacid-CoA transferase, which is ...

Acetone also arises in small amounts as a biologically inert side product. Ketone body production is regulated primarily by availability of acetyl CoA.

The rate of ketone body production increases in starvation. ...

The role of leucine in ketogenesis in starved rats | Biochemical JournalThe role of leucine in ketogenesis in starved rats | Biochemical Journal
The quantitative significance of the conversion in vivo of L-[U-14C]leucine to ketone bodies was determined in rats starved for 3 or 48 h. In animals starved for 3 h, 4.4% of ketone-body carbon is derived from the metabolism of leucine, and in rats starved for 48 h the corresponding value is 2.3%. This conversion occurs rapidly, and the specific radioactivity of ketone bodies in blood is maximal at 2 min after the intravenous injection of labelled leucine for both periods of starvation. The flux of leucine in the blood is 1.01 and 1.04 mumol/min per 100 g body wt. respectively for animals starved for 3 and 48 h. The specific radioactivity of blood ketone bodies was compared at 2 min after the injection of labelled leucine, lysine and phenylalanine. The specific radioactivity was 4-5 fold higher with leucine than with lysine or phenylalanine. ...
