acetyl-coenzyme a carboxylase α (acc-alpha) is considered as the key regulatory enzyme in fatty acid biosynthesis. acc-alpha gene is located on caprine chromosome 11 and is polymorphic in many goat breeds. in the current study, we aimed to find possible single nucleotide polymorphisms (snps) in the exon 1 region of the acc-alpha gene in iranian mahabadi goat breed. genomic dna was extracted fro...

conclusions the effect of coadministration of nac and coq10 was neither additive nor synergic in protecting against nihl. results the temporary hearing changes that occurred 1-day post exposure were not significantly different in all groups (p > 0.05). the total recovery (between 1 - 21 days after noise exposure) varied by a frequency increase between 1.08 - 19.10 in the noise group compared to...

objective(s) this study aimed to examine whether acetyl-l-carnitine (alc) was able to reduce cardiac arrhythmias and infarct size in the ischemic-reperfused isolated rat heart. materials and methods the isolated hearts were mounted on a langendorff apparatus then perfused by a modified krebs-henseleit solution during 30 min regional ischemia and 120 min reperfusion (control) or by enriched kreb...

gabapentin is an anticonvulsant widely used in the treatment of epilepsy.an accurate and validated spectrophotometric method was developed as an alternative method to determine gabapentin in pharmaceutical products. this is a simple, accurate, precise, selective and visible spectrophotometric method. the method is based on the measurement of drug absorbance as a result of yellow solution format...

The silent information regulator 2 (Sir2) family of NAD-dependent N-acetyl-protein deacetylases participates in the regulation of gene silencing, chromatin structure, and longevity. In the Sir2-catalyzed reaction, the acetyl moiety of N-acetyl-histone is transferred to the ADP-ribose of NAD, yielding O-acetyl-ADP-ribose and nicotinamide. We hypothesized that, if O-acetyl-ADP-ribose were an impo...

This study investigated the gastroprotective effect of Lcarnitine against indomethacin-induced gastric ulcer in rats and the possible mechanisms underlying this effect. Two sets of experiments were performed. In the first set male albino rats (170-210 g) were randomly allocated into a normal control group, ulcer control group (received a single dose of indomethacin 30 mg/kg po) and three ulcer ...

Acetyl-coenzyme A (acetyl-CoA) is not only an essential intermediate in central carbon metabolism, but also an important precursor metabolite for native or engineered pathways that can produce many products of commercial interest such as pharmaceuticals, chemicals or biofuels. In the yeast Saccharomyces cerevisiae, acetyl-CoA is compartmentalized in the cytosol, mitochondrion, peroxisome and nu...

Acetyl-coenzyme A (acetyl-CoA) formed within the plastid is the precursor for the biosynthesis of fatty acids and, through them, a range of important biomolecules. The source of acetyl-CoA in the plastid is not known, but two enzymes are thought to be involved: acetyl-CoA synthetase and plastidic pyruvate dehydrogenase. To determine the importance of these two enzymes in synthesizing acetyl-CoA...

Transcription of acetyl-CoA carboxylase in avian liver is low during starvation or after consumption of a low-carbohydrate, high-fat diet and high during consumption of a high-carbohydrate, low-fat diet. The role of fatty acids or metabolites derived from fatty acids in the nutritional control of acetyl-CoA carboxylase transcription was investigated by determining the effects of long- and mediu...
