General description

Acetyl-CoA is an essential cofactor and carrier of acyl groups in enzymatic acetyl transfer reactions. It is formed either by the oxidative decarboxylation of pyruvate in mitochondria, by the oxidation of long-chain fatty acids, or by the oxidative degradation of certain amino acids. Acetyl-CoA is the starting compound for the citric acid cycle (Kreb′s cycle). It is also a key precursor in lipid biosynthesis, and the source of all fatty acid carbons. Acetyl-CoA positively regulates the activity of pyruvate carboxylase. It is a precursor of the neurotransmitter acetylcholine. Histone acetylases (HAT) use Acetyl-CoA as the donor for the acetyl group used in the post-translational acetylation reactions of histone and non-histone proteins.

Acetyl-Coenzyme A acts as an indicator of fat, sugar, and protein levels and shows up on the nutritional status. Thus, starvation greatly reduces the level of acetyl-CoA, which stimulates the process of autophagy. In lowered glucose condition, acetyl-CoA participates in the production of ATP. Increased acetyl-CoA levels are observed in prostate cancer due to elevated fatty acid utilization and thus provides an additional energy source for the tumor cell growth. Nutrition deprivation, changes the levels of certain metabolites, including acetyl-CoA, which stimulates epigenetic modifications that would affect the central nervous system.

Application

Acetyl-Coenzyme A Assay Kit has been used to quantify the level of acetyl-CoA in astrocytes exposed to recombinant HIV protein Tat and Cocaine. It has also been used to study the mitochondrial metabolism by evaluating the levels of acetyl-CoA using hypoxia induced stress in primary human ventricular cardiomyocytes.

Suitability

Suitable for the measurement of Acetyl CoA in a variety of biological samples

Principle

Acetyl-CoA concentration is determined by a coupled enzyme assay, which results in a fluorometric (λex = 535/λem = 587 nm) product, proportional to the Acetyl-CoA present. Typical sensitivities of detection for this kit are 10-1000 pmole of Acetyl CoA. This kit is a highly sensitive assay for determining Acetyl-CoA level in a variety of biological samples.

Glutamine Metabolism is Dysregulated in Many Cancer Cells

Sigma-Aldrich presents an article about how proliferatively active cells require both a source of carbon and of nitrogen for the synthesis of macromolecules. Although a large proportion of tumor cells utilize aerobic glycolysis and shunt metabolites away from mitochondrial oxidative phosphorylation, many tumor cells exhibit increased mitochondrial activity.

Aerobic Glycolysis and the Warburg Effect

We presents an article about the Warburg effect, and how it is the enhanced conversion of glucose to lactate observed in tumor cells, even in the presence of normal levels of oxygen. Otto Heinrich Warburg demonstrated in 1924 that cancer cells show an increased dependence on glycolysis to meet their energy needs, regardless of whether they were well-oxygenated or not.

Fatty Acid Synthesis and Metabolism in Cancer Cells

Information on fatty acid synthesis and metabolism in cancer cells. Learn how proliferatively active cells require fatty acids for functions such as membrane generation, protein modification, and bioenergetic requirements. These fatty acids are derived either from dietary sources or are synthesized by the cell.
