Description générale

Oxaloacetic acid is a dicarboxylic acid. It is an intermediate in the citric acid cycle. It is highly soluble in water and is present ubiquitously. It is produced in the mitochondria by the action of pyruvate carboxylase on pyruvate. Breakdown products of oxaloacetate includes malate, pyruvate and aspartic acid.

Application

Oxaloacetic acid has been used as a substrate for measuring citrate synthase activity in cybrids and neuroblastoma cells. It has also been used for measuring malate dehydrogenase reactivation.

Actions biochimiques/physiologiques

Oxaloacetic acid being an intermediate in the tri carboxylic cycle is central to metabolism. It is part of gluconeogenesis pathway. Mutation in pyruvate carboxylase leads to decreased production of oxaloacetate. It inhibits succinate dehydrogenase and is a key regulator of mitochondrial metabolism.

Monosaccharide Biosynthesis

Learn about monosaccharide biosynthesis and the metabolism of monosaccharides. A unit of a carbohydrate and the simplest form of a sugar, a monosaccharide cannot be hydrolyzed into a simpler compound.

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.

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.
