개요
Oxaloacetic acid is an α-keto acid and a key component of cellular metabolism in its conjugate base form, oxaloacetate. Oxaloacetate reacts with acetyl-coenzyme A (acetyl-CoA; ) and water to form citrate in the first step of the citric acid cycle and is regenerated by oxidation of L-malate in the final step. It is an intermediate in gluconeogenesis that is formed in mitochondria via carboxylation of pyruvate and subsequently decarboxylated and phosphorylated to form phosphoenolpyruvate. It can be converted to aspartate via addition of an amino group from glutamate. Oxaloacetate (30 μmol/min per 100 g for 30 minutes, i.v.) reduces blood glutamate levels, severity of neurological dysfunction, and brain edema in a rat model of closed head injury.화학적 성질
off-white crystals용도
A four carbon dicarboxylic acid that is an intermediate in the citric acid cycle and glucogenesis. It has been shown to inhibit succinate dehydrogenase.정의
ChEBI: An oxodicarboxylic acid that is succinic acid bearing a single oxo group.일반 설명
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.Purification Methods
Crystallise it from boiling EtOAc, or from hot Me2CO/hot *C6H6. [Beilstein 3 IV 1808.]옥살아세트산 준비 용품 및 원자재
