一般說明

草酰乙酸是一种二羧酸。它是柠檬酸循环中的一个中间体。它高度溶于水，并且大量存在。它通过丙酮酸羧化酶对丙酮酸的作用，在线粒体中产生。草酰乙酸的分解产物包括苹果酸、丙酮酸和天冬氨酸。

應用

草酰乙酸已被用作测定胞质杂合体和神经母细胞瘤细胞中柠檬酸合酶活性的底物。它也已被用于测定苹果酸脱氢酶的活化。

生化／生理作用

草酰乙酸是三羧酸循环的一个中间体，对新陈代谢至关重要。它是糖异生途径的一部分。丙酮酸羧化酶的突变会导致草酰乙酸的产生减少。它可抑制琥珀酸脱氢酶，是线粒体代谢的一种关键调节剂。

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.
