一般描述
α-酮戊二酸(αKG)是三羧酸 (TCA)/Krebs循环中的琥珀酰辅酶 A 和异柠檬酸之间重要的中间产物。
应用
α--酮戊二酸已用于：
- 作为最低基础培养基α (α-MEM)的补充剂，培养原代间充质基质细胞/干细胞 (MSC)， 以研究其对年龄相关性骨质疏松症的影响
- 化学治疗，以在手动和自动寿命机器 (ALM) 平台之间，比较几种化合物对寿命的治疗效果
- 用作打印趋化因子配体，使用高通量技术筛选趋化因子受体并验证与表面等离子体共振 (SPR) 的相互作用
生化/生理作用
α-酮戊二酸(αKG)是一种氮清除剂，是谷氨酸和谷氨酰胺的重要来源。它负责控制ATP合成并减少三羧酸 (TCA) 循环中的等价物 (NAD+/NADH) 生成。它可促进蛋白质合成，防止肌肉中的蛋白质降解。这种免疫营养因子参与一般免疫和胶原蛋白代谢。在老年啮齿动物中，αKG可加速骨缺损愈合，可能具有潜在抗衰老作用。这种Krebs循环分子可用作昆虫和哺乳动物细胞培养的补充剂。

Quantification of 2-ketoglutaric acid in plasma and cerebrospinal fluid as its O-trimethylsilyl++-quinoxalinol derivative by gas chromatography chemical ionization mass spectrometry is described with benzoylformic acid as internal standard. This technique, with ammonia as reactant gas, only detects the protonated molecular

Hypoxia-inducible factor (HIF) prolyl hydroxylases (PHDs) are α-ketoglutarate (αKG)-dependent dioxygenases that function as cellular oxygen sensors. However, PHD activity also depends on factors other than oxygen, especially αKG, a key metabolic compound closely linked to amino-acid metabolism. We examined the
