简介编辑
α-酮戊二酸(英语:α-Ketoglutaric acid)是戊二酸的两种带酮基的衍生物中的一种(如果不特别说明,“酮戊二酸”这个术语大多数指的就α型。β-酮戊二酸只是酮基的位置不同而已,并且不太常用)白色细结晶性粉末。熔点113.5℃。易溶于水、醇、极难溶于醚,久贮变淡灰黄色,易潮解。 [1]
这种物质的阴离子,α-酮戊二酸盐是一种重要的生物化合物。它是谷氨酸脱氨基的酮酸产物,并且是三羧酸循环的中间产物。 [2]
功能编辑
三羧酸循环
α-酮戊二酸是微生物三羧酸循环中重要的代谢中间产物,是连接细胞内碳-氮代谢的关键节点,在循环中的位置位于异柠檬酸之后以及琥珀酰辅酶A之前。在这一部位,回补反应可以通过自谷氨酸的转氨基作用产生α-酮戊二酸而达到补充此中间代谢产物的目的,通过谷氨酸脱氢酶作用于谷氨酸也可以达到这一目的。 [2]
生成氨基酸
谷氨酸在谷氨酰胺合酶的作用下可以生成谷氨酰胺,此酶使用一分子ATP以产生谷氨酰磷酸盐;这一中间产物被作为亲核试剂的氨攻击,从而形成谷氨酰胺与无机磷酸。 [3]
膳食补充品
α-酮戊二酸作为膳食补充品出售,商品名为AKG或a-KG,卖给健身爱好者或健美运动员,销售方声称这种物质可以提高训练顶峰时的表现。销售方声称这是基于“研究表明过多的氨可以结合到α-酮戊二酸上被带走以减少氨中毒带来的众多问题”。然而,表现出α-酮戊二酸可以减少氨中毒有效的唯一研究仅仅用于已进行血液透析的患者。 [4]

Introduction to edit
Alpha ketone glutaric acid (English: alpha Ketoglutaric acid) are two kinds of glutaric acid with ketone group of derivatives of a (if not specified otherwise, the term "ketone glutaric acid" most refers to the type of alpha. Beta - ketone glutaric acid just different from the location of the keto group, and less commonly used) white crystalline powder. The melting temperature of 113.5 ℃. Soluble in water, alcohol, extremely difficult to soluble in ether, long storage become yellow light gray, easy deliquescence. [1]
The substance of the anion, alpha ketone glutaric acid salt is a kind of important biological compounds. It is the keto acid production of glutamate deamination, and the product is in the middle of the tricarboxylic acid cycle. [2]
Function to edit
The Krebs cycle
Alpha ketone glutaric acid is important in the Krebs cycle as A metabolic intermediate, is the key to connect the carbon - nitrogen metabolism in cells nodes, place in the circle in the isocitrate after and before succinyl coa. In this place, covering the reaction can be created by transamination of glutamic acid from alpha ketone glutaric acid, and achieve the goal that complement the intermediate metabolites by glutamate dehydrogenase in glutamic acid can also achieve this goal. [2]
Generate amino acids
Glutamic acid in glutamine synthase can be generated under the action of glutamine, which USES a ATP molecules to produce a glutamine phosphate; This intermediate was used as a nucleophilic reagent ammonia attack, forming a glutamine and inorganic phosphate. [3]
Dietary supplements
Alpha ketone glutaric acid sold as a dietary supplement, called AKG or a - KG goods, sold to bodybuilders or bodybuilder, sellers claim that this kind of material can improve the performance of training the peak. Sellers claim that this is based on "the research shows that excess ammonia can be combined to alpha ketone glutarate was taken on to reduce many of the problems of ammonia poisoning".
