 用作医药原料及食品添加剂

生化试剂。丙酮酸钠(113-24-6)用于测定乳酸,脱氢酶的底物;也是良好的健身减肥膳食补充剂;广泛用于食品、化妆品中。

丙酮酸钠可以作为细胞培养中的替代碳源。尽管细胞更倾向于以葡萄糖作为碳源,但是,如果没有葡萄糖的话,细胞也可以代谢丙酮酸钠。

测定乳酸脱氢酶的底物,测定人体血液中谷-丙转氨酶(G.P.T)或谷-草转氨酶(G.O.T)含量的试剂。医药原料及食品添加剂

Sodium pyruvate is utilized as a component in culture broth and media. It is utilized by cells as an intermediate compound in the metabolism of carbohydrates, proteins, and fats. It is involved with amino acid metabolism and initiates the Kreb′s cycle. In thiamine deficiency, its oxidation is retarded and it accumulates in the tissues, especially in nervous structures. A protcol that uses sodium pyruvate to establish stably transfected human B cell lines has been published. The 100 mM solution should be diluted 1:100 for most cell culture applications.

Intermediate in sugar metabolism and in enzymatic carbohydrate degradation (alcoholic fermentation) where it is converted to acetaldehyde and CO2 by carboxylase. In muscle, Pyruvic acid (derived from glycogen) is reduced to lactic acid during exertion, which is reoxidized and partially retransformed to glycogen during rest. The liver can convert Pyruvic acid to alanine by amination. A diagnostic agent for Parkinson disease
