说明

D-半乳糖是一种醛缩己糖，是一种天然存在于体内的还原糖。它存在于乳制品和一些水果如李子、樱桃和猕猴桃的果胶中。D-半乳糖也存在于某些蔬菜、栗子和一些草药中。

一般描述

D-galactose, an aldohexose, is a reducing sugar found naturally in the body. It is present in dairy products and the pectin of some fruits like plums, cherries, and kiwi. D-galactose is also found in certain vegetables, chestnuts, and some herbs.
 

应用

D-(+)-Galactose has been used:
  • as a supplement in SGal media to grow yeast strains to examine the role of different Ssa heat-shock proteins (Hsp70) isoforms in Hsp90 chaperoning functions
  • as a carbon source in Biolog (MT2) microplate assay to test the ability of isolates to utilize carbon substrates
  • to induce expression of membrane protein-green fluorescent protein (GFP) fusion in yeast

生化/生理作用

半乳糖是一种简单的单糖，可作为能量来源，也是糖脂和糖蛋白的必需成分。半乳糖被Leloir途径的酶转化为葡萄糖，从而能够促进能量代谢。缺乏编码这些蛋白质的基因，将导致代谢功能紊乱疾病半乳糖血症。
Metabolism of D-galactose leads to the formation of reactive oxygen species (ROS) and results in oxidative stress and hepatocyte damage.
