0 引 言有机酸是结肠中细菌酵解的主要产物。主要是碳水化合物的发酵产物。其主要功能是为氧化代谢和结肠粘膜细胞的离子泵供能。D ,L 乳酸是不饱和非挥发的三碳原子羧酸 ,它也是细菌酵解产物 ,正常情况下不进入循环系统而被饱和成短链脂肪酸。然而 ,当细菌酵解增加 ,缺氧
0 Introduction Organic acids are the major product of bacterial fermentation in the colon. Mainly carbohydrate fermentation products. Its main function is to supply energy to the ion pump that oxidizes metabolism and colonic mucosal cells. D, L Lactic acid is an unsaturated non-volatile three-carbon atom carboxylic acid, which is also a bacterial digestion product that normally saturates into short-chain fatty acids without entering the circulatory system. However, when bacterial digestion increases, hypoxia
