乳糖(lactose)作为哺乳动物乳汁中的一种重要营养成分,经乳糖酶分解后消化吸收,参与组织细胞的生命活动,在人类健康和营养方面发挥重要功能.由于乳糖酶(lactase,LCT)缺乏所导致的乳糖不耐受是一种常见的临床症状,在中国人群中的发生频率很高.目前其发生机制尚未阐明,大部分研究认为乳糖酶基因及其上游的一些多态位点与不同地区的发病密切相关.

Lactose is an important nutrition element in the milk of mammals,and the digestion of lactose depends on the participation of lactase.Lactose plays an important role in maintaining nutrition and health in the process of human life.But in most humans,the lactase activity declines after weaning.After milk consumption,some people have a series of clinical symptoms,which is called adult-type lactase intolerance.So far the mechanisms of lactose intolerance have not been clarified,while it has been reported that some polymorphism sites of LCT are associated with the disease.
