中文百科

乳糖

乳糖英语:Lactose)是一种双糖,由一分子β-D-半乳糖和一分子β-D-葡萄糖在β-1,4-位形成糖苷键相连。分子式C12H22O11(Jmol立体图),摩尔质量342.3克。有两种端基异构体:α-乳糖和β-乳糖,在水溶液中可互相转化。α-乳糖很容易结合一分子结晶水。

成年动物若长期持续饮用乳品(初期以少量多次慢饮为宜),也可刺激肠道内乳糖酶的活性并增加一定数量,虽活性和数量不如幼儿时期,但仍能有效帮助分解乳糖。

Lactose 乳糖

The molecular structure of α-lactose, as determined by X-ray crystallography.
Molécula de lactosa, descompuesta mediante la hidrólisis en glucosa (2) y galactosa (1).

Lactose is a disaccharide sugar derived from galactose and glucose that is found in milk. Lactose makes up around 2–8% of milk (by weight), although the amount varies among species and individuals, and milk with a reduced amount of lactose also exists. It is extracted from sweet or sour whey. The name comes from lac (gen. lactis), the Latin word for milk, plus the -ose ending used to name sugars. It has a formula of C12H22O11 and the hydrate formula C12H22O11·H2O, making it an isomer of sucrose.
