A disaccharide which on hydrolysis yields glucose and galactose .
其中产糖一葡萄糖和乳糖水解.
Disaccharide : any of a class of carbohydrates , including lactose and sucrose , that yield two monosaccharides upon hydrolysis .
双糖：碳水化合物的一种，包括乳糖和蔗糖，在水解下可生成两个单糖。
Plants protect the reactive monosaccharides for transport and storage by condensing them with loss of water , into less reactive sugars , e. g. , d-glucose and d-fructose , are condensing in such a way that their reactive functions are lost to form the disaccharide no reducing sugar , sucrose .
