概要

α-Lactose is the primary sugar present in milk and the main energy source to a newborn mammalian through its mother's milk. It is digested by the intestinal lactase (EC 3.2.1.108), an enzyme expressed in newborns. The enzyme's activity declines following weaning which can lead to lactose intolerance in adult mammals.

生化学的・生理学的メカニズム

Lactose is a disaccharide formed by the condensation of one galactose and one glucose molecule. Lactose is the predominant sugar in the milk of most species, usually at between 2-8%. Lactase hydrolyzes lactose into its constituent monosaccharides. In neon
