Descrizione

Applicazioni

D-Lactose is a disaccharide of D-glucose and D-galactose units found as a major sugar in milk. D-Lactose is used for the culture of lactic acid metabolizing bacteria, lactic acid bacteria. D-Lactose is used to identify and characterized galectins.

Azioni biochim/fisiol

Lactose is a dissacharide formed by the condensation of one galactose and one glucose molecule. Lactose is the major sugar in the milk of most species, typically present between 2-8%. The enzyme lactase hydrolyzes lactose to its constituent monosaccharides. In neonates, glucose released via the action of lactase is a major energy source.
