D-Lactose monohydrate Chemical Properties,Usage,Production

Description

D-Lactose monohydrate is a type of lactose. D-Lactose is composed of D-galactose and D-glucose. D-Lactose monohydrate can be used as sweetener or excipient.

Chemical Properties

white or cream powder

Uses

mosquito-repellent

Uses

[a]22 +52.4°, c = 4.5 in H2O

Uses

D-Lactose monohydrate can be used as chromatographic adsorbent.

Definition

ChEBI: Alpha-lactose monohydrate is a glycoside.

General Description

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

Biochem/physiol Actions

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.
