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.
