Lactosenoun

(carbohydrate) The disaccharide sugar of milk and dairy products, C12H22O11, a product of glucose and galactose used as a food and in medicinal compounds.

Melibiosenoun

(carbohydrate) A disaccharide consisting of glucose and galactose residues

Lactosenoun

The main sugar present in milk, called also sugar of milk or milk sugar. When isolated pure it is obtained crystalline; it is separable from the whey by evaporation and crystallization. It is a disaccharide with the formula C12H22O11, being chemically 4-(

Melibiose

Melibiose is a reducing disaccharide formed by an α-1,6 linkage between galactose and glucose (D-Gal-α(1→6)-D-Glc). It differs from lactose in the chirality of the carbon where the galactose ring is closed and that the galactose is linked to a different point on the glucose moiety.
