Character description

White crystal or crystalline powder, without special odor, soluble in water and pyridine, water solubility: 680 g/L (25 C); slightly soluble in glycerol and alcohol. Galactose is a monosaccharide composed of six carbon and one aldehyde, which is classified as aldose and hexose. D- galactose and L- galactose exist naturally. The general structure of D- galactose as part of lactose found in milk, lactose in milk by the human body is decomposed into glucose and galactose was absorbed by.
