Lactose - Wikipedia
网页The molecular structure of α-lactose, as determined by X-ray crystallography. Lactose crystals, viewed under polarized light. Lactose is a disaccharide composed of galactose and glucose, which form a β-1→4 glycosidic linkage. Its systematic name is β-D-galactopyranosyl-(1→4)-D-glucose.

网页2009年1月1日 · α-Lactose crystallizes as a monohydrate while β-lactose forms anhydrous crystals; thus, the yield of α-lactose is ∼5% higher than that of β-lactose. When milk or whey is spray-dried, any lactose which has not been pre-crystallized forms an amorphous glass which is stable if the moisture content of the powder is maintained low.
