Lactose is a disaccharide, molecular formula is C12H22O11, is in the mammalian milk disaccharides, hence the name. Its molecular structure is composed of a molecule of glucose and galactose condensation to form a molecule. Tiny sweet taste. Lactose is a kind of disaccharides, English name is Lactose; By a molecular beta - D - galactose and an alpha - D - glucose in beta 1, 4 - a glycosidic bond. Molecular formula C12H22O11 and molecular weight of 342.3 grams. There are two types of end group isomer: alpha and beta lactose lactose, in water solution can be transformed each other. Alpha lactose easily combined with a molecular crystal water.
Sweetness is about one 6 of the sucrose, the solid components in 2-8% lactose in milk. Young mammals gut can secrete lactase lactose as monosaccharides. Adult animals, including in addition to the Caucasian race most of the human body the activity of the enzyme lactase is reduced greatly. Therefore, drinking milk can produce symptoms such as diarrhea, abdominal distension, called lactose intolerance.
