Uses	A disaccharide sugar present in milk.
Uses	Lactose is a disaccharide carbohydrate that occurs in mammalian milk except that of the whale and the hippopotamus. it is princi- pally obtained as a cows’ milk derivative. it is also termed milk sugar and it is a reducing sugar consisting of glucose and galactose. its most common commercial form is alpha-monohydrate, with the beta-anhydride form available to a lesser extent. all forms in solution will equilibrate to a beta:alpha ratio of 62.25:37.75 at 0°c. it is about one-sixth as sweet as sugar and is less soluble. it functions as a flow agent, humectant, crystallization control agent, and sweetener. it is used in baked goods for flavor, browning, and tenderizing and in dry mixes as an anticaking agent.
Uses	D-Lactose is used for the culture of lactic acid metabolizing bacteria, lactic acid bacteria. D-Lactose is used to identify and characterized galectins.
