Common NameD-Maltose
DescriptionMaltose, or malt sugar, is a primary disaccharide in the human diet formed from two units of glucose joined with an alpha (1->4) linkage. It is the second member of an important biochemical series of glucose chains. The addition of another glucose unit yields maltotriose, Further additions will produce dextrins, also called maltodextrins, and eventually starch. Maltose can be broken down into two glucose molecules by hydrolysis in living organisms. At the surface of the small intestine, the brush border enzymes maltase, breaks down maltose.

General function:
Involved in catalytic activity
Specific function:
May serve as an alternate pathway for starch digestion when luminal alpha-amylase activity is reduced because of immaturity or malnutrition. May play a unique role in the digestion of malted dietary oligosaccharides used in food manufacturing.
