Why is maltose a carbohydrate?


Wiki User

Maltose is a disaccharide formed by two molecules of glucose, and glucose is a carbohydrate monosaccharide (hence its 1:2:1 cardon to hydrogen to oxygen ratio). The formula for maltose is C12H22O11 and is not C12H24O12 because in formation of the maltose, dehydration synthesis occurs and a water (H2O) molecule is formed by being taken out in order to bond the two glucose molecules, so don't let its chemical formula not being in the ratio 1:2:1 make you think it's not a carbohydrate, because that's the ratio for monosaccharides (single saccharide carbs).
