Name three disaccharides.
Maltose, Sucrose, Lactose
Maltose has _____(number) ________(alpha or beta) glucose molecules.
Has a _______ glycosidic linkage.
Sucrose is made of up 1 _________ and 1 _________ molecule.
Has a _________ glycosidic linkage.
Lactose is made up of 1 ________ molecule and 1 __________ molecule.
Explain lactose intolerance.
