B. Monosaccharide 1. Simple sugars 2. Soluble in water 3. Sweet 4. Forms crystals 5. Most important in nutrition are those with 5 or 6 carbons - the pentoses and the hexoses (ose=sugar)

C. Disaccharides 1. Two simple sugars coupled by removing water 2. Four common disaccarhides: Sucrose = Glucose + Fructose Maltose = Glucose +Glucose Lactose = Glucose + Galactose Cellobiose = Glucose +Glucose

D. Polysaccharides 1. Long chains of sugar molecules 2. Some common polysaccharides are: A. Starch 1. Amylose - unbranched 2. Amylopectin - branched N(maltose) a 1-4 linkage 24-30 glucose per non reducing end group. 50,000-400,000 Daltons.
