Document Summary
Carbonyl group found at end of molecule (aldose) or within carbon chain (ketone) Different arrangement of hydroxyl groups; different function. Sugars normally form rings, not linear chains in aqueous solutions. Carbon-1 in linear chain forms bond with oxygen on carbon-5. Hydroxyl group then forms from the former carbonyl of c-1. Carbon-1 in linear chain forms bond with oxygen and hydroxyl group. New hydroxyl on carbon-1 either below plane of ring or above. Polysaccharide: polymers of monosaccharides through condensation between two. Display important information, act as signage on outer surface of plasma membrane. Glycoprotein: protein bonded to carbohydrate on cell surface, function as cell-cell. Disaccharide: simplest polysaccharide formed of two sugars. Joined by -linkages: readily hydrolyze to release glucose, resulting in production of chemical energy. Phosphorylase: enzyme that catalyzes hydrolysis of -glycosidic linkages in. Amylase: enzyme that catalyzes hydrolysis of -glycosidic linkages in starch.
