Definition Glucose Galactose Sucrose Term List three examples of disaccharides. Definition Maltose Lactose Sucrose Term List three examples of polysaccharides. Definition Starch Glycogen Cellulose Term What is the function of glucose, lactose and glycogen in animals? Definition Glucose: fuel for cell respiration Lactose: solutes in milk Glycogen: stores glucose in liver and muscles Term What is the function of fructose, sucrose and cellulose in plants? Definition Fructose: sweetener in fruit Sucrose: transported from leaves to other parts by vascular tissue Cellulose: primary component of cell walls Term Hydrolysis of a disaccharide to two monosaccharides. Definition lactose + water -> glucose + galactose Term Hydrolysis of a polysaccharide to many monosaccharides Definition starch + (many) water -> (many) glucose Term Hydrolysis of a tiglyceride lipid to glycerol and fatty acids Definition triglyceride + 3 water -> glygerol + 3 fatty acids Term Hydrolysis of a protein to amino acids Definition protein + (many) water -> (many) amino acids Term Hydrolysis v Condensation Definition Hydrolysis: smaller reactants and water yeild larger molecules; digestion Condensation: re-form larger molecules; water molecule(s) and smaller molecule are produced Term Function of Lipids Definition -energy storage -thermal insulation -phospholipids make up the double layer of all cell membranes Term How do carbohydrates and lipids differ in terms of energy storage? Definition Lipids store twice as much energy.
