Activity c: hydrolysis of carbohydrates as discussed earlier, disaccharides are composed of two monosaccharides linked together. polysaccharides are long chains of monosaccharides. the bonds joining these subunits can be broken in a process called hydrolysis. in this procedure, you will hydrolyze sucrose and starch by heating them with acid. what monosaccharides will result from the hydrolysis of sucrose? what monosaccharide will result from the hydrolysis of starch? the hydrolysis reactions will be carried out in two large test tubes. as figure 3 shows, one contains sucrose and hydrochloric acid (hci) and the
