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

Sucrose: glucose and fructose

Explanation:

What monosaccharides will result from the hydrolysis of sucrose?

Sucrose is a disaccharide composed of 2 different monosaccharides: glucose and fructose joining by a 1 ⇒ 2 bond. These monosaccharides will be released upon the hydrolysis of sucrose.

What monosaccharide will result from the hydrolysis of starch?

Starch is a polysaccharide composed of numerous glucose monomers joined by glycosidic bonds (1 ⇒ 4 and 1 ⇒ 6). These monosaccharides will be released upon the hydrolysis of starch.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
