Starch is composed of glucose monomers that humans can digest while cellulose is composed of sucralose units that humans cannot digest. e.) Humans have the enzyme to hydrolyze alpha sugar linkages found in starch but not the beta sugar linkages found in cellulose.

e.) Humans have the enzyme to hydrolyze alpha sugar linkages found in starch but not the beta sugar linkages found in cellulose.
