Amylase is an enzyme that has the ability to break down starch, a polysaccharide, into smaller disaccharides. in the last project, you saw that two types of amylase function in the human digestive system, salivary amylase and pancreatic amylase. salivary amylase and pancreatic amylase are released by two accessory organs of the digestive system. in what structures do the enzymes actually chemically digest food?
