Final answer:
Pancreatic amylase is the enzyme secreted by the pancreas that breaks down starch into disaccharides like maltose during digestion in the small intestine.
Step-by-step explanation:
The pancreatic secretion that digests starch into disaccharides is pancreatic amylase. This enzyme is responsible for breaking down both cooked and uncooked starch, as well as glycogen, into smaller sugar units like erythro-dextrin, achro-dextrin, and maltose. Specifically, pancreatic amylase acts on the α-1→ 4 glycosidic linkages found in these carbohydrates, converting them into disaccharides such as maltose, which are then further digested by other enzymes like maltase present in the small intestine.
