Amylase digests carbohydrates,
lipase digests fats, and trypsin digests proteins
. The pancreas also secretes large amounts of sodium bicarbonate, which protects the duodenum by neutralizing the acid that comes from the stomach.

to hydrolyze the glycosidic bonds in starch molecules, converting complex carbohydrates to simple sugars
. There are three main classes of amylase enzymes; Alpha-, beta- and gamma-amylase, and each act on different parts of the carbohydrate molecule.
What is the function of pepsin?
An enzyme made in the stomach that
breaks down proteins in food during digestion
. Stomach acid changes a protein called pepsinogen into pepsin.
Which gland produces amylase?
In the human body, amylase is predominantly produced by
the salivary glands and the pancreas
