I am not sure how much detail you need, but I have attached a list of some helpful references and links. The references can be found via PubMed.

In general, proteases, lipases, and amylases are proteins that are very important for digestion. Proteases are enzymes that break bonds between individual amino acids, thus breaking down proteins. Lipases break down fats into fatty acids and monoglycerides. Activity of lipases is enhanced by bile secretion. Lipases are active at water/lipid interfaces. Amylases is the main type of enzyme that breaks down complex polysacchrides into sugar units like maltose and glucose. ...
