All Aboard â The Digestive Process Starts in the Mouth. Digestive enzymes dwell in our mouth, where our saliva, containing an enzyme called amylase, acts as a catalyst in breaking down food and begins the process of digestion. This enzyme, also found in the pancreas, starts breaking down starches, or complex carbohydrates, into simple sugars.
Four of the enzymes have special importance in digestion of food by humans. 1  Amylase from our salivary glands and pancreas digests starch to maltose in our mouth and small intestine. 2  Lipase from the pancreas digests lipids to fatty acids and glycerol in our small intestine. Pepsin is a protease that begins digestion of proteins, breaking them into peptides and amino acids. Pepsinogen, is secreted by gastric glands of the stomach into the stomach.
