What are the different enzymes needed in digestion of foods?
The glands that act first are in the mouth—the salivary glands. Saliva produced by these glands contains an enzyme- amylase that begins to digest the starch from food into smaller molecules. The next set of digestive glands is in the stomach lining. They produce stomach acid and an enzyme that digests protein – pepsin, geletinase,gastric amylase, gastric lipase. One of the unsolved puzzles of the digestive system is why the acid juice of the stomach does not dissolve the tissue of the stomach itself. In most people, the stomach mucosa is able to resist the juice, although food and other tissues of the body cannot. After the stomach empties the food and juice mixture into the small intestine, the juices of two other digestive organs mix with the food to continue the process of digestion. One of these organs is the pancreas. It produces a juice that contains a wide array of enzymes to break down the carbohydrate, fat, and protein in food – trypsin,sucrase, maltase, isomaltase, lactase, i
