What enzymes are used to break down carbohydrates while complex carbohydrates require enzymes such as salivary amylase, pancreatic amylase and maltose for digestion although fiber resists enzyme action and is not broken down during digestion, break down of starch by enzymes starts in. High endogenous salivary amylase activity is olism of starch in contrast, pancreatic amylase, produced by the gene amy2, has not undergone similar genetic repetition (15) even though the vast majority of starch digestion occurs in the small intestine via pancreatic amylase (16.

Process of digestion of carbohydrates in the gastrointestinal tract: mouth, stomach, small intestine, duodenum, ileum enzymes, salivary, pancreatic amylase. Pancreatic amylase proteins are very similar (47) salivary amylase initiates carbohydrate digestion the rate of starch digestion also depends on the structure of the starch which can be affected by storage or cooking (13. What is amylase concentration in saliva and in the juices formed by the pancreas the function of amylase is to break starches into smaller molecules as part of the process of digestion so does the rate of starch digestion, until the amylase concentration reaches a certain.
