In this ppt the viewer will able to know about DIASTASE Enzyme. It is an amylolytic enzymes present in the saliva (salivary diastase or ptyalin and pancreatic diastase or amylopsin) found in the digestive tract of animals and also in malt extract. Diastase hydrolyses starch, glycogen and dextrin to form in all three instances glucose, maltose, and the limit-dextrin. Salivary amylase is known as ptyalin; although humans have this enzyme in their saliva, some mammals, such as horses, dogs, and cats, do not. Ptyalin begins polysaccharide digestion in the mouth; the process is completed in the small intestine by the pancreatic amylase, sometimes called amylopsin. The amylase of malt digests barley starch to the disaccharides that are attacked by yeast in the fermentation process. Portion explained: 1. Biological Source of Diastase Enzyme 2.
