Salivary amylase (ptyalin) Amylase is found in saliva and breaks starch into maltose and dextrin. This form of amylase is also called ptyalin /ËtaÉªÉlÉªn/ It will break large, insoluble starch molecules into soluble starches (amylodextrin, erythrodextrin, and achrodextrin) producing successively smaller starches and ultimately maltose.
Alpha-Amylase in Saliva. Alpha-amylase is found in saliva. As soon as you eat starch, your saliva glands secrete this enzyme into your mouth. In fact, even the thought or smell of food can cause you to salivate. Alpha-amylase in saliva digests starch into pairs of glucose molecules, which are smaller, sweeter sugars.That's why starchy carbohydrates taste sweeter the longer they are in your mouth.lpha-amylase in saliva digests starch into pairs of glucose molecules, which are smaller, sweeter sugars.
