Yet, if you have access to foods rich in Vitamin B-1, your chances of developing beriberi are low. Meat, dairy products, and whole grains are all excellent sources of Vitamin B-1 that can prevent you from getting the disease. Genetic beriberi is a rare condition that prevents the body from absorbing Vitamin B-1. 2  Pregnant women and anyone with hyperthyroidism (over-active thyroid gland) need extra vitamin B-1.
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.
From Wikipedia, the free encyclopedia. An amylase (/ËÃ¦máµ»leÉªs/) is an enzyme that catalyses the hydrolysis of starch into sugars. Amylase is present in the saliva of humans and some other mammals, where it begins the chemical process of digestion. Foods that contain large amounts of starch but little sugar, such as rice and potatoes, may acquire a slightly sweet taste as they are chewed because amylase degrades some of their starch into sugar.
