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.
ââAlpha-Amylase (or Î±-Amylase) is a digestive enzyme that hydrolyses alpha-1,4 bonds of large polysaccharides such as starch and glycogen, yielding the smaller by-products of glucose and maltose. (1) Alpha amylase is synthesized in the acinar cells of the saliva glands and stored in secretory granules inside the cells. (2) Its release from the salivary cells is greatly increased in response to taste or chewing motions of the jaw.
