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.
Amylase is an example of an enzyme. Amylase is found in our saliva and is responsible for starting to break down the starch that we eat. So amylase is an enzyme that carries out the specific reaction of breaking down starch into a simple sugar.An enzyme breaks down larger molecules into smaller molecules like sugars. -An enzyme is specific for its substrate: the enzyme that breaks down starch won't be able to break proteins down. -An enzyme is reusable, it doesn't get used up in the reaction, so it can perform it over and over again.
