Hydantoin, or glycolylurea, is a heterocyclic organic compound with the formula CH 2 C(O)NHC(O)NH.It is a colorless solid that arises from the reaction of glycolic acid and urea. It is an oxidized derivative of imidazolidine.In a more general sense, hydantoins can refer to a groups and a class of compounds with the same ring structure as the parent. For example, phenytoin (mentioned below) has two phenyl groups substituted onto the number 5 carbon in a hydantoin molecule.t is an oxidized derivative of imidazolidine.

The pH range of the mouth is 5.6-6.9 slightly acidic, and the average body temp is 37 deg C-this is the environment in which human amylase is most active.
Human body as a complex doesn't have short pH level interval. There are enormous difference among pH of different organs. Blood's average pH is 7,35-7,45, stomach's pH is 1,5-2, small intestine's pHÂ¨is alkaline, large intestine's pH is acidic (6 and lower).est Answer: The normal pH of blood running through arteries (large elastic-walled blood vessels that carry blood from the heart to other parts of the body) is 7.4; the pH of blood in the veins (vessels that transports blood to the heart) is about 7.35.
