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.
The normal pH value for the body fluids is between pH 7.35 and 7.45. When the pH value of body fluids is below 7.35, the condition is called acidosis, and when the pH is above 7.45, it is called alkalosis. Metabolism produces acidic products that lower the pH of the body fluids.
