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.
A normal temperature measured by mouth is 98.6 degrees Fahrenheit (37 degrees Celsius) and can be between 97 degrees Fahrenheit to 99 degrees Fahrenheit (36.1 degrees Celsius to 37.2 degrees Celsius).This is because different people have different normal body temperatures.
