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.
For instance, healthy human skin has an approximate pH of 5.5 (slightly acidic). Saliva, on the other hand, has a pH of around 6.5â7.4 (teetering on either side of neutral). Your digestive tractâs pH can range from 1.5 to 7.0, depending on what stage of digestion is underway.
