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.And when the body is in good working order, human blood reveals a narrow pH window of about 7.35â7.45 (slightly alkaline).or instance, healthy human skin has an approximate pH of 5.5 (slightly acidic).
