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 average normal body temperature for children is about 37Â°C (98.6Â°F). A child's temperature usually averages from around 36.3Â°C (97.4Â°F) in the morning to 37.6Â°C (99.6Â°F) in the afternoon. What is the Normal Body Temperature for Adults? Temperature in the mouth (oral) is about 36.8Â°C (98.2Â°F) Temperature under the arm (axillary) is about 36.5Â°C (97.7Â°F) Temperature in the anus (rectum/rectal), vagina, or in the ear (otic) is about 37.5Â°C (99.5Â°F)
