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 a normal person at rest, an oral clinical temperature of 98.6Â° F or 37Â° C. Actual normal temperatures may range a fraction of a degree or increments of a whole degree higher or lower because of effects of sleep, exercise, eating, sleeping, metabolism, and the ambient temperature.he normal oral temperature is 37Â° Celsius (98.6Â° Fahrenheit); rectally, it is 37.3Â° Celsius (99.2Â° Fahrenheit). The tympanic membrane temperature is a direct reflection of the body's core temperature.
