Biological functions of allantoin

Biology Bulletin, 2006
A historical review of allantoin research is presented. An increased allantoin level in the trophoblast and serum of pregnant women has been demonstrated. Allantoin concentration decreased in placental tissues and increased in the serum in developing placental insufficiency.

Enzymic Racemization of Allantoin

The Journal of Biochemistry, 1978
Allantoin racemase was isolated from cells of Candida utilis, and purified by chromatography on columns of DEAE-cellulose and Sephadex G-100. Using this purified enzyme, the racemization of allantoin in deuterium oxide was investigated. Polarimetric and PMR spectroscopic analyses showed that racemization of allantoin by the enzyme proceeded in ...

Allantoin as a Vitamin

Doklady Biochemistry and Biophysics, 2004
Inactivation of the gene ( Uox ) in primates, which is responsible for the synthesis of theenzyme urikase, has determined new ways of social and intellectual evolution of mammals [1, 2]. Almost simultaneously with this process, a mutation occurred, as a result of which primates lacked the capability of endogenous synthesis of ascorbate. These mutations
