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.

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

Chemiluminescence of Lucigenin–Allantoin and Its Application for the Detection of Allantoin

Analytical Chemistry, 2017
Allantoin has been reported as a promising biomarker for monitoring of oxidative stress in humans and widely utilized in a variety of topical pharmaceuticals and cosmetics. Currently, the detection of allantoin is achieved by using chromatographic coupled techniques, which needs sample pre-extraction, derivatization, complex matrixes, and expensive ...

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 ...

Urate to allantoin, specifically (S)-allantoin

Nature Chemical Biology, 2006
Enzymes that catalyze the formation of (S)-allantoin from the product of the urate oxidase reaction have been identified. This finding answers the longstanding question of how living organisms produce a single enantiomer of allantoin.
