Common Name

(S)(+)-Allantoin

Description

Allantoin is a chemical compound with formula C4H6N4O3. It is also called 5-ureidohydantoin, glyoxyldiureide, and 5-ureidohydantoin. It is a product of oxidation of uric acid. It is a diureide of glyoxylic acid. (Wikipedia) In E. coli K-12, the enzyme allantoinase (EC 3.5.2.5) catalyzes the conversion of (S)(+)-Allantoin to Allantoate (KEGG).
