描述
Erythrono-1,4-lactone has been identified as a lactone of tetronic acid in the urine from normal adults and neonates. The formation of this compound may be a consequence of lactonization of erythronic acid during the extraction/isolation process. Lactonization is a potential problem when measuring acids that contain a hydroxyl group at the number 4 carbon, as lactones are formed under acidic conditions. Evidence indicates that most 4-hydroxy acids do not normally exist to any appreciable extent as lactones in urine. (PMID 1192581). [HMDB]
