IUPAC 名称
(2R,3S,4S,5R,6R)-6-({[({[(2R,3S,4R,5R)-5-(2,4-dioxo-1,2,3,4-tetrahydropyrimidin-1-yl)-3,4-dihydroxyoxolan-2-yl]methoxy}(hydroxy)phosphoryl)oxy](hydroxy)phosphoryl}oxy)-3,4,5-trihydroxyoxane-2-carboxylic acid
描述
UDP-L-iduronate is converted from UDP-n-glucuronic acid. n-Iduronic and n-glucuronic acid have been identified as the hexuronic acid components of dermatan sulfate. UDP-Dglucose is the metabolic precursor of both uranic acids . Conversion of UDP-u-glucose to UDP-n-glucuronic acid and the subsequent C-5 inversion of UDP-n-glucuronic acid to UDP-Liduronic acid is catalyzed by extracts of mammalian tissues. However, UDP-n-iduronic acid has never been isolated and its role in the polymerization of L-iduronic acid-containing polymers has remained hypothetical. [HMDB]
