2-O-Methylascorbic acid (2-O-MA) is a derivative of vitamin C (ascorbic acid). The enzyme catechol-O-methyltransferase catalyzes the methylation of L-ascorbic acid into 2-O-methylascorbic acid (PMID: 7129800). 2-O-Methylascorbic acid belongs to the class of organic compounds known as butenolides. These are dihydrofurans with a carbonyl group at the C2 carbon atom. 2-O-Methylascorbic acid has been identified in urine and was found to be higher in older women than in younger women (PMID: 28813537).
