                                                                Anhydroleucovorin, also known as 5,10-Methenyltetrahydrofolate (5,10-CH=THF),  is a form of tetrahydrofolate that is an intermediate in metabolism. 5,10-CH=THF is a coenzyme that accepts and donates methenyl (CH=) groups. It is produced from 5,10-methylenetetrahydrofolate by either a NAD+ dependent methylenetetrahydrofolate dehydrogenase, or a NADP+ dependent dehydrogenase. It can also be produced as an intermediate in histidine catabolism, by formiminotransferase cyclodeaminase, from 5-formiminotetrahydrofolate. 5,10-CH=THF is a substrate for methenyltetrahydrofolate cyclohydrolase, which converts it into 10-formyltetrahydrofolate.
