| Common Name | 5,10-Methenyltetrahydrofolic acid |
|---|
| Description | 5,10-Methenyltetrahydrofolic acid, also known as anhydro-leucovorin or 5,10-methenyl-THF, belongs to the class of organic compounds known as tetrahydrofolic acids. These are heterocyclic compounds based on the 5,6,7,8-tetrahydropteroic acid skeleton conjugated with at least one L-glutamic acid unit. It can also be produced as an intermediate in histidine catabolism, by formiminotransferase cyclodeaminase, from 5-formiminotetrahydrofolate.5,10-CHTHF is a substrate for methenyltetrahydrofolate cyclohydrolase, which converts it into 10-formyltetrahydrofolate. 5,10-Methenyltetrahydrofolic acid is a moderately basic compound (based on its pKa). 5,10-Methenyltetrahydrofolic acid exists in all living species, ranging from bacteria to humans. Click on genes, proteins and metabolites below to link to respective articles. Within humans, 5,10-methenyltetrahydrofolic acid participates in a number of enzymatic reactions. In particular, 5,10-methenyltetrahydrofolic acid can be biosynthesized from 10-formyltetrahydrofolate through the action of the enzyme C-1-tetrahydrofolate synthase, cytoplasmic. In addition, 5,10-methenyltetrahydrofolic acid can be biosynthesized from N5-formyl-THF; which is mediated by the enzyme 5-formyltetrahydrofolate cyclo-ligase. In humans, 5,10-methenyltetrahydrofolic acid is involved in the metabolic disorder called the methylenetetrahydrofolate reductase deficiency (mthfrd) pathway. It is produced from 5,10-methylenetetrahydrofolate by either a NAD+ dependent methylenetetrahydrofolate dehydrogenase, or a NADP+ dependent dehydrogenase. 5,10-Methenyltetrahydrofolate (5,10-CHTHF) is a form of tetrahydrofolate that is an intermediate in metabolism. 5,10-CHTHF is a coenzyme that accepts and donates methenyl (CH) groups. 5,10-Methenyltetrahydrofolic acid is expected to be in Cannabis as all living plants are known to produce and metabolize it. |
