Other Molecules having Coenzyme Function: These include lipoic acid (thioctic acid), biotin, tetrahydrofolic acid and cobalamine. Sulfonamides, which include sulfamethoxazole, or SMX, sulfisoxazole, and sulfadiazine, inhibit bacterial DNA production by binding to dihydropteroate synthetase, or DHPS, in … It gets this carbon atom by sequestering formaldehyde produced in other processes. Glucarpidase: The serum concentration of the active metabolites of (6S)-5,6,7,8-tetrahydrofolic acid can be reduced when (6S)-5,6,7,8-tetrahydrofolic acid is used in combination with Glucarpidase resulting in a loss in efficacy. Mechanism of action. (6S)-5,6,7,8-tetrahydrofolic acid is a derivative of folic acid in which the pteridine ring is fully reduced; it is the parent compound of a variety of coenzymes that serve as carriers of one-carbon groups in metabolic reactions. tetrahydrofolic acid: see coenzyme coenzyme, any one of a group of relatively small organic molecules required for the catalytic function of certain enzymes. Folinic acid is a 5-formyl derivative of tetrahydrofolic acid. lyze the reaction of tetrahydrofolic acid with formaldehyde by nucleophilic catalysis by a pathway which must involve the intermediate formation of cationic imines. It serves in one carbon reductions reactions. You will receive the quantity as you ordered as solvent-free form. Ingredient Type: Vitamin Also Known As: Folinic Acid, Calcium folinate, Leucovorin 5-formyl tetrahydrofolate, aka Folinic Acid, is the natural, active coenzyme form of folate. Detailed Folic Acid dosage information for adults and children. This is accomplished by folic acid reductase enzyme that needs NADPH + H + (reduced Co II) as a hydrogen donor. Structure: Biological function: Folic acid, in the form of tetrahydrofolic acid, functions as a coenzyme for those reactions effecting the transfer of one-carbon units (ie. acid.
