      <description>Dihydrofolic acid, a product of the folate biosynthesis pathway, can be metabolized by multiple enzymes. 
Dihydrofolic acid can be reduced by a NADP-driven dihydrofolate reductase resulting in a NADPH, hydrogen ion and folic acid. 
Dihydrofolic acid can also be reduced by an NADPH-driven dihydrofolate reductase resulting in a NADP and a tetrahydrofolic acid. Folic acid can also produce a tetrahydrofolic acid through a NADPH-driven dihydrofolate reductase. 
Dihydrofolic acid also interacts with 5-thymidylic acid through a thymidylate synthase resulting in the release of dUMP and 5,10-methylene-THF
Tetrahydrofolic acid can be converted into 5,10-methylene-THF through two different reversible reactions.
Tetrahydrofolic acid interacts with a S-Aminomethyldihydrolipoylprotein through a aminomethyltransferase resulting in the release of ammonia, a dihydrolipoylprotein and 5,10-Methylene-THF
Tetrahydrofolic acid interacts with L-serine through a glycine hydroxymethyltransferase resulting in a glycine, water and 5,10-Methylene-THF.
The compound 5,10-methylene-THF reacts with an NADPH dependent methylenetetrahydrofolate reductase [NAD(P)H] resulting in NADP and 5-Methyltetrahydrofolic acid. This compound interacts with homocysteine through a methionine synthase resulting in L-methionine and tetrahydrofolic acid.
Tetrahydrofolic acid can be metabolized into 10-formyltetrahydrofolate through 4 different enzymes:

1.- Tetrahydrofolic acid interacts with FAICAR through a phosphoribosylaminoimidazolecarboxamide formyltransferase resulting in a 1-(5'-Phosphoribosyl)-5-amino-4-imidazolecarboxamide and a 10-formyltetrahydrofolate
2.-Tetrahydrofolic acid interacts with 5'-Phosphoribosyl-N-formylglycinamide through a phosphoribosylglycinamide formyltransferase 2 resulting in a Glycineamideribotide and a 10-formyltetrahydrofolate
3.-Tetrahydrofolic acid interacts with Formic acid through a formyltetrahydrofolate hydrolase resulting in water and a 10-formyltetrahydrofolate
4.-Tetrahydrofolic acid interacts with  N-formylmethionyl-tRNA(fMet) through a 10-formyltetrahydrofolate:L-methionyl-tRNA(fMet) N-formyltransferase resulting in a L-methionyl-tRNA(Met) and a 10-formyltetrahydrofolate

10-formyltetrahydrofolate can interact with a hydrogen ion through a bifunctional 5,10-methylene-tetrahydrofolate dehydrogenase resulting in water and 
5,10-methenyltetrahydrofolic acid.
 
Tetrahydrofolic acid can be metabolized into 5,10-methenyltetrahydrofolic acid  by reacting with a 
5'-phosphoribosyl-a-N-formylglycineamidine through a phosphoribosylglycinamide formyltransferase 2 resulting in water, glycineamideribotide and  5,10-methenyltetrahydrofolic acid. The latter compound can either interact with water through an aminomethyltransferase resulting in a N5-Formyl-THF, or it can interact with a NADPH driven bifunctional 5,10-methylene-tetrahydrofolate dehydrogenase resulting in a NADP and 5,10-Methylene THF.
