5,10-Methylenetetrahydrofolate (5,10-CH₂-THF) is the substrate used by the enzyme methylenetetrahydrofolate reductase (MTHFR)^[1][2] to generate 5-methyltetrahydrofolate (5-MTHF, or levomefolic acid).

5,10-CH₂-THF can also be used as a coenzyme in the biosynthesis of thymidine. To be specific, it is the C1-donor in the reactions catalyzed by thymidylate synthase and thymidylate synthase (FAD). It also acts as a cofactor in the synthesis of serine from glycine via the enzyme serine hydroxymethyl transferase.

MTHFR metabolism: folate cycle, methionine cycle, trans-sulfuration and hyperhomocysteinemia. 5-MTHF: 5-methyltetrahydrofolate; 5,10-methyltetrahydrofolate; BAX: Bcl-2-associated X protein; BHMT: betaine-homocysteine S-methyltransferase; CBS: cystathionine beta synthase; CGL: cystathionine gamma-lyase; DHF: dihydrofolate (vitamin B9); DMG: dimethylglycine; dTMP: thymidine monophosphate; dUMP: deoxyuridine monophosphate; FAD⁺ flavine adenine dicucleotide; FTHF: 10-formyltetrahydrofolate; MS: methionine synthase; MTHFR: mehtylenetetrahydrofolate reductase; SAH: S-adenosyl-L-homocysteine; SAME: S-adenosyl-L-methionine; THF: tetrahydrofolate.
