Methionine and serine formation in control and mutant human cultured fibroblasts: evidence for methyl trapping and characterization of remethylation defects. Folic acid vs. Methylfolate Three misleading information to be clarified: 1.Supplemental Methylfolate*is natural. Young ruminants without a fully functional rumen require folic acid supplementation of milk replacer. In turn, tetrahydrofolate serves as the carrier of various one-carbon groups that are added to, or abstracted from, metabolites such as histidine, serine, methionine, purines, and thymidylate. Aljassim N, Alfadhel M, Nashabat M, Eyaid W. Mol Genet Metab Rep. 2020 Sep 2;25:100644. doi: 10.1016/j.ymgmr.2020.100644. Also folic acid requirements within species have been shown to differ between genotypes (Solis et al., 2008). Eur J Pediatr. But even folic acid must first be converted in the body into the active form of folate-5-MTHF, so that it can be used by our cells.

NLM Although the most conspicuous symptom of folic acid deficiency is pernicius anemia, it has been observed that the lack of folate intake during the pregnancy induce the incidence … Global efforts include programs and partnerships worldwide, from Asia to Europe to Africa, and extensive work in human rights using geospatial technology to corroborate abuses. Folinic acid also appears to be a more metabolically active form of folate, capable of boosting levels of the coenzyme forms of the vitamin in circumstances where folic acid has little to no effect. Folic acid is essential to having enough dihydrofolate reductase to regenerate NADH from its oxidative form. elevated level of folic acid (2) and its coenzyme forms (3), has been found to characterize at least one type of abnor-malgrowth, namely that of the leukemic white cell. Annual Review of Biochemistry Vol. doi: 10.1007/pl00014306.
