Folate is the natural form of vitamin B9, essential for DNA synthesis and genetic integrity.
Folate is the naturally occurring form of vitamin B9, a water-soluble vitamin essential for one-carbon metabolism, DNA synthesis, and cell division. It is found naturally in foods and is the precursor to the active coenzyme tetrahydrofolate (THF).
Folate functions as the precursor to tetrahydrofolate (THF), the active coenzyme form that serves as a carrier of one-carbon units in numerous biosynthetic reactions. These reactions are fundamental to the synthesis of purines and pyrimidines, the nitrogenous bases of DNA and RNA, making folate essential for all forms of cell division and tissue growth. Folate also plays a crucial role in homocysteine metabolism, participating in the remethylation of homocysteine to methionine, an important amino acid for protein synthesis and methylation reactions. Adequate folate status is particularly important during pregnancy to prevent neural tube defects and support fetal development. The body stores folate primarily in the liver, but storage capacity is limited, requiring consistent dietary intake. Natural folate is somewhat heat-labile and can be partially lost during cooking and food processing. The term "folate" specifically refers to naturally occurring forms, while "folic acid" refers to the synthetic form used in supplements and fortified foods.
Essential coenzyme for one-carbon metabolism, DNA and RNA synthesis, and normal cell division.
Daily requirements are 400 μg DFE for adults; consume a variety of folate-rich vegetables and legumes, using light cooking methods to preserve content. Women planning pregnancy should prioritize folate-rich foods or supplements.
Folate is indispensable for DNA synthesis, cell division, and the prevention of birth defects.
