Dihydrofolic acid (conjugate base dihydrofolate) (DHF) is a folic acid (vitamin B9) derivative which is converted to tetrahydrofolic acid by dihydrofolate reductase. Since tetrahydrofolate is needed to make both purines and pyrimidines, which are building blocks of DNA and RNA, dihydrofolate reductase is targeted by various drugs to prevent nucleic acid synthesis.

WebDec 21, 2024 · Folate is a generic term that typically refers to a group of water-soluble compounds that play an essential role in deoxyribonucleic acid (DNA) biosynthesis. [1] It is also known as vitamin B9 and is different from folinic acid or leucovorin, more technically known as 5-formyltetrahydrofolate (5-FTHF). Folic acid is the synthetic form of folate. WebOnce the folates pass through the FOLR genes (folate receptor genes), folates get converted to Dihydrofolate (DHF) via the DHFR genes (in Red) above. In addition, the gene DHFR, which is part of the folate family of genes (MTHFR), is directly connected to the folate receptor, that feeds the biopterin cycle in your brain.
