Identification
Name:Folic acid
Description:Folic acid is a member of the vitamin B family. Folic acid, being biochemically inactive, is converted to tetrahydrofolic acid and methyltetrahydrofolate by dihydrofolate reductase. These folic acid congeners are transported across cells by receptor-mediated endocytosis, synthesize purine and thymidylate nucleic acids, interconvert amino acids, methylated tRNA, and generate and use formate.
