实验方案

Folic acid or folate is classified as a B vitamin (B9). Folic acid is synthetically produced, and used in fortified foods and supplements. Folate is converted by humans to dihydrofolate (dihydrofolic acid), tetrahydrofolate (tetrahydrofolic acid), and other derivatives, which have various biological activities.
