Folic acid CAS 59-30-3 is a water-soluble vitamin with the molecular formula C19H19N7O6. It is named after its abundant content in green leaves, also known as pteroylglutamic acid. There are several forms of existence in nature, and their parent compounds are formed by combining three components: pteridine, p-aminobenzoic acid, and glutamic acid.

Folic acid contains one or more glutamyl groups, and most naturally occurring folic acid is in the form of polyglutamic acid. The bioactive form of folic acid is tetrahydrofolate. Folic acid is a yellow crystal that is slightly soluble in water, but its sodium salt is highly soluble in water. Insoluble in ethanol. It is easily damaged in acidic solutions and unstable to heat. It is easily lost at room temperature and easily damaged when exposed to light.

Folic acid can be actively absorbed and passively absorbed through diffusion in the body, with the absorption site mainly located in the upper part of the small intestine. The absorption rate of reducing folic acid is higher, and the more glutamine groups there are, the lower the absorption rate. Glucose and vitamin C can promote absorption. After absorption, folic acid is stored in tissues such as the intestinal wall, liver, and bone marrow in the body. With the participation of NADPH, it is reduced by folate reductase to tetrahydrofolate (THFA or FH4) with physiological activity, which is involved in the synthesis of purines and pyrimidines. Therefore, folic acid plays an important role in protein synthesis and cell division and growth, promoting the formation of normal red blood cells. When lacking, it can cause a decrease in hemoglobin production in red blood cells and hinder cell maturation, leading to megaloblastic anemia.
