Folic acid is a water-soluble vitamin with the molecular formula C19H19N7O6. It is also called pteroylglutamic acid because of its rich content in green leaves. There are several forms in nature, and the parent compound is composed of pteridine, p-aminobenzoic acid and glutamic acid.
Folic acid is a derivative of pteridine. It was originally isolated from the liver. Later, it was found that the green leaves of plants are very rich, so it is called folic acid. It widely exists in meat, fresh fruits and vegetables. It is a yellow crystalline powder, tasteless and odorless. Its sodium salt is easily soluble in water, insoluble in alcohol, ether and other organic solvents, insoluble in cold water but slightly soluble in hot water. It is unstable in acid solution and easy to be destroyed by light. Also known as "vitamin Bc" and "vitamin M". A B vitamin. Yellow or orange flake or needle shaped crystals, odorless and tasteless, heated to about 250 ºC, the color gradually darkens, and finally becomes a black colloidal substance. Anti anemia drug, the content in tea is up to 50~70 μ G/100g, which can promote the formation of normal red blood cells. It is involved in the transport of methyl group in the metabolism of tea plants. It also participates in the synthesis of amino acids and nucleic acids in the body, and promotes the formation of red blood cells together with vitamin B12. It is used for various megaloblastic anemia, especially for pregnant women and infants. Human intestinal bacteria can synthesize folic acid, so it is not easy to lack. Folic acid deficiency can be caused by malabsorption, metabolic disorder or long-term use of intestinal antibacterial drugs. In addition, folic acid is also widely found in animal and plant foods, including viscera, eggs, fish, pears, broad beans, beets, spinach, cauliflower, celery, lettuce, citrus, nuts and beans. The daily intake of folic acid is maintained at 3.1 μ When g/kg, the body can have adequate folic acid reserves; The total daily folic acid intake of pregnant women should be more than 350 μ g; The safe intake of infants by kg is similar to that of adults, i.e. 3.6 per day μ G/kg can meet the needs of growth and maintenance of normal hemogram.
