The physiological function of vitamin M

Also known as folic acid, anti-anemia; to maintain normal cell growth and function of the immune system to prevent fetal malformation. By MTX, the combination of amino benzoic acid and glutamic acid rich in green leaf vegetables in the name suggests. Folic acid is a yellow crystalline, slightly soluble in water, in acidic solution unstable and susceptible to light damage. Food stored at room temperature, which contain folic acid also easily lost. Folic acid in the body into tetrahydrofolate, which is the coenzyme of many kinds of enzymes. Tetrahydrofolate to pass a carbon-based groups in the compounds, the exchange between such a carbon-based groups, including methyl (-CH3), hydroxymethyl (-C Geu OH), methoxy (-OCH3), imine formyl (-CO-NH). Conversion of a carbon-based group is choline, serine, histidine, DNA and other necessary steps during biosynthesis. A lack of folic acid the human body mainly neutropenia, larger volume of red blood cells occurred giant cell anemia. Leaves the number of neutrophils is not a sub-normal average of 2 ~ 3 leaves, but leaves more than 5 white blood cell count increased significantly. Human intestinal bacteria can synthesize folic acid, so in general less prone to deficiency diseases. But when the absorption, metabolism disorders or organizational requirements, as well as long-term use of excessive intestinal inhibitory drugs (such as sulfa), etc. may apply to cause folic acid deficiency. The human body needs about 400 micrograms per day.
