Efficiency of vitamin B3
Summary: Few verify the human body will lack and is suffused with the acid, because it exists in the general food extensively, but some examples reveal: It will cause --Have a headache, vomit and muscle ache, renal gland function enough and fails, the hair whitens, the skin is covered with wrinkles, it is easy and tired to fall in a swoon etc..
It suffused with acids to be coenzyme of coenzyme A, coenzyme A to suffused with sour and 3 - the intersection of phosphoric acid and adenosine, compound member that pyrophosphate combine - second amine of sulfhydryl- with, so the function of coenzyme A is suffused with the physiological function of the acid.
(1)Fatty acid is formated, coenzyme A binds in the small intestine wall with second acid and produces COA-S-AC, change third two the intersection of acyl and coenzyme A into, turn into long the intersection of chain and fatty acid with another activatory the intersection of fatty acid and function and then through the intersection of biotin and catalysis of enzyme;
(2)Fatty acid is degraded, participate in fatty acid and degrade and release the supersession course of a large amount of energy;
(3)Citric acid cycle, is suffused with the acid to participate in in circulation from man ketone two acid and salt synthetic citric acid, and a - ketoacid go the carboxyl oxidize, react; (4)Choline acetylation, COA-S-AC transmits acetyl group to choline to turn into acetyl choline --A kind of nerve impulse conducts the material;
(5)The antibody is synthetic, suffused with the formation that the acid can promote those antibodies with resistance;
(6)The use of the nutrient, because of the function of coenzyme A, are suffused with absorption and use that the sour existence is favorable to various nutriment. Can keep the skin healthy and maintain the blood circulation, contribute to normal operation of the nervous system.
