Vitamine B3 (aside nikotine/Niacin) CAS: 59-67-6

Niacin ikoreshwa cyane mu nyongeramusaruro z'imirire n'imiti ikoreshwa mu mirire kugira ngo ishyigikire ubuzima bw'umutima n'imitsi, imikorere y'ibinure mu mubiri, n'imikorere y'imitsi muri rusange. Nk'intangiriro ya coenzymes nicotinamide adenine dinucleotide (NAD) na nicotinamide adenine dinucleotide phosphate (NADP), niacin igira uruhare mu bikorwa byinshi byo guhindura imikorere y'imirire, ifasha mu guhindura intungamubiri mo ingufu no kugira uruhare mu guhumeka kw'uturemangingo no gukora ATP. Kubwibyo, ishyirwa mu nganda zigamije ubuzima bw'umutima, gucunga cholesterol, no gukora ingufu. Uretse uruhare rwayo mu mikorere y'ingufu, niacin yamenyekanye kubera ubushobozi bwayo bwo gushyigikira imiterere myiza y'ibinure mu gutuma urugero rwa cholesterol rungana. Ikoreshwa mu nyongeramusaruro z'imirire zigenewe gukemura ibibazo byihariye by'umutima n'imitsi bifitanye isano n'imikorere y'ibinure mu mubiri, nko gushyigikira urugero rwiza rwa triglyceride no kunoza ingano ya cholesterol mu mubiri. Byongeye kandi, niacin ikoreshwa mu nganda zikora imiti kubera inyungu zayo mu guhangana n'ibibazo byihariye by'ubuzima, harimo na pellagra n'izindi ndwara ziterwa n'ibinure mu mubiri. Ikoreshwa ryayo mu gutegura imiti rishobora kuba rikubiyemo kuvura ikibazo cyo kubura niacin no gucunga ibinure byinshi mu mubiri binyuze mu buyobozi bw'abaganga. Byongeye kandi, niacin ikoreshwa mu nganda z'ibiribwa mu rwego rwo kongera intungamubiri mu biribwa bitandukanye, bigafasha mu bikorwa by'ubuzima rusange bigamije kugabanya ibura ry'intungamubiri. Kwinjira kwayo mu biribwa bikungahaye ku gutanga vitamine B z'ingenzi ku baturage bafite ibyago byo kutarya niacin bihagije, bityo bigatuma intungamubiri zihagije kandi zikagira ubuzima bwiza. Muri rusange, uburyo niacin ikoreshwa mu buryo butandukanye mu nyongeramusaruro, mu kongera intungamubiri, no mu miti bigaragaza akamaro kayo nk'intungamubiri y'ibanze ishyigikira ubuzima bw'umutima n'imitsi, imikorere y'imikorere y'umubiri, n'imibereho myiza muri rusange ishingiye ku bumenyi bwa siyansi n'imikorere y'inganda.
