Mu rugendo rwo gukurikirana ubuzima no gutinda gusaza, ubushakashatsi bwa siyansi burigihe butuzanira ibyiringiro bishya nibishoboka. Mu myaka yashize, NMN (Nicotinamide Mononucleotide), ibintu byitwa bioaktique bizwi cyane, yagiye buhoro buhoro mu bantu kandi ikurura abantu benshi. Ni ubuhe buryo? Kandi ni ukubera iki yashyizeho umwete mu rwego rwubuzima? Reka twinjire mu mayobera ya NMN hamwe.
NMN ni iki?
NMN, aribyo Nicotinamide Mononucleotide, ni molekile isanzwe ibaho mubuzima bwose. Mu mubiri w'umuntu, NMN ni intangiriro y'ibanze ya synthesis ya coenzyme I (NAD +). Coenzyme I (NAD +) igira uruhare runini muburyo bwo guhinduranya ibintu muri selile kandi ikagira uruhare runini mugukomeza imirimo isanzwe nubuzima bwimikorere. Uko abantu basaza, urwego rwa NAD + mu mubiri wumuntu rugenda rugabanuka buhoro buhoro, bikaba bivugwa ko bifitanye isano rya bugufi nimpinduka nyinshi zifatika zijyanye no gusaza no kubaho no gutera indwara. Kwiyongera hamwe na NMN birashobora kongera neza ibiri muri NAD + mumubiri, bityo bigatanga imbaraga zihagije kumikorere isanzwe ya selile kandi bigafasha kugumana ubuzima bwubusore bwumubiri.
Principle Ihame ryakazi rya NMN
Uburyo bwibikorwa bya NMN ahanini buzenguruka hejuru yuburebure bwa NAD +. Iyo turya NMN, ihita yinjira mumubiri igahinduka NAD + munsi yuruhererekane rwimisemburo. Nka coenzyme ya enzymes nyinshi zingenzi, NAD + igira uruhare mubikorwa byingenzi bya physiologique mungirangingo, nka metabolism yingufu, gusana ADN, no kugenzura imvugo ya gene. Kubijyanye ningufu za metabolism, NAD + igira uruhare mugikorwa cyo guhumeka selile, ifasha mitochondriya guhindura intungamubiri muri ATP, molekile yingufu ingirabuzimafatizo zishobora gukoresha mu buryo butaziguye. Urwego rwa NAD + ruhagije rugira uruhare mu kunoza imikorere no gukora neza ya mitochondriya, bitanga ingufu nyinshi mu ngirabuzimafatizo kandi bikadushoboza kugira imbaraga nyinshi nubuzima. Mu rwego rwo gusana ADN, NAD + ni substrate yingenzi kumuryango wa PARP (Poly ADP - Ribose Polymerase). Iyo selile zangijwe nimirasire ya ultraviolet, stress ya okiside, nibindi, enzymes za PARP zirakora kandi zigakoresha NAD + muguhuza PAR (Poly ADP - Ribose), hanyuma ugashaka proteine zijyanye no gusana ADN yangiritse. Kugumana urwego rwo hejuru rwa NAD + birashobora kongera ibikorwa byimisemburo ya PARP, kwihutisha gahunda yo gusana ADN, kugabanya ikwirakwizwa ry’imiterere ya gene no kwangirika kw ingirabuzimafatizo, kandi bigafasha kwirinda indwara ziterwa no gusaza - indwara zifitanye isano. Mubyongeyeho, NAD + nayo igira uruhare mukugenzura umuryango wa poroteyine ya Sirtuins. Poroteyine za Sirtuins zigira uruhare runini mu gusaza kwa selile, kugenzura metabolike, ibisubizo bitera umuriro, n'ibindi. Nka coenzyme ya Sirtuins, NAD + irashobora gukora poroteyine za Sirtuins, igenga imiterere ya gene, kandi ikagira ingaruka ku mikorere ya physiologique no kubaho kwa selile. Mu kuzuza NMN kugirango yongere urwego rwa NAD +, irashobora gukora mu buryo butaziguye poroteyine za Sirtuins no gukora imirimo nko gutinda gusaza kwa selile no kunoza imikorere ya metabolike.
● Ingaruka za NMN
1 Gutinda umusaza
Inzira yo gusaza iherekejwe no kugabanuka gahoro gahoro imikorere yingingo zitandukanye na sisitemu mumubiri. NMN idindiza gusaza kurwego rwa selire binyuze munzira nyinshi nko kongera urwego rwa NAD +, kunoza imikorere ya mito-iyambere, kongera ubushobozi bwo gusana ADN, no gukora proteine za Sirtuins. Ubushakashatsi bwerekana ko kuzuza hamwe na NMN bishobora guteza imbere cyane imikorere yumubiri yinyamaswa zigerageza, nko kongera imbaraga zimitsi, kunoza kwihanganira imyitozo, no kongera imikorere yubwenge, bigatuma bagaragara kandi bakitwara muburyo buto. Ku bantu, kuzuza igihe kirekire hamwe na NMN biteganijwe kandi ko bidindiza gusaza kwuruhu, kugabanya isura yiminkanyari hamwe nu mwanya wimyaka, kuzamura ireme ryibitotsi, no kuzamura urwego rwubuzima rusange rwumubiri, bikadufasha gukomeza ubwiza nubuzima.
2 ： Kongera ubudahangarwa
NMN ifite ingaruka nziza zo kugenzura imikorere yumubiri. Ku ruhande rumwe, irashobora guteza imbere ikwirakwizwa no gutandukanya ingirangingo z'umubiri, kongera ibikorwa by'uturemangingo, no kunoza ubushobozi bw'umubiri bwo guhangana. Ku rundi ruhande, NMN ifasha kugumana imikorere isanzwe ya mitochondriya mu ngirabuzimafatizo z'umubiri, itanga imbaraga zihagije mu bikorwa by'uturemangingo. Mu kuzuza NMN, dushobora kongera ubudahangarwa bwacu, kugabanya ibyago byindwara, kandi tugahangana neza n’ibibazo by’ibidukikije.
3：Kunoza imikorere ya metabolike
Imikorere mibi ya metabolike niyo ntandaro yindwara nyinshi zidakira, nkumubyibuho ukabije, diyabete, indwara zifata umutima, nibindi. NMN irashobora kunoza imikorere ya metabolike igenga inzira ya metabolike muri selile. Ubushakashatsi bwerekanye ko kuzuza NMN bishobora kongera insuline, bigatera gufata no gukoresha glucose, kandi bigafasha gukomeza isukari mu maraso. Muri icyo gihe, NMN irashobora kandi kongera metabolisme y’ibinure, kugabanya ikwirakwizwa ry’amavuta mu mubiri, kandi ikagira uruhare runini mu gukumira no kuzamura umubyibuho ukabije. Byongeye kandi, NMN igira ingaruka zo gukingira sisitemu yumutima. Irashobora kugabanya urugero rwamaraso ya lipide, kunoza imikorere ya endoteliyale yimitsi, no kugabanya ibyago byindwara zifata umutima. Kubantu bahangayikishijwe nubuzima bwa metabolike, NMN ntagushidikanya ko ari intungamubiri zifite agaciro gashoboka.
4：Kunoza imikorere yubwenge
Hamwe no gukura kwimyaka, imikorere yubwonko igenda igabanuka buhoro buhoro, kugabanuka kwibukwa, indwara zubwenge nibindi bibazo bigenda bitera ibibazo abasaza. NMN yerekanye ibisubizo bitanga umusaruro mugutezimbere imikorere yubwenge.
