Impamvu Alpha Ketoglutarate Magnesium ari ingenzi ku buzima bwawe

Kalisiyumu Alpha ketoglutarate (AKG) ni metabolite iri hagati y’uruhererekane rw’aside tricarboxylic kandi igira uruhare mu gukora aside amine, vitamine na aside organic ndetse no mu ihinduka ry’ingufu. Ishobora gukoreshwa nk'inyongera mu mirire kandi ifite amahirwe menshi yo gukoreshwa. Uretse imikorere yayo mu mubiri w’umuntu, kalisiyumu alpha-ketoglutarate inakoreshwa cyane mu rwego rw’imiti kandi yabaye igice cy’ingenzi cy’ibicuruzwa byinshi by’ubuzima n’ibisubizo by’ubuvuzi.

Alpha-ketoglutarate ni iki?

AKG ni metabolite isanzwe ibaho mu buryo busanzwe, ikaba ari igice cya Krebs cycle, bivuze ko imibiri yacu ubwayo iyikora. Inganda zikora kandi verisiyo y’ubukorano isa na AKG ikorwa mu buryo busanzwe.

AKG ikora iki?

AKG ni molekile ikora mu buryo bwinshi bwa metabolisme n'uturemangingo. Ikora nk'umutanga ingufu, ibanziriza ikorwa rya aside amine n'uturemangingo, kandi ihindura imikorere ya epigenetic. Ni molekile y'ingenzi mu mikorere ya Krebs, igenzura umuvuduko rusange w'imikorere ya aside citric mu mubiri. Ikora mu buryo butandukanye mu mubiri kugira ngo ifashe kubaka imitsi no gufasha mu gukira kw'ibikomere, ari na imwe mu mpamvu ikunzwe cyane mu isi y'imitsi.

AKG kandi ikora nk'umuti ugabanya azote, ikarinda azote kwiyongera cyane kandi ikarinda kwiyongera kwa ammonia nyinshi. Ni isoko nziza ya glutamate na glutamine, bitera imbaraga mu gukora poroteyine mu mitsi kandi bikabuza kwangirika kwa poroteyine.

Byongeye kandi, igenzura enzyme ya 10-11 translocation (TET) ikora mu gukuraho ADN na lysine demethylase irimo Jumonji C domain, ari nayo histone demethylase ikomeye. Muri ubu buryo, ni ingenzi mu kugenzura no kugaragaza imiterere y’uturemangingo.

Ese AKG ishobora gutinza gusaza?

Hari ibimenyetso bigaragaza ko AKG ishobora kugira ingaruka ku busaza, kandi ubushakashatsi bwinshi bwerekana ko ari ko bimeze. Ubushakashatsi bwakozwe mu 2014 bwagaragaje ko AKG yongereye igihe cyo kubaho cy'abantu bakuru bakuze C. elegans ku kigero cya 50% binyuze mu gukumira ATP synthase na target ya rapamycin (TOR).

Muri ubu bushakashatsi, twasanze AKG idakomeza igihe cyo kubaho gusa ahubwo inatinza imiterere imwe n'imwe ijyanye n'imyaka, nko gutakaza ingendo zihuse z'umubiri zisanzwe ku bantu bakuze ba C. elegans. Kugira ngo dusobanukirwe uburyo AKG igira ingaruka ku gusaza, tuzasobanura uburyo AKG ikoresha mu gukumira ATP synthase na TOR kugira ngo yongere igihe cyo kubaho muri C. elegans ndetse n'ubundi bwoko.

Uburyo kalisiyumu alpha-ketoglutarate ikora

Ubwa mbere, kalisiyumu alpha-ketoglutarate igira uruhare runini mu mikorere y’ingufu. Nk’umusaruro w’igice cy’ingenzi cya aside tricarboxylic (TCA cycle), kalisiyumu α-ketoglutarate igira uruhare mu ikorwa ry’ingufu mu ngirabuzima fatizo. Binyuze muri TCA cycle, intungamubiri nka karubohidrati, ibinure, na poroteyine zirahinduka oxidation zikanabora kugira ngo habeho ATP (adenosine triphosphate) kugira ngo itange ingufu ku turemangingo. Nk’igice cy’ingenzi mu mikorere ya TCA, kalisiyumu α-ketoglutarate ishobora guteza imbere imikorere y’ingufu mu turemangingo, kongera ingufu z’umubiri, gufasha kongera imbaraga z’umubiri no kwihangana, no kunoza umunaniro w’umubiri.

Icya kabiri, kalisiyumu α-ketoglutarate igira uruhare runini mu mikorere y’aside amine. Aside amine ni ingenzi muri poroteyine, naho kalisiyumu α-ketoglutarate igira uruhare mu guhindura no gutunganya aside amine. Mu gihe cyo guhindura aside amine mo izindi metabolites, kalisiyumu α-ketoglutarate ihinduranya aside amine kugira ngo ikore aside amine nshya cyangwa aside α-keto, bityo ikagenzura uburinganire n’ikoreshwa rya aside amine. Byongeye kandi, kalisiyumu α-ketoglutarate ishobora kandi gukora nk'ishingiro rya okiside kuri aside amine, ikagira uruhare mu mikorere y’aside amine, kandi igatanga ingufu na dioxyde de carbone. Kubwibyo, kalisiyumu α-ketoglutarate ifite akamaro kanini mu kubungabunga homeostasis ya aside amine na metabolite de poroteyine mu mubiri.

Byongeye kandi, kalisiyumu alpha-ketoglutarate ikora nk'umusemburo urwanya udukoko twinshi kandi ukarinda uturemangingo kwangirika kwa ogisijeni. Muri icyo gihe, kalisiyumu α-ketoglutarate ishobora kandi kugenzura imikorere y'ubudahangarwa bw'umubiri, igatuma uturemangingo tw'ubudahangarwa bw'umubiri dukora neza, kandi ikarushaho kurwanya indwara n'ubwandu. Kubwibyo, kalisiyumu α-ketoglutarate ifite akamaro kanini mu kubungabunga ubudahangarwa bw'umubiri no kurwanya indwara.

Ubushakashatsi ku ngaruka za kalisiyumu α-ketoglutarate ku gusaza

Gusaza bitugiraho ingaruka twese kandi ni ikintu gitera indwara nyinshi, kandi dukurikije imiterere y’inganda zikora Medicare, amahirwe yo kurwara agenda yiyongera uko imyaka igenda ishira.

Kalisiyumu alpha-ketoglutarate ni metabolite y'ingenzi mu mubiri wacu, izwiho uruhare rw'uturemangingo mu mizunguruko ya Krebs, uruziga rw'ingenzi mu gutuma aside ibinure na aside amine bitunganywa, bigatuma mitochondria ikora ATP (ATP ni isoko y'ingufu z'uturemangingo).

Bikubiyemo gushyiramo calcium alpha-ketoglutarate, bityo calcium alpha-ketoglutarate ishobora no guhinduka glutamate hanyuma ikavamo glutamine, ishobora gufasha mu gutera imbaraga poroteyine na kolajeni (collagen ni poroteyine ya A igizwe na 1/3 cya poroteyine zose mu mubiri kandi igafasha mu kubungabunga ubuzima bw'amagufwa, uruhu n'imitsi).

Kalisiyumu α-ketoglutarate, nk'inyongeramusaruro y'intungamubiri nyinshi, ifite amahirwe menshi yo gukoreshwa mu bicuruzwa by'ubuvuzi. Imirimo yayo itandukanye ya biyolojiya nko kurwanya antioxidant, kurwanya gusaza, kugenzura ubudahangarwa bw'umubiri no gutunganya aside amine ituma iba igikoresho gikomeye cyo kunoza ubuzima bw'abantu. Bitewe n'uko ubushakashatsi bwa siyansi bukomeje kwiyongera, bikekwa ko ikoreshwa rya kalisiyumu α-ketoglutarate mu rwego rw'ibicuruzwa by'ubuvuzi bizitabwaho cyane kandi bigatera imbere.
