Ingaruka za mannose ku isukari mu maraso ni nto cyane, ndetse dushobora no kuvuga ko "nta ngaruka zigira" ku rugero rw'isukari mu maraso. Iri ni itandukaniro ryibanze hagati yacyo nandi masukari menshi nka glucose.

Dore ibisobanuro birambuye:

Inzira zitandukanye zo guhinduranya:

Glucose: Nisoko nyamukuru yingufu zumubiri. Yinjizwa neza n amara (hafi 100%), yinjira mumaraso (izamura isukari yamaraso), hanyuma ifatwa, ikoreshwa, cyangwa ibikwa ningirabuzimafatizo hifashishijwe insuline (nka glycogene, ibinure).

Mannose: Nubwo nayo ari monosaccharide (isukari itandatu ya karubone), inzira ya metabolike mu mubiri itandukanye rwose na glucose.

Igipimo gito cyo kwinjiza: Uburyo bwo kwinjiza amara bwa mannose buri hasi cyane ugereranije na glucose (hafi 20% cyangwa munsi).

Ntabwo biterwa na insuline: Nyuma yo kwinjizwa mu mwijima, mannose hafi ya yose iba fosifori muri mannose-6-fosifate na enzymes zihariye (cyane cyane mannose kinase).

Guhindura Fructose-6-fosifate: Mannose-6-fosifate ihindurwamo Fructose-6-fosifate na fosifomannose isomerase.

Kwinjira munzira ya glycolysis: Fructose-6-fosifate nigicuruzwa giciriritse munzira ya glycolysis ishobora kurushaho guhindurwa kugirango itange ingufu. Urufunguzo ni uko iyi nzira yo guhindura irenga intambwe zingenzi nka glucokinase na glucose-6-fosifate, kandi ntibishingiye kubikorwa bya insuline. ?

Kudatera insuline gusohora:

?

Bitewe nuko mannose ubwayo atariyo nyamukuru itera isukari yo mu maraso hejuru (hamwe n'amafaranga make yinjira mu maraso n'inzira zitandukanye za metabolike), ntabwo itera cyane ingirabuzimafatizo za beta zo mu bwoko bwa beta gusohora insuline nka glucose. Ubushakashatsi bwerekanye ko gukoresha umunwa mannose bitongera cyane glucose yamaraso na insuline.

Ibimenyetso byubuvuzi nubushakashatsi:

?

Umubare muto wubushakashatsi bwakorewe ku bantu bafite ubuzima bwiza n’abarwayi ba diyabete yo mu bwoko bwa 2 bwerekanye ko no ku kigero cyo hejuru cyane (nk'uburemere bwa 0.2 g / kg ibiro, bingana na 14 g ku muntu 70 kg), mannose yo mu kanwa ntabwo yateje ihindagurika rikomeye mu maraso ya glucose.

Ubushakashatsi bw’inyamaswa nabwo bwagiye bwerekana ko mannose itongera urugero rwisukari mu maraso.

Vuga muri make impamvu zituma mannose igira ingaruka nke ku isukari mu maraso:

?

Igipimo gito cyo kwinjiza: Hafi ya mannose yinjiye ntabwo yinjizwa kandi ikoreshwa neza cyangwa isohoka na bagiteri zo munda.

Inzira idasanzwe yo guhinduranya: Igice cyinjijwe gihinduka vuba muri fructose-6-fosifate mu mwijima binyuze mu nzira yigenga ya insuline kandi ikinjira muri glycolysis, ikirinda gutembera neza nka glucose yamaraso (glucose).

Insuline idatera imbaraga: Kubura imbaraga zo gukurura isukari mu maraso, ntabwo rero itera gusohora kwa insuline.

Amatangazo y'ingenzi:

?

Igipimo: Imyanzuro yavuzwe haruguru ishingiye cyane cyane kumyanya isanzwe yinyongera (ubusanzwe ikoreshwa mubikorwa byubuzima bwinkari, hafi garama 1-2 kumunsi) hamwe nubushakashatsi bumwe na bumwe (nka 0.2g / kg). Mubyigisho, dosiye ndende cyane irashobora kubyara imitwaro itandukanye, ariko mubisanzwe ntabwo ikoreshwa kubwiyi ntego.

Kuryoshya: Uburyohe bwa mannose bugera kuri 70% bya sucrose, ariko rimwe na rimwe buvugwa nkibishobora kuba "indangagaciro ya glycemic index sweetener" kubera ko itagira ingaruka ku isukari mu maraso kandi ikinjira cyane. Ariko igiciro cyacyo nuburyohe (birakaze gato) nkibiryoheye bigabanya gukoreshwa kwinshi.

Ikoreshwa ryingenzi: Kugeza ubu, uburyo nyamukuru bwo gukoresha mannose bushingiye ku bushobozi bwabwo bwo kubangamira ifatira rya bagiteri (cyane cyane Escherichia coli) ingirabuzimafatizo zo mu nkari epithelial selile, mu rwego rwo gukumira no kuvura indwara zanduza inkari (UTIs). Ibiranga isukari mu maraso biranga guhitamo neza kubarwayi ba diyabete cyangwa abantu bafite isukari mu maraso mugihe bakeneye kwirinda kwandura inkari (birumvikana ko bagikurikiza inama za muganga).

Itandukaniro ryabantu kugiti cyabo no kugisha inama abaganga: Nubwo uburyo bwa metabolike bwerekana ko butagira ingaruka ku isukari yamaraso, hashobora kubaho itandukaniro hagati yabantu. Niba ufite diyabete ikomeye cyangwa izindi ndwara ziterwa na metabolike, nibyiza kubaza muganga mbere yo gukoresha mannose nk'inyongera.

Umwanzuro:

Mannose ni isukari idasanzwe, kubera umuvuduko muke wo mu mara hamwe ninzira idasanzwe, insuline yigenga ya metabolike yigenga mu mwijima, ntibishobora gutuma kwiyongera k'urwego rw'isukari mu maraso kandi bidatera gusohora insuline. Ibi bituma umutekano muke kubantu bakeneye kugenzura isukari yamaraso (nkabarwayi ba diyabete) kuruta ayandi masukari, cyane cyane iyo akoreshwa mukurinda kwandura inkari.
