EBINTU BYONNNA N’AMAWULIRE GW’EBINTU EBIweereddwa KU MUTINDO GUNO BIKOZESEBWA KU KUSASANYA AMAWULIRE N’EBIKOLWA BY’OKUSOMESA.
Ebintu ebiweereddwa ku mukutu guno bigendereddwamu kunoonyereza mu kisenge (in vitro research) byokka. Okunoonyereza mu vitro (Olulattini: *mu ndabirwamu*, ekitegeeza mu bikozesebwa mu ndabirwamu) kukolebwa ebweru w’omubiri gw’omuntu. Ebintu bino si bya ddagala, tebikkiriziddwa kitongole kya Amerika ekivunaanyizibwa ku by’emmere n’eddagala (FDA), era tebirina kukozesebwa kuziyiza, kujjanjaba oba kuwonya mbeera yonna ya bujjanjabi, bulwadde oba bulwadde. Kikugirwa nnyo mu mateeka okuyingiza ebintu bino mu mubiri gw’omuntu oba ebisolo mu ngeri yonna.
Okulambika okutwaliza awamu
Glutathione, era amanyiddwa nga glutathione, kirungo kikulu ekisangibwa ennyo mu biramu. Ye tripeptide ekolebwa asidi wa glutamic, cysteine ne glycine. Kiyinza okusangibwa mu butoffaali bw’ebisolo ebiyonka, ebimera, n’obuwuka obutonotono obungi, nga kino kikola omulimu ogw’ekitalo mu butoffaali. Glutathione amanyiddwa nga 'Master Antioxidant' olw'amaanyi gaayo agaziyiza obuwuka obuleeta obulwadde. Omutwe guno guva ku bungi bwagwo mu butoffaali n’obusobozi bwagwo okukolagana n’ebirungo ebirala ebiziyiza obuwuka obuleeta obulwadde okutumbula ebikolwa byabwe eby’okuziyiza obuwuka obuleeta obulwadde.
Ekifaananyi 1 Ekikolwa ekikwatagana eky’enziyiza eziziyiza obuwuka obuleeta obulwadde bwa superoxide dismutase, catalase, ne glutathione peroxidase.
Emirimu
Okugogola free radicals n’okukuuma obutoffaali ne mitochondria: Free radicals molekyu ezikola ennyo ezikolebwa mu kiseera ky’okukyusakyusa obutoffaali. Free radicals ezisukkiridde zisobola okuleeta okwonooneka kwa oxidative ne peroxidative ku butoffaali ne mitochondria. Glutathione akolagana ne free radicals okuyita mu kibinja kyayo ekya sulfhydryl (-SH), n’ezifuula ebintu ebinywevu ennyo, bwe kityo n’eziyiza free radicals okulumba obutoffaali ne mitochondria n’okukuuma ensengekera n’enkola ya bulijjo ey’obutoffaali. Obutoffaali bwe bukwatibwa ebizibu eby’ebweru nga emisinde gya ultraviolet oba emisinde, omuwendo omunene ogwa free radicals zikolebwa. Glutathione asobola okuddamu amangu okumalawo ebirungo bino ebiyitibwa free radicals, ekikendeeza ku bulabe bw’okwonooneka kw’obutoffaali.
Okwetaba mu bbalansi y’enkyukakyuka y’emmere: Mu bakitiriya, glutathione yeetaba mu nkola za redox mu kiseera ky’enkyukakyuka y’emmere. Okuyita mu nkola ya enzymatic reactions, ekuuma balance munda mu mubiri. Enzikiriziganya eno esobozesa bakitiriya okuziyiza butereevu oba obutatereevu enkyukakyuka ez’enjawulo ezireetebwa ensonga z’obutonde n’enkyukakyuka yazo mu mubiri nga zikula, gamba ng’omukka gwa okisigyeni omungi, puleesa y’omukka ey’amaanyi, eddagala, ne ayoni z’ebyuma. Bakitiriya bwe ziba mu mbeera erimu okisigyeni omungi, zikola ebika bya okisigyeni ebikola (ROS) bingi. Glutathione asobola okukendeeza ku ROS okuyita mu nkola eziddiriŋŋana, okusobozesa obuwuka okuwangaala mu mbeera ng’ezo.
Okuggya obutwa mu mubiri: Glutathione asobola okwesiba n’obutwa, ebyuma ebizito, n’ebintu ebirala eby’obulabe mu butoffaali, n’abifuula ebintu ebitali bya butwa oba ebirimu obutwa obutono n’okutumbula okubifulumya mu mubiri. Wansi w’okunyigirizibwa kw’ebyuma ebizito, emiwendo gya glutathione mu butoffaali bw’ebimera gyeyongera. Kikola ebizibu n’ebyuma ebizito, ne kikendeeza ku butwa bwabyo eri obutoffaali bw’ebimera. Glutathione era esobola okwesiba n’ebintu eby’obutwa ebisikiriza amasannyalaze okuziyiza okwonooneka kw’ebiramu ebikulu mu butoffaali (nga puloteyina ne nucleic acids), bwe kityo n’ekuuma obutoffaali okuva ku butwa.
Okwongera ku busimu obuziyiza endwadde: Glutathione naye akola kinene nnyo mu baserikale b’omubiri. Kisobola okulung’amya enkola y’obutoffaali bw’abaserikale b’omubiri, okutumbula emirimu gyabwo, era bwe kityo ne kirongoosa enkola y’abaserikale b’omubiri. Kiyinza okukwata ku kweyongera n’okwawukana kwa T lymphocytes ne B lymphocytes, okusobozesa abaserikale b’omubiri okutegeera obulungi n’okumalawo obuwuka obuleeta endwadde obugwira, n’okuyamba omubiri okuziyiza yinfekisoni n’endwadde.
Okusaba
Okukuuma ekibumba: Ekibumba kitundu kikulu ekiggya obutwa mu mubiri gw’omuntu era kiyinza okwonooneka olw’ebintu eby’obulabe eby’enjawulo mu nkola y’okukyusakyusa emmere. Glutathione ayongera ku nkola y’ekibumba ey’okuggya obutwa mu kibumba n’okutumbula okuddaabiriza n’okuddamu okukola obutoffaali bw’ekibumba. Mu bujjanjabi, etera okukozesebwa okujjanjaba endwadde ez’enjawulo ez’ekibumba ez’amaanyi n’ez’olubeerera, gamba ng’obulwadde bw’ekibumba obuva ku mwenge n’obuvune bw’ekibumba obuva ku ddagala. Ku kwonooneka kw’ekibumba okuva ku mwenge okuva ku kunywa omwenge okumala ebbanga eddene, glutathione esobola okukendeeza ku kwonooneka kw’ekibumba okuva ku oxidative stress ng’eyoola free radicals, bwe kityo n’alongoosa ebiraga enkola y’ekibumba.
Obujjanjabi bw’obuzibu bw’endwadde z’omu lubuto: Enkola eya bulijjo ey’enkola y’endwadde z’omu lubuto kikulu nnyo mu kukuuma bbalansi y’omubiri mu mubiri gw’omuntu. Glutathione asobola okulungamya okusengejja, okufulumya, n’okukyusakyusa obusimu mu nkola y’endwadde z’omu lubuto, bwe kityo n’akola ekikolwa eky’obujjanjabi ku ndwadde ezikwatagana n’obuzibu bw’endwadde z’omubiri. Okugeza, mu ndwadde ezimu eza thyroid, glutathione eyinza okutereeza embeera ya redox mu butoffaali bwa thyroid, bwe kityo n’ekwata ku kusengejja n’okufulumya obusimu bwa thyroid n’okulongoosa embeera.
Obujjanjabi obuyamba ku bizimba: Obutoffaali bw’ekizimba bukola ebirungo bingi ebiyitibwa free radicals nga bikula n’okukula. Okugatta ku ekyo, eddagala eriweweeza ku bulwadde n’eddagala eriyitibwa radiation therapy erikozesebwa mu kujjanjaba ebizimba nabyo bisobola okwongera ku situleesi ya oxidative mu mubiri. Glutathione asobola okukozesebwa ng’eddagala ery’okuyambako okukendeeza ku kwonooneka okuva mu ddagala n’obujjanjabi obw’amasannyalaze ku butoffaali obwa bulijjo, bwe kityo n’alongoosa omutindo gw’obulamu bw’abalwadde. Kiyinza okuyoola obuwuka obuyitibwa free radicals, okukendeeza ku kwonooneka kw’okunyigirizibwa okw’okwokya (oxidative stress damage) ku bitundu ebya bulijjo, n’okutumbula okuwuliziganya kw’obutoffaali bw’ekizimba eri eddagala ly’eddagala nga kitereeza amakubo g’obubonero mu butoffaali, bwe kityo ne kirongoosa obulungi bw’obujjanjabi.
Okwerusa olususu n’okulabirira: Glutathione asobola okuziyiza emirimu gya tyrosinase, okukendeeza ku kukola melanin, n’okutuuka ku bikolwa ebyerusa olususu. Obulung’amu bwayo obuziyiza obuwuka obuleeta obulwadde buno busobola okumalawo obuwuka obuyitibwa free radicals mu butoffaali bw’olususu, okulwawo okukaddiwa kw’olususu, n’okukendeeza ku kulabika kw’enviiri n’amabala ag’emyaka. Ebizigo bingi ebyerusa olususu n’okuziyiza okukaddiwa birimu ebirungo bya glutathione.
Okuddaabiriza Olususu Oluyonooneddwa: Olususu olukwatibwa emisinde gya UV, obucaafu bw’obutonde, n’ebintu ebirala biyinza okwonooneka. Glutathione atumbula okuddaabiriza n’okuzza obuggya obutoffaali bw’olususu obwonooneddwa, anyweza enkola y’olususu oluziyiza, n’okulongoosa obulamu bw’olususu okutwalira awamu. Ku lususu oluyokeddwa omusana oba olulina alergy, ebikozesebwa mu kulabirira olususu ebirimu glutathione bisobola okuyamba okukendeeza ku bubonero n’okwanguyiza olususu okudda engulu.
Mu bufunzi
Mu bufunze, glutathione, n’obusobozi bwayo obw’amaanyi obw’okuziyiza obuwuka obuleeta obulwadde n’emirimu emikulu mingi mu mubiri, ekola kinene mu bintu eby’enjawulo omuli n’eddagala.
