I-Lectins lusapho lweeproteni ezifumaneka phantse kuko konke ukutya, ngakumbi iimbotyi kunye neenkozo.

Abanye abantu babanga ukuba i-lectins ibangela ukonyuka kwamathumbu kwaye iqhube izifo ezenzekelayo.

Ngelixa kuyinyani ukuba ii-lectins ezithile zinetyhefu kwaye zibangela ukwenzakala xa zisetyenziswa kakhulu, kulula ukuzisusa ngokupheka.

Kananjalo, unokuzibuza ukuba ii-lectins zibeka umngcipheko empilweni.

Eli nqaku likuxelela yonke into ekufuneka uyazi malunga nectins.

Yintoni ii-lectins?

I-Lectins lusapho olwahlukeneyo lweeproteni ezibopha i-carbohydrate ezifumaneka kuzo zonke izityalo nakwizilwanyana ().

Ngelixa izilwanyana ze-lectins zidlala iindima ezahlukeneyo kwimisebenzi eqhelekileyo yomzimba, indima ye-lectins yezityalo ayicacanga. Nangona kunjalo, zibonakala ngathi ziyabandakanyeka kukhuseleko lwezityalo ngokuchasene nezinambuzane kunye nezinye izilwanyana ezitya utyani.

Ezinye ii-lectins zezityalo zinetyhefu. Kwimeko yetyhefu enetyhefu- i-lectin evela kwisityalo seoyile ye-castor-inokubulala.

Nangona phantse konke ukutya kugcina i-lectins, kuphela kuqikelelwa i-30% yokutya okuqhelekileyo okutyiwa e-United States kunexabiso elibalulekileyo ().

Iimbotyi, kubandakanya iimbotyi, iimbotyi zesoya, kunye namandongomane, zibamba ii-lectins zezityalo, zilandelwe ziinkozo kunye nezityalo kusapho lwase-nightshade.

I-Lectins lusapho lweeproteni ezibopha i-carbohydrate. Zenzeka phantse kuko konke ukutya, kodwa awona manani aphezulu afumaneka kwimidumba nakwiinkozo.

Ezinye ii-lectins zinokuba yingozi

Njengezinye izilwanyana, abantu baneengxaki zokwetyisa i-lectins.

Ngapha koko, ii-lectins zichasene kakhulu nee-enzymes zomzimba wakho zokugaya kwaye zinokudlula ngokulula kwisisu sakho ezingatshintshanga ().

Ngelixa ii-lectins kukutya kwezityalo ezityiwayo zihlala ingeyiyo inkxalabo yezempilo, kukho ezimbalwa okwahlukileyo kuzo.

Umzekelo, iimbotyi zezintso ekrwada ziqulathe i-phytohaemagglutinin, i-lectin enetyhefu. Ezona mpawu ziphambili zetyhefu yeembotyi zezintso ziintlungu zesisu, ukugabha kunye norhudo ().

Iziganeko ezichaziweyo zobu tyhefu zinxulunyaniswa neembotyi ezibomvu zezintso eziphekiweyo. Iimbotyi zezintso eziphekwe ngokufanelekileyo zikhuselekile ukuba zingatya.

Iilectins ezithile zinokubangela uxinzelelo lokugaya ukutya. IPhytohaemagglutinin, efumaneka kwimbotyi yezintso ekrwada, inokuba yityhefu.

Ukupheka kuthoba uninzi lweelectins kukutya

Abaxhasi bokutya kwe-paleo bathi ii-lectins ziyingozi, besithi abantu mabasuse iimbotyi kunye neenkozo ekudleni kwabo.

Nangona kunjalo, ii-lectins zinokupheliswa ngokupheka.

Ngapha koko, ukubilisa iimbotyi emanzini kususa phantse yonke imisebenzi ye-lectin (,).

Ngelixa iimbotyi ebomvu ebomvu yezintso iqulethe iiyunithi ezingama-20,000-70,000 ze-hemagglutinating (HAU), eziphekiweyo zine-200-400 HAU kuphela - ithontsi elikhulu.

Kwisifundo esinye, ii-lectins kwiimbotyi zesoya zazisuswa ikakhulu xa iimbotyi zazibiliswa imizuzu emi-5-10 kuphela (7).

Kananjalo, awufanele ukuthintele iimbotyi ngenxa yemisebenzi ye-lectin kwimidumba eluhlaza - njengoko oku kutya kuhlala kuphekiwe kuqala.

Ukupheka kumaqondo obushushu aphezulu kususa ngokufanelekileyo umsebenzi we-lectin kukutya okufana nembotyi, kubenza ukuba bakhuseleke ngokugqibeleleyo ukuba bangatya.

Umgca wezantsi

Nangona ezinye i-lectins zokutya zinetyhefu kwiidosi ezinkulu, abantu ngokubanzi abayityi loo nto.

Ukutya okunotye i-lectin okutyiwa ngabantu, okufana neenkozo kunye neembotyi, kuhlala kuhlala kuphekwe ngenye indlela kwangaphambili.

Oku kushiya kuphela isixa esincinci se-lectins sokusetyenziswa.

Nangona kunjalo, izixa ekutyeni ziphantsi kakhulu ukuba zingasongela abanye abantu abasempilweni.

Uninzi lwezi zinto ziqulathe lectin ziphezulu kwiivithamini, iiminerali, ifayibha, ii-antioxidants, kunye nezinto ezininzi eziluncedo.

Izibonelelo zezi zondlo zisempilweni zigqithile kwiziphumo ezibi zokulandela umkhondo wexabiso lectins.
