I-L-Selenomethionine: Isizukulwana Esitsha Esingumthombo We-Organic Selenium Kwisondlo Sezilwanyana

Kwifama yemfuyo yanamhlanje, iindlela zokutya ziya ziphucuka ngakumbi, kwaye ukongeza izinto ezincinci akunto intsha. Kodwa xa kufikwa kwi-selenium, usenokuba ukhe weva nge-sodium selenite okanye i-selenium yeast, kodwa usenokungaqhelananga ne-compound efumana ingqalelo ekhulayo kubavelisi bokutya: i-L-selenomethionine.

Ngamafutshane, i-L-selenomethionine ngumthombo we-selenium yendalo–i-selenoamino acid yendalo efumaneka kwizityalo nakwiinkozo zokutya, apho i-selenium ibotshelelwe kwimo yendalo. Xa ithelekiswa ne-selenium yendabuko engaphiliyo (njenge-sodium selenite), i-L-selenomethionine inika iingenelo ezintathu eziphambili: ubuthi obuphantsi, ungcoliseko oluncinci lokusingqongileyo, kunye nokufumaneka okuphezulu kakhulu kwezinto eziphilayo. Ngenxa yezi ngenelo, imithetho kwihlabathi liphela iye yanciphisa kancinci imiqathango ekusebenziseni i-L-selenomethionine ekutyeni, nto leyo eyenza ukuba ibe lukhetho olutsha oluthembisayo kwisondlo sezilwanyana.

Ngoko ke yintoni eyenza i-L-selenomethionine ibonakale? Liliphi ixabiso lokwenyani elinokuyizisa kwimveliso yemfuyo? Masithi'jonga ngokusondeleyo.

1. YintoniI-L-Selenomethionine?

Ukuba awuqhelananga ne-biochemistry, apha'isifaniso esilula: I-Methionine yi-amino acid ebalulekileyo kwizilwanyana. I-L-selenomethionine yenziwa ngokutshintsha i-athomu yesalfure kwi-methionine nge-athomu yeselenium. Olu tshintsho lubonakala lulula luyinika iipropati ezikhethekileyo.

Kwindalo, i-selenium ikhona ikakhulu ngeendlela ezimbini.–i-inorganic kunye ne-organic. I-inorganic selenium iquka i-sodium selenite kunye ne-selenate, ngelixa i-organic selenium ibhekisa ikakhulu kwi-selenoamino acids ezifana ne-selenomethionine kunye ne-selenocystine. I-L-selenomethionine lolona hlobo luphambili lwe-organic selenium olufumaneka kwi-selenium yeast, kwaye ikwangumthombo we-organic selenium ophambili kwizityalo nakwiinkozo.

I-L-selenomethionine inamandla akhethekileyo: inokufunxwa ngqo zizilwanyana kwaye ifakwe kwiiproteni ezakhiweyo zemisipha, isibindi, kunye nezinye izicubu, zenze ichibi lokugcina i-selenium emzimbeni. Ngokwahlukileyo koko, ezinye iintlobo ze-selenium (kuquka i-selenium engaphiliyo kunye nezinye izinto eziphilayo ze-selenium) ekugqibeleni ziyancitshiswa zibe yi-hydrogen selenide, kwaye nayiphi na into egqithisileyo ikhutshwa kwaye ayinakugcinwa. Izifundo zibonise ukuba xa iinkukhu zinikwa i-sodium selenite, izinga lokukhupha i-selenium liphezulu ngokuphindwe kathathu kunaxa zinikwa i-L-selenomethionine.–eqinisekisa ukuba i-selenium engaphiliyo kunzima ukuyigcina emzimbeni wesilwanyana.

Yiyo kanye le nto“igcinwe"uphawu olwenza i-L-selenomethionine ibonakale phakathi kwemithombo ye-selenium.
