Ucwaningo lwakamuva olushicilelwe ku-Journal of Nutrition lukhanyisele izinzuzo ezingaba khonai-leucine, i-amino acid ebalulekile, empilweni yemisipha. Lolu cwaningo olwenziwe ithimba labacwaningi abavela emanyuvesi aphambili, kuhloswe ngalo ukuphenya ngemiphumelai-leucineukwesekwa ku-muscle protein synthesis kanye nempilo yemisipha jikelele. Okutholwe kulolu cwaningo kunemiphumela ebalulekile kubasubathi, abantu abadala, kanye nabantu abafuna ukuthuthukisa impilo yabo yemisipha.
I-LeucineUmthelela Wezempilo Nokuphila Udaluliwe:
Ucwaningo lwalubandakanya indlela eqinile ngokwesayensi, lapho kwanikezwa ababambiqhazai-leucineizithasiselo kanye nokwakheka kwamaprotheni emisipha kuqashwe ngokucophelela. Imiphumela iveze lokhoi-leucineukwesekwa kwandise kakhulu ukuhlanganiswa kwamaprotheni emisipha, okubonisa indima yayo engaba khona ekukhuthazeni ukukhula nokulungisa imisipha. Lokhu okutholakele kubaluleke kakhulu kubasubathi nakubantu abafuna ukuthuthukisa imisipha namandla abo.
Ngaphezu kwalokho, ucwaningo luphinde lwagqamisa izinzuzo ezingaba khonai-leucinekubantu abadala. Njengoba abantu bekhula, ukugcinwa kwemisipha namandla kuya ngokuya kubaluleke kakhulu empilweni nasekunyakazeni jikelele. Abacwaningi bathola lokhoi-leucineukwesekwa kungasiza abantu abadala asebekhulile balondoloze isisindo semisipha nokusebenza, okungase kunciphise ingozi yokulahlekelwa kwemisipha ehlobene nobudala kanye nobuthakathaka.
Umphakathi wesayensi ukwamukele lokhu okutholakele, ugcizelela ukubaluleka koku i-leucineekukhuthazeni impilo yemisipha. UDkt. Sarah Johnson, uchwepheshe wezokudla ohamba phambili, waphawula, “Lolu cwaningo luhlinzeka ngemininingwane ebalulekile mayelana nezinzuzo ezingaba khonai-leucineimpilo yemisipha. Okutholakele kusekela umbono wokuthii-leucineukwesekwa kungaba yisu elibalulekile kubantu abafuna ukuthuthukisa impilo yabo yemisipha, kungakhathaliseki ukuthi bangabasubathi noma abantu abadala. "
Sengiphetha, okutholwe yilolu cwaningo kugqamise izinzuzo ezingaba khona zei-leucineukwengezwa kwempilo yemisipha. Ngamandla ayo okuthuthukisa ukwakheka kwamaprotheni emisipha futhi igcine izicubu zemisipha kubantu abadala asebekhulile,i-leucinekunesithembiso njengesithako esibalulekile sokudla okunempilo sokuthuthukisa impilo yemisipha. Njengoba ucwaningo olwengeziwe lusaqhubeka ukuhlola indima yei-leucineempilweni yemisipha, lokhu okutholakele kunikeza imininingwane ebalulekile kubantu abafuna ukuthuthukisa ukusebenza kwabo ngokomzimba kanye nempilo enhle iyonke.
