Ososayensi bathole ukuthi i-3-O-ethyl ascorbic acid, eyaziwa nangokuthi i-EAA, iwumkhiqizo wemvelo onezakhiwo zokulwa ne-antioxidant kanye nokulwa nokuvuvukala, ingase ibe nokusetshenziswa okungenzeka kwezokwelapha kanye nezithasiselo zezempilo.
Ucwaningo olwenziwe eNyuvesi yaseCalifornia, eLos Angeles (UCLA) luthole ukuthi i-3-O-ethyl ascorbic acid, idlala indima ebalulekile ekuvikeleni amangqamuzana ekucindezelekeni kwe-oxidative kanye nokuvuvukala. Ngokungafani ne-vitamin C evamile, emuncwa ngokushesha emzimbeni bese isuswa, i-EAA imuncwa kancane kancane futhi ihlala emzimbeni isikhathi eside, ihlinzeka ngokuvikelwa okuqhubekayo kuma-free radicals kanye nokuvuvukala.
Lolu cwaningo, olushicilelwe ephephabhukwini i-Nature, lusikisela ukuthi i-EAA ingathuthukiswa ibe yindlela yokwelapha engaba khona yezifo ezahlukahlukene ezibonakala ngokucindezeleka kwe-oxidative kanye nokuvuvukala, njengomdlavuza, izifo zenhliziyo, kanye nezinkinga ze-neurodegenerative. Ngaphezu kwalokho, i-EAA ingase futhi ibe nezicelo embonini yezimonyo njengesithako sokulwa nokuguga ngenxa yamandla ayo okuvikela ekucindezelekeni kwe-oxidative kanye nokuvuvukala.
Ekuthuthukisweni okusha, abacwaningi bathole ukuthi i-3-O-ethyl ascorbic acid ether, eyaziwa nangokuthi i-vitamin C ethyl ether, inganikeza ikhambi lokulinganiselwa kwe-vitamin C yendabuko ekusetshenzisweni kwezimonyo. Ngenxa yokuba khona kwamaqembu amane e-hydroxyl esakhiweni sayo, i-vitamin C ngokwayo ayikwazi ukumuncwa ngqo yisikhumba futhi ithambekele ekungcolisweni, okubangela ukushintsha kombala. Lokhu kunciphise ukusetshenziswa kwayo njenge-ejenti yokwenza mhlophe ezimonyo. Ngaphezu kwalokho, ososayensi bathole ukuthi i-vitamin C ethyl ether, etholakala ngokuxuba iqembu le-hydroxyl elinezikhundla ezintathu, iyi-derivative engashintshi umbala ye-vitamin C egcina umsebenzi wayo webhayoloji. Lokhu kutholakala kugcwalisa isikhala emakethe yemikhiqizo efanayo. Imiphumela ekhuthazayo evela ocwaningweni ikhombisa ukuthi i-vitamin C ethyl ether ihlakazeka kalula ngama-enzyme lapho ingena esikhumbeni, okuvumela ukuthi ifeze indima efanayo ne-vitamin C ekukhuthazeni impilo yesikhumba kanye nokwenza mhlophe.
I-Uniproma ibilokhu ihlinzeka ngekhwalithi ephezuluI-PromaCare EAAKuye kwathengiswa emakethe yomhlaba wonke iminyaka eminingi futhi umkhiqizo waziwa kakhulu emakethe ngokusebenza kahle kanye nokuzinza okuhle.
