Kev siv

Arbutin muaj cov txiaj ntsig ntawm kev ua kom tawv nqaij. Nws tuaj yeem nkag mus rau hauv daim tawv nqaij tsis muaj kev cuam tshuam cov tawv nqaij tawv nqaij. Nws tuaj yeem sib txuas nrog tyrosine uas ua rau melanin ntau lawm ntawm tyrosine thiab tsim ntawm melanin, thiab ua kom muaj kev cuam tshuam ntawm melanin. Tsis tas li ntawd, Arbutin tseem tuaj yeem tiv thaiv cov tawv nqaij los ntawm dawb radicals thiab muaj zoo hydrophilicity
