I-Alanine (ekwabizwa ngokuba yi-2-aminopropanoic acid, i-aminopropanoic acid) i-amino acid enceda umzimba ukuguqula i-glucose elula ibe amandla kunye nokuphelisa i-toxins engaphezulu kwesibindi.Ii-amino acids ziibhloko zokwakha zeeprotheyini ezibalulekileyo kwaye zingundoqo ekwakheni izihlunu ezomeleleyo nezisempilweni.I-Alanine yeye-amino acids ezingabalulekanga, ezinokuthi zenziwe ngumzimba.Nangona kunjalo, zonke ii-amino acids zinokuba yimfuneko ukuba umzimba awukwazi ukuzivelisa.Abantu abanokutya okuneprotheyini ephantsi okanye ukuphazamiseka kokutya, isifo sesibindi, isifo sikashukela, okanye iimeko zofuzo ezibangela i-Urea Cycle Disorders (UCDs) kunokufuneka ukuba bathathe izongezo ze-alanine ukuphepha ukusilela.
