Protein (mai gina jiki)

Protein sune muhimman abubuwan gina jiki ga Jikin mutum. Suna ɗaya daga cikin ƙwayoyin jiki kuma suna aiki a matsayin Tushen mai fetur. A matsayin man fetur, sunadarai suna da irin wannan ƙarfin makamashi kamar carbohydrates: 17 kJ (4 kcal) a kowace gram. Halin da ke bayyana furotin daga ra'ayi mai gina jiki shine abun da ke cikin Amino acid.  

Protein sune sarƙoƙi na polymer da aka yi da amino acid da aka haɗa da haɗin peptide. A lokacin narkewar ɗan adam, sunadarai suna raguwa a ciki ciki zuwa ƙananan sarƙoƙi na polypeptide ta hanyar ayyukan hydrochloric acid da protease. Wannan yana da mahimmanci ga shawo kan mahimman amino acid waɗanda jiki ba zai iya haɗawa da su ba.
