Ma muli o ka hoʻoheheʻe ʻana o nā antioxidants, hiki ke hoʻokaʻawale ʻia i ʻelua ʻāpana: wai-soluble antioxidants a me ka momona-soluble antioxidants. Loaʻa nā antioxidants hiki ke hoʻoheheʻe ʻia i ka wai i loko o ka cytoplasmic matrix a me ka plasma, aʻo ka momona -soluble antioxidants e pale i nā lipid o nā membrane cell mai ka peroxidation. Ua biosynthesized kēia mau pūhui i loko o ke kino o ke kanaka a i ʻole ʻia ma o ka ʻai ʻana. Hoʻokaʻawale ʻia nā antioxidants like ʻole i loko o nā wai kino a me nā ʻiʻo i kekahi ʻano o nā ʻano. Loaʻa ka Glutathione a me ka coenzyme Q10 i loko o nā pūnaewele, aʻo nā antioxidants ʻē aʻe e like me ka uric acid e laha nui ʻia (e nānā i ka papa ma lalo no nā kikoʻī). Aia kekahi mau antioxidants i loko o kekahi mau kiko kino kiko'ī ma muli o ko lākou mau hopena antioxidant a me nā pathogens koʻikoʻi a me nā kumu pathogenic.
Hoʻohui a chelate kekahi mau pūhui me nā metala hoʻololi e pale i ka metala mai ka hoʻoulu ʻana i ka hana ʻana o nā radical manuahi i loko o nā cell, no laila ke pāʻani nei i ka pale antioxidant. ʻO kahi mea koʻikoʻi ma kēia ʻano pale -oxidant, ʻo ia ka hoʻokaʻawale ʻana i nā ion hao ma o ka hoʻohui ʻana i ka chelation, no ka mea, ʻo nā ion hao ke kī o kekahi mau protein paʻa hao e like me transferrin a me ferritin . . Selenium a me zinc i manaʻo ʻia he mau meaʻai antioxidant. ʻAʻohe hopena antioxidant o kēia mau mea ʻelua akā hiki ke pāʻani i ka hana o kekahi mau enzyme antioxidant.
