Raws li kev solubility ntawm antioxidants, nws tuaj yeem muab faib ua ob pawg: dej-soluble antioxidants thiab fat-soluble antioxidants. Cov dej-soluble antioxidants feem ntau pom muaj nyob rau hauv cytoplasmic matrix thiab plasma, thaum muaj roj-soluble antioxidants tiv thaiv lipids ntawm cell membranes los ntawm peroxidation. Cov tebchaw no yog biosynthesized hauv tib neeg lub cev lossis noj los ntawm kev noj zaub mov. Cov tshuaj antioxidants sib txawv tau muab faib rau hauv cov kua hauv lub cev thiab cov ntaub so ntswg hauv qee qhov ntau ntawm cov concentrations. Glutathione thiab coenzyme Q10 feem ntau pom muaj nyob hauv cov hlwb, thaum lwm cov tshuaj tiv thaiv antioxidants xws li uric acid tau muab faib ntau dua (saib cov lus hauv qab no kom paub meej). Qee cov tshuaj antioxidants tsuas yog muaj nyob hauv qee cov ntaub so ntswg ntawm lub cev vim tias lawv cov teebmeem antioxidant thiab tseem muaj cov kab mob tseem ceeb thiab cov kab mob pathogenic.
Qee cov tebchaw sib koom ua ke thiab chelate nrog kev hloov pauv hlau los tiv thaiv cov hlau los ntawm kev tsim cov dawb radicals hauv hlwb, yog li ua lub luag haujlwm hauv kev tiv thaiv antioxidant. Ib qho tseem ceeb tshwj xeeb hauv txoj kev tiv thaiv oxidant no yog cais cov hlau ions los ntawm kev sib koom tes chelation, vim hais tias hlau ions yog tus yuam sij rau qee cov hlau-binding proteins xws li transferrin thiab ferritin. . Selenium thiab zinc feem ntau suav tias yog cov khoom noj antioxidant. Ob lub ntsiab lus no tsis muaj cov nyhuv antioxidant tab sis tuaj yeem ua lub luag haujlwm hauv kev ua haujlwm ntawm qee cov enzymes antioxidant.
