Kunoma ikuphi, lawa ma-radicals wamahhala angama- izinto ayizinzile, Iyakwazi ukusabela namanye ama-molecule futhi idale izinkinga ngaphakathi kwamaseli. Sikhuluma nge-oxidation.

Ama-radicals amahhala, uma emaningi kakhulu, ahlasela amaseli, amaprotheni aqukethe, i- I-ADN, njengomphumela oyinhloko ukuguga okusheshisiwe. Lokhu kuhunyushwa ngokubukeka okukhulu kwe- imibimbi, ingozi eyengeziwe yesifo senhliziyo, umdlavuza.
Este ukungalingani phakathi kokukhiqizwa kwama-radicals amahhala nokuvikelwa komzimba kungachazwa yizinto eziningi. I- antioxidants bakha ukusabela komzimba ekuhlaselweni kwama-radicals wamahhala. Umphumela wabo ukuwanciphisa uma kwenzeka ngokweqile futhi kunciphise umonakalo wabo.
Ivumela ukufakwa kwe- ibhalansi phakathi kokuvikela nokukhiqizwa kwama-radicals wamahhala. Lezi zokugcina akufanele zisuswe kepha zithombalazwe kuphela lapho zikhiqizwa ngokweqile, ukuze kuvinjelwe ubungozi be- ukucindezeleka oxidative.
Una ukondla Ama-antioxidants ampofu angaba imbangela yokungalingani, futhi achaza ukungakwazi komzimba ukulwa ngempumelelo nama-radicals wamahhala.
