Sources of Oxidants and Antioxidants

This template shows the classification of oxidants into endogenous sources, such as mitochondrial and endoplasmic reticulum electron transport chains, NADPH oxidase, and nitric oxide synthase, and exogenous sources, such as particulates, radiation, smoke, ozone, and nitrogen/sulfur oxides. It also shows antioxidants divided into enzymatic types, including superoxide dismutase, catalase, thioredoxin, and peroxiredoxin, and nonenzymatic types, including vitamin C, flavonoids, carotenoids, glutathione, and vitamin E, each paired with its chemical structure or icon.
