Oxidative Stress and Antioxidant Defense

Tobacco smoke, redox metals, and nonredox metals, such as iron, cadmium, chrome, and arsenic, are also involved in carcinogenesis and aging by generating free radicals or binding with thiol groups. Formation of 8-OH-G is the best-known DNA damage occurring via oxidative stress and is a potential biomarker for carcinogenesis.

Moreover, the intracellular accumulation of ROS or RNS would eventually cause macromolecule damage, activity decrease, and even cell death (Zorov et al., 2014). Luckily, several mechanisms are used by bacteria to withstand the oxidative stress damage caused by ROS such as the production of detoxifying enzymes (Staerck et al., 2017).

Enzymatic Antioxidants. Stress results in the production of ROS species which promote oxidative damage in biological systems ( Reddy et al., 2004, Samarah et al., 2006 ). The detoxification of ROS exist in all plants and can be divided into enzymatic (SOD, APX, POX, GR, etc.) and nonenzymatic (ascorbic acid, flavanones, anthocyanins, etc.).

The oxidative stress process contributes to the abnormal cellular function caused by a group of molecules known as free radicals, including reactive oxygen species (ROS) (Aseervatham et al. 2013; Harman 1956; Kumar et al. 2018).The ROS can affect DNA, lipid, and protein, and may reduce antioxidant enzymes (Sadeghi et al. 2019a, 2019b).There are two different free radical generation routes.
