methionine) and radical scavengers (Trolox C) suggests a role for radicals in these reactions, though it is unclear whether these arise from direct formation of backbone radicals or via damage transfer from reactive side chain sites (e.g.
Lys amine groups).Cited by: The results from various free radical-scavenging systems revealed that the C. aromaticus had significant antioxidant activity and free radical-scavenging activity.

A scavenger in chemistry is a chemical substance added to a mixture in order to remove or inactivate impurities or unwanted reaction products.
Their use is wide-ranged: 1. In atmospheric chemistry, the most common scavenger is the hydroxyl radical, a short-lived radical. Thus, the function of antioxidant systems is not to remove oxidants entirely, but instead to keep them at an optimum level.
The reactive oxygen species produced in cells include hydrogen peroxide (H 2 O 2), hypochlorous acid (HClO), and free radicals such as the hydroxyl radical.
If a substance you add to your cell can react with at least one of these substances (it does not matter if radical or not) this substance is a "ROS-Scavenger". How the substance is doing the job. May 17, · Q: What’s an “antioxidant”. A: Antioxidants are compounds that offset damage to the body’s cells.
Antioxidants, including certain vitamins, minerals and phytochemicals, defend against injuries caused by free radicals. But what’s a free radical. Simply, free radicals are oxygen molecules floating around in your system that contain an unpaired electric charge.
