Abstract

Since living organisms contain several free radicals under physiological conditions, there must exist innate mechanisms keeping their reactions under control in situations like electron transport, melanin production or photosynthesis. Molecular structures of vital importance like the cell membrane. DNA and proteins have constituents which are very sensitive to radical reaction, such as the a-methylene carbon atom of PUFAs as well as allylic hydrogen, and the thymidine base.
