Lignin, the second most abundant biopolymer on Earth after cellulose, plays a crucial role in plants by providing rigidity and protection against environmental stress. This natural polymer functions as an effective antioxidant primarily due to its complex and varied phenolic structure. Its primary mechanism involves scavenging harmful free radicals to stabilize cellular components and inhibit chain reactions caused by oxidative agents.

Beta-carotene is a powerful pigment found in many red, orange, and yellow fruits and vegetables, and numerous studies suggest that consuming it through diet is associated with lower markers of oxidative stress. This article explores what is the mechanism of action of beta carotene antioxidant and how its function is surprisingly complex and dependent on cellular conditions.

According to the Linus Pauling Institute, vitamin C is a potent reducing agent, meaning it readily donates electrons to other molecules. This fundamental chemical property explains how vitamin C neutralises free radicals and defends against the cellular damage of oxidative stress.

According to the National Institutes of Health, vitamin E acts as a fat-soluble antioxidant, protecting cells from damage caused by free radicals. This essential nutrient, primarily in the form of alpha-tocopherol, is a crucial line of defense against the oxidative stress that contributes to numerous chronic diseases.

With over 8,000 different types identified, polyphenols are abundant plant compounds known for numerous health benefits. A key function is their potent antioxidant activity, and understanding the precise mechanism of action of polyphenols as antioxidants is crucial for appreciating their protective effects.
