What role does oxidation play in cellular aging?
Oxidation is the reaction of cellular molecules with oxygen, from which free radicals are formed, waste products of metabolic reactions. Free radicals, in turn, attack our cells giving rise to a chain reaction that causes damage to biomolecules and the aging of cells and tissues.
A healthy organism is able to defend itself from the presence of free radicals thanks to antioxidants.
What is the action of antioxidants in anti-aging processes?
An antioxidant molecule is capable of preventing the oxidation of other molecules, neutralizing the action of free radicals, which are transformed into less harmful and easier to eliminate molecules.
The antioxidants in our body work as a defense system protecting us from free radicals and a purification system. In addition, they help build and repair the body’s structures.
Oxidation and free radicals therefore cause both aging of cellular structures and damage to structural biomolecules such as collagen and elastin.
On our skin the damage can become visible, for example through the formation of wrinkles and the loss of elasticity.
