Slice an apple in half, and it turns brown. A copper penny unexpectedly turns into green, or an iron nail when left outside, will rust. What do all these activities have in common? These are examples of a method known as oxidation. If the sliced apple is dipped in lemon juice, however, the price at which the apple turns brown is slowed. It is due to the fact the Vitamin C in the lemon juice slows the charge of oxidative damage.

Since its discovery sixty-five years ago, nutrition C has come to be acknowledged as a “wonder worker.” Because of its position in collagen formation and different life-sustaining functions, Vitamin C serves as a key immune machine nutrient and an effective free-radical fighter. This double-duty nutrient has been proven to forestall many illnesses, from everyday illnesses such as the frequent bloodless to devastating illnesses such as cancer.
The water-soluble diet C is acknowledged in the scientific world as ascorbic acid, a time period that surely capacity “without scurvy.” We rely on ascorbic acid for many elements of our biochemical functioning; but human beings are amongst solely a handful of animal species that can't produce their very own furnish of diet C. Like these other animals, together with primates and guinea pigs, we have no preference however to reap this nutrient via meals or our day by day diet.
Vitamin C can beautify the body's resistance to extraordinary diseases, along with infections and sure kinds of cancer. It strengthens and protects the immune gadget by way of stimulating the undertaking of antibodies and immune device cells such as phagocytes and neutrophils.

In this state, they're distinctly reactive and damaging to the entirety that receives in their way. Although free radicals have been implicated in many diseases, they are truly a section of physique chemistry.
As an antioxidant, nutrition C's predominant position is to neutralize free radicals. Since ascorbic acid is water-soluble, it can work each interior and outdoor cells to fight free radical damage. Vitamin C is a remarkable supply of electrons; therefore, it “can donate electrons to free radicals such as hydroxyl and superoxide radicals and quench their reactivity.”
The versatile diet C additionally works alongside glutathione peroxidase (a most important free-radical-fighting enzyme) to revitalize diet E, a fat-soluble antioxidant. In addition to its work as a direct scavenger of free radicals in fluids, then, nutrition C additionally contributes to the antioxidant undertaking in the lipids.
Optimal health, however, requires stability between free radical technology and antioxidant protection. One of the features of Vitamin C is to get and quench these free radicals earlier than they create too plenty of damage.
