There isn't a single chemical formula for antioxidants. That's because "antioxidant" is a broad category describing molecules that can prevent or delay damage caused by oxidation.

What is oxidation? It's a chemical reaction that involves the loss of electrons. This process can cause damage to cells and tissues, leading to various health problems.

Antioxidants are molecules that can donate electrons to free radicals (molecules with unpaired electrons), neutralizing them and preventing oxidative damage.

Here are some examples of common antioxidants and their chemical formulas:

* Vitamin C (Ascorbic Acid): C₆H₈O₆

* Vitamin E (Alpha-tocopherol): C₂₉H₅₀O₂

* Glutathione: C₁₀H₁₇N₃O₆S

* Quercetin: C₁₅H₁₀O₇

* Resveratrol: C₁₄H₁₂O₃

As you can see, there is a wide variety of chemical structures and formulas representing antioxidants.

It's important to remember that while these molecules are beneficial for health, there is no magic bullet. A balanced diet rich in fruits, vegetables, and other antioxidant-rich foods is the best way to obtain the benefits of these compounds.
