Question

Define Antioxidants.

Answer 1

Hint: In chemistry, many compounds help to control free radicals, which may be a cause of exploitation. And during exploitation can change from one substance to another. In some reactions, the cell may damage the organism.

Complete answer:
Firstly, take a look at the compound, free radical, and so on,
- Compounds: It is a type of chemical substance made by many different atoms and molecules by a chemical bond.
- Free radicals: It is an atom, molecule, or ion that is unpaired, which means they have not any pair. They are singly available in their valence shell.
Now, let's have a look at how these terms are important for antioxidants.
- Antioxidant: When the compounds prevent oxidation these compounds are known as antioxidants.
It uses biologically and chemically both.
Example - Ascorbic acid, thiols, etc.
-In plants and animals, antioxidants help to balance oxidative stress.
-In industry, it helps to prevent cosmetic and food products.
Antioxidant divided into two parts
1. Hydrophilic
2. Lipophilic
- Hydrophilic: Those antioxidants soluble in water are known as Hydrophilic.
- Lipophilic: Those antioxidants soluble in fat and oil are known as Lipophilic.
- Oxidation: It is a chemical reaction that is able to produce unpaired electrons means free radical.

Note:
Chain reaction: It is a series of reactions additional reaction takes place due to reactive product or by-product.
Cell: It is the basic functional, structural, and biological unit of an organism. Each atom orbit divides into shells. The molecule is connected by a covalent bond. An ionic compound is bounded by an ionic bond. Inter metallic bounded by the metallic compound.
