What is a antioxidant easy definition?

What is a antioxidant easy definition?

Listen to pronunciation. (AN-tee-OK-sih-dent) A substance that protects cells from the damage caused by free radicals (unstable molecules made by the process of oxidation during normal metabolism).

What do antioxidants do in motor oil?

Antioxidants are additives designed to prolong the life of a lubricant by increasing the oxidative resistance of the base oil. Antioxidants allow lubricants to operate at higher temperatures than would otherwise be possible without them.

What is antioxidant in polymer?

Antioxidants. Antioxidants inhibit autoxidation that occurs when polymers reacts with atmospheric oxygen. Antioxidants are of great importance during the process stage, with long-term stability at ambient temperature increasingly being supplied by hindered amine light stabilizers (HALs).

What are antioxidants and free radicals?

Antioxidants are nutrients that help minimize free-radical damage to the body. Free radicals are highly reactive compounds that are created in the body during normal metabolic functions or introduced from the environment, such as by exposure to pollution and other toxins.

How do you explain antioxidants to a child?

What are antioxidants? Antioxidants protect the body from damage caused by harmful molecules called free radicals. Many experts believe this damage is a factor in the development of blood vessel disease (atherosclerosis), cancer, and other conditions.

What are antioxidants explain with its example?

Antioxidant: A substance that reduces damage due to oxygen, such as that caused by free radicals. Well-known antioxidants include enzymes and other substances, such as vitamin C, vitamin E, and beta carotene, which are capable of counteracting the damaging effects of oxidation.

What is antioxidant PDF?

Antioxidants are a class of chemical substances naturally found in our food which can prevent or reduce the oxidative stress of the physiological system. Based on their solubility, antioxidants are broadly categorized into two groups: water soluble and lipid soluble.

What are antioxidants give an example?

Examples of antioxidants include vitamins C and E, selenium, and carotenoids, such as beta-carotene, lycopene, lutein, and zeaxanthin.

What are antioxidants with example?

Examples of antioxidants include vitamins C and E, selenium, and carotenoids, such as beta-carotene, lycopene, lutein, and zeaxanthin. This fact sheet provides basic information about antioxidants, summarizes what the science says about antioxidants and health, and suggests sources for additional information.

What benefits do antioxidants have?

A diet high in antioxidants may reduce the risk of many diseases (including heart disease and certain cancers). Antioxidants scavenge free radicals from the body cells and prevent or reduce the damage caused by oxidation. The protective effect of antioxidants continues to be studied around the world.

What is the meaning of antioxidant in science?

Science definitions for antioxidant. antioxidant. A chemical compound or substance that inhibits oxidation. Certain vitamins, such as vitamin E, are antioxidants and may protect body cells from damage caused by the oxidative effects of free radicals.

How antioxidants work step by step?

Steps of how antioxidants work 1 A molecule loses an electron. This creates reactive oxygen species… 2 The free radical searches for an electron. When it steals one from a cell, this creates a chain reaction. 3 An antioxidant works by giving a free radical an electron.

How do antioxidants cause damage?

Damage results from this chaos. An antioxidant works by giving a free radical an electron. This neutralizes it, meaning it longer needs to steal electrons from cells. In order for antioxidants to work, the free radicals need to encounter them before the body’s cells.

What do Antioxidants do to neutralize free radicals?

They donate electrons to free radicals, which neutralizes them and prevents them from causing harm. Bottom Line: Antioxidants are molecules that fight damage by free radicals, unstable molecules that can harm cellular structures. Antioxidants do this by giving electrons to the free radicals and neutralizing them.
