what is a antioxident?

Answer 1

HI,

An antioxidant is a chemical that reduces the rate of particular oxidation reactions in a specific context, where oxidation reactions are chemical reactions that involve the transfer of electrons from a substance to an oxidising agent.

Antioxidants are particularly important in the context of organic chemistry and biology. All living organisms maintain a reducing environment inside their cells, all cells contain complex systems of antioxidants to prevent chemical damage to the cells' components by oxidation. These antioxidants include glutathione and ascorbic acid and are substrates for enzymes such as peroxidases and oxidoreductases.

A diet containing polyphenol antioxidants from plants is required for the health of most mammals, since plants are an important source of organic antioxidant chemicals. Antioxidants are widely used as ingredients in dietary supplements that are used for health purposes such as preventing cancer and heart disease. However, while many studies have suggested benefits for antioxidant supplements in laboratory experiments, several large clinical trials have failed to clearly demonstrate a benefit for the formulations tested, and excess supplementation may be harmful. It is logical to assume that a one dimensional approach to dietary supplementation with one specific antioxidant is not a panacea, since a broad diet rich in phytonutrients will yield thousands of different polyphenol antioxidants available for metabolism.

Answer 2

Firstly ,should know what is "oxidents".
They are metabolites of oxidative reactions in the body,including superoxide free radicles,hydrogen peroxide and so on.
They are potent oxidizing agents and they damage the cells by oxidizing it's components.It's said tht they are responsible for aging and cancers.
Antioxidents are substances that help to reduce the oxidents.
Famous antioxident vitamins are vitamin A,C & E.There are many other antioxidents too.

Answer 3

Antioxidants are chemical substances that decreases the build up of free radicals in the body. Free radicals damage cells functions and somewhat responsible for the growth of neoplastic cells (cancer cells). Vitamin E and C are potent antioxidants.

Answer 4

its basically something that is good for health and the usually gives the apperance of healthy younger skin

Answer 5

OUR FOOD CONTAINS MANY TOXIC ELEMENTS WHICH HARMS OUR BODY'S SYSTEM OF WORKING.
YOU DRINK 4 PEGS OF WHISKEY YOU CAN'T RUN.
THE BODY'S SYSTEM GOES HAYWIRE.
SO ALSO TOXIC ELEMENTS HARM THE BODY IN A DIFFERENT WAY.
ANTIOXIDANTS REMOVES OR NEUTRALISE'S THIS.
