Definition for Vitamin C

From Biology Forums Dictionary

Vitamin C is a water-soluble vitamin that is necessary for normal growth and development.

Water-soluble vitamins dissolve in water. Leftover amounts of the vitamin leave the body through the urine. That means you need a continuous supply of such vitamins in your diet.

Function

Vitamin C is needed for the growth and repair of tissues in all parts of your body. It is used to:

  • Form an important protein used to make skin, tendons, ligaments, and blood vessels
  • Heal wounds and form scar tissue
  • Repair and maintain cartilage, bones, and teeth

Vitamin C is one of many antioxidants. Antioxidants are nutrients that block some of the damage caused by free radicals.

  • Free radicals are made when your body breaks down food or when you are exposed to tobacco smoke or radiation.
  • The buildup of free radicals over time is largely responsible for the aging process.
  • Free radicals may play a role in cancer, heart disease, and conditions like arthritis.

The body is not able to make vitamin C on its own, and it does not store vitamin C. It is therefore important to include plenty of vitamin C-containing foods in your daily diet. For many years, vitamin C has been a popular remedy for the common cold.

  • Research shows that for most people, vitamin C supplements or vitamin C-rich foods do not reduce the risk of getting the common cold.
  • However, people who take vitamin C supplements regularly might have slightly shorter colds or somewhat milder symptoms.
  • Taking a vitamin C supplement after a cold starts does not appear to be helpful.
