VITAMIN C- (ASCORBIC ACID)

Vitamin C:


Vitamin C is a water-soluble vitamin found naturally in certain foods such as oranges and lemons.

Additionally, Vitamin C is also called L-ascorbic acid and it is not formed in the body on its own, hence it is replenished in the body through diet.

It has many benefits and also helps in normal body functions. It acts as a biosynthesis for collagen fibers.

In fact, It is an antioxidant that helps to heal tissues and reduce inflammation and damage from oxidation.

Vitamin C also helps prevent respiratory infections. Studies have found that it also helps in the treatment of TB.

Vitamin C is helpful in treating cancer. High doses of it may reduce the rate of growth of some types of carcinogenic tissues.

The use of it is very beneficial for our body. Daily intake of this helps our body to fight against diseases.

It is very beneficial in healing wrinkles.

Additionally, It unites the smallest cell in our body.

In fact, It helps in strengthening the blood vessels of the body. Along with this, a substance called collagen, blood vessels, ligaments, cartilage, etc., also need these for manufacture.

Cholesterol levels can also be kept under control by regular use of vitamin C.

Sources of Vitamin C:

Fruits are a major source of vitamin C. In addition, broccoli, potato strawberries, sweet potatoes, leafy greens, mangoes, papaya, watermelon, cauliflower, red chili, cabbage, and pineapple are all important sources of this.

Work:

In order to maintain adequate levels of vitamin C, humans need to consume foods containing vitamin C daily.

It performs many important functions in the body such as the production of collagen, L-carnitine, and some neurotransmitters. It also helps protect proteins and its antioxidant effect may also reduce the risk of certain types of cancer.

Types:

  • Water soluble vitamin.
  • Daily intake recommended–

1.normally:75mg.

2.In conditions like pregnancy, lactation, aged people, smokers : 100-125mg per day because there is an increase in superoxide radical os formed so more ascorbic acid is required to decrease the damage.

  • Sources – Citrus fruits, Green vegetables, Sweet pepper, Guava, Broccoli, Kale etc.
  • Structure – hexose derived monosaccharide, with the presence of acid-enolic hydroxyl groups. The structure is as follows :

  • Functions of vitamin C in body:   
  • It’s a very strong antioxidant, prevents H2O2 formation in our body.
  • Maybe present in reduced or oxidized form and takes part in oxidoreductation and dehydroxylationand in formation of tropocollagen and finally collagen, it basically hydroxylises proline and lysine residues in collagen to produce normal form in teeth, bone, cartilage, skin, capillary walls.
  • Hydroxylation of amino acid in post synthetic modification.
  • Absorption of Iron.
  • Biosynthesis of carnitine (in mitochondrial membrane).
  • Protects -SH groups of protiens from oxidation.
  • Oxidizes Phenylalanine and Tyrosine to synthesize neurotransmittors.
  • As a result of antioxidant functions they activate Vitamin E in active form in our body.

DEFICIENCY

Deficiency of it causes scurvy / scorbutus which includes the symptoms like :

  • Red points on the skin which indicates kidney damage,
  • Big hematomas

  • Kidney stones
  • Diarrhoea
  • Flushed face
  • Headache
  • Increased urinaton
  • Abdominal cramps
  • aNausea
  • Vomit

The small size of the ascorbic acid  means the kidneys cannot hold it in the body.

Even a very low level in the blood serum will cause traces to be present in the urine.
