What can vitamin A do to the body what is it good for?

Variant: retinol

A fat-soluble vitamin that cannot be synthesized by mammals and other vertebrates and must be provided in the diet. Green plants contain precursors of the vitamin, notably carotenes, that are converted to vitamin A in the intestinal wall and liver. The aldehyde derivative of vitamin A, retinal, is a constituent of the visual pigment rhodopsin. Deficiency affects the eyes, causing night blindness, xerophthalmia, and eventually total blindness. The role of vitamin A in other aspects of metabolism is less clear.

Answer 3

Vitamin A is a fat soluble vitamin that is involved in several areas of our health. It helps us with light-dark vision and with color vision; it helps maintain the health of cells that line the surfaces of the lungs, intestines, stomach, vagina, urinary tract, bladdar, eyes and skin (Epithelial cells); it helps with growth, development and reproduction; and it may play a role in helping to prevent Heart disease and cancer.
Like most vitamins, the existence of Vitamin A in our bodies is to help us maintain good health.

Vitamin A is very important for immune system of the human body. Skin, lining the digestive and urinary tracks, contains Retinol. This lining restricts the entrance of various infectious microbes and other harmful materials. Retinoic acid and vitamin A are also essential for the formation of white blood cells, which are very important for fighting different infectious materials, hence strengthening the immune system. Red blood cells help in absorption of oxygen. These cells are formed from the stem cells which themselves are formed by the help of retinoids. Different studies suggest that Vitamin A is helpful in reducing growth of cancer in different parts of human body for example liver, breast, colon and skin.

Retinoic Acid, a special form of Vitamin A, plays an important role in the structure of human genes. It can also influence transcription rate of the gene, which can effect formation of other proteins formed in human body. Retinoic Acid is also very important for cellular differentiation. Therefore vitamin A plays a key role in growth of human body. Retinoic acid and Retinol are helpful in development of embryo.

Vitamin A is very important for human sight. After complex chemical reactions, Retinol gets binds with a protein called opsin to form Rhodopsin. Rod cells, which are inside human eye, contain Rhodopsin which aids viewing in low light conditions.

Vitamin A Deficiency

Deficiency of Vitamin A can weaken the immune system, hence making human body prone to infections. Its deficiency may also lead to respiratory problems. Acute deficiency of Vitamin A in children may lead to night blindness. Mild deficiency of vitamin A may cause dryness of skin and eyes and Bitot's spots
