Vitamin A

Vitamin A is an organic compound that is fat soluble. Its dietary prerequisites are low. But, its deficiency causes some disorders. Nutrient An is discovered uniquely in creature tissues. The active vitamin in plant tissues is in the form of pro vitamin. Retinal, an active Mineral AA from beta carotene, is produced in the liver. Retinal is a primary alcohol and aldehyde. Oxidation of retinol produces retinol acid.

The human body converts beta carotene into retinol (Mineral A). In short, beta carotene is a precursor of retinol. Retinol is essential for healthy skin, digestive mucosa, immune system and eye health and vision. It is available from the diet in the form of beta carotene.

Vitamin A source:

Animal sources: 

Butter, milk, cheese and mayonnaise, cod liver oil.

Vegetable sources: 

Tomatoes, carrots, spinach, broccoli, cilantro, chillies, green leafy vegetables, mangoes, papayas, almost all colorful vegetables and fruits.

Adult men and women need about 3,000 international units (IU) of Mineral A every day. Pregnant and lactating women as well as patients with liver disease need more Mineral A.

Nutrient An is assimilated from the digestive organs alongside fats. Supplement An is taken care of in the liver In the form of retinol, it is available from the liver as needed.

Function of Vitamin A: 

Vitamin A is essential for proper physical growth, reproduction and vision. Vitamin A plays a key role in the Wald Visual Cycle or Rhodopsin cycle in the functioning of the eyes. There are two sorts of cells in the retina: pole and cones. Mineral A is essential for the normal functioning of these cells. When a person moves from bright light to dim light, vision decreases in a few minutes. This is when rhodopsin is resynthesized and vision is improved.

Mineral A plays an important role in other biochemical functions, such as bone and tooth formation, skin and mucous membrane formation, and metabolism.

Vitamin A Deficiency: 

Symptoms of Mineral A Deficiency do not appear early. Mineral A is adequately stored in the liver. Therefore, if you do not have Mineral A in your diet for a long time, you will be deficient in it.

Mineral A deficiency leads to visual impairment and night blindness and color blindness. It does not appear clear in the darkness of night as well as in dim light. Long-term deficiency of vitamin A causes damage to the cells in the retina. Inflammation of the front part of the iris of the eye. The cornea becomes dry (Xerophthalmia). A sore on the scalp causes it to shrink and then complete blindness.

Mineral A deficiency causes dry skin and itching. It also aggravates liver and kidney diseases. Keratinization of the urethra and respiratory tract. Accumulation of such dead tissue increases the risk of bacterial infection.

Vitamin A Excess: 

Consumption of Vitamin A in excess can lead to changes in metabolism of fat soluble vitamins, bone swelling or bone pain, liver enlargement, hair loss, irritability. Symptoms of poisoning also occur. Excess vitamin A in the diet does not affect the body. However, over-consumption of the liver of mammals, such as fish and seals, can lead to poisoning. If it is diagnosed in time, avoiding such substances in the diet will reduce the poisoning over time.
