       Also known as retinol (the aldehyde derivative retinaldehyde) is a ring having an ester of unsaturated monohydric alcohols, including vitamin A 1, A2 two kinds.
Vitamin A1 and A2 structure similar)
Retinol by plant sources of beta - carotene synthesis in vivo beta - carotene-15 ,15 '- dioxygenase (dioxygenase enzyme)
Catalyzed β - carotene into two molecules of of retinaldehyde (ratinal) retinaldehyde restored retinaldehyde reductase
In order to retinol. Therefore, beta - carotene is also known as the vitamin A of the original.
It is the United States of America in 1913 chemist Davis cod liver extract. It is yellow powder, insoluble in water, soluble in
Fat, oil and organic solvents. Chemically stable, but prone to UV damage, should be stored in a brown bottle.
Vitamin A is feeling low light rhodopsin component of rhodopsin visual cells opsin and `` 11 - cis - depending on
Retinaldehyde dark vision.
Vitamin A is only found in animal food, A1 exist in mammals and saltwater fish, liver, and A2 exist in freshwater fish liver
. Not yet found that vitamin A in the plant tissue. Body lacks vitamin A affect dark adaptation ability, such as children stunted, dry skin, dry
Eye, night blindness.
Normal adult daily vitamin A minimum requirement of about 3500 international units (0.3 micrograms of vitamin A or 0.332 micrograms of acetyl vitamin A phase
When an international units), children of about 2000 to 2500 international units.

The functions of the vitamin A:
Maintain normal visual response. Maintain normal morphology and function of epithelial tissue. Maintain normal bone development. Maintenance of skin cells function
The role, make the skin soft and delicate, wrinkle-wrinkle efficacy. The lack of vitamin A causes the epithelial cell dysfunction, resulting in skin elasticity
Drop, dry, rough and dull.
[Edit this paragraph] vitamin A physiological functions
Vitamin A is a complex organism necessary nutrients, affects almost all tissues of the body in different ways. Despite being one of the earliest hair
Vitamin now, but has not been made about its physiological function fully opened. The purpose of the current knowledge, vitamin A (beta-carotene), the most important physiological functions, including:
1. Maintain visual
Vitamin A can promote the formation of the light-sensitive pigment in the visual cells. All-trans retinaldehyde retinaldehyde isomerase catalyzes 4 - cis - retinal
4 - cis - retinal and opsin combination of rhodopsin (rhodopsin). 4 - cis - retinal into all-trans rhodopsin quality when exposed to light
Retinaldehyde, because of the conformational changes, causing the stimulating effect on the optic nerve, triggering visual. Rhodopsin when exposed to light, unstable, rapidly decomposed into
Opsin and all-trans retinol, and re-start the whole cycle. Vitamin A can debug eyes adapt to the intensity of light, the ability of the outside world, in order to reduce night blindness
The occurrence of disease and vision loss, and maintain normal visual responses contribute to the treatment of a variety of eye diseases (such as dry eye and conjunctivitis, etc.). Vitamin A in the eye
The force was first discovered, is also understood the most features.
2 to promote growth and development
Role in gene regulation. Retinol and retinol equivalent steroid hormones, can promote the synthesis of glycoproteins. Promote the growth, development
Stronger bones, maintenance of hair, teeth and gums healthy.
3. Maintain epithelial structure complete with sound
Retinol and retinoic acid can regulate gene expression, weakened epithelial cell to scaly differentiation, increase the number of epidermal growth factor receptor. Therefore, livelihood
Activin A can regulate the growth of epithelial tissue cells maintain normal morphology and function of epithelial tissue. Keep the skin moist to prevent drying of the skin and mucous membrane horny, not easy
By bacteria damage, contribute to the treatment of acne, pustules, boils, skin surface ulcers embolism; help eliminate age spots; able to keep the tissue or organ surface
Health. A lack of vitamin A causes the epithelial cell dysfunction, leading to decreased skin elasticity, dry, rough and dull.
