Vitamin A

What is Vitamin A?

The chemical name of vitamin A is retinol, which is the first vitamin to be discovered. There are two types of vitamin A. One is vitamin A alcohol (retionl), which is the original form of vitamin A (existing only in animal foods); the other is carotene, which is converted into vitamin A preformed substance (provitaminA) in the body. Ingested from plant and animal foods); The measurement units of vitamin A are USP units (UnitedStatesPharmocopea), IU units (International Units), RE units (Retinol Equivalents), etc.

Vitamin A (vitaminA), also known as retinol (its aldehyde derivative retinal), is an unsaturated monohydric alcohol with an ester ring. Vitamin A includes vitamin A1 and A2. (Vitamin A1 and A2 have similar structures). Retinol can be synthesized from plant-derived β-carotene. Under the catalysis of β-carotene-15,15′-dioxygenase (dioxygenase) in the body, β-carotene can be converted to β-carotene. Converted into two molecules of retinal (ratinal), retinal is reduced to retinol under the action of retinal reductase. Therefore, β-carotene is also called provitamin A.
