Vitamin A is an alcohol (retinol), but can be converted into an aldehyde (retinal), or acid (retinoic acid).

Active Form
Vitamin A consists of three biologically active molecules which are collectively known as retinoids.
1. Retinol: Primary alcohol (CH2OH) containing form
2. Retinal: Aldehyde (CHO) containing form
3. Retinoic acid: Carboxyl (COOH) containing form
