Chemical structure and physical properties of Retinoic Acid

Retinoic acid, also known as vitamin A acid or tretinoin, is a biologically active form of vitamin A. It plays a crucial role in various physiological processes, including embryonic development, vision, immune function, and skin health. Here is some information about the chemical structure and physical properties of retinoic acid:

Chemical Structure:

Retinoic acid belongs to the class of compounds known as retinoids, which are derivatives of vitamin A.
The chemical formula of retinoic acid is C20H28O2.
Its systematic name is (2E,4E,6Z,8E)-3,7-dimethyl-9-(2,6,6-trimethylcyclohexen-1-yl)nona-2,4,6,8-tetraenoic acid.

Note: Retinoic acid is different from retinol, another form of vitamin A, which is commonly used in skincare products. Retinol is converted into retinoic acid in the skin and then exerts its biological effects.

It’s important to note that while retinoic acid has beneficial effects, it can also be irritating to the skin, and its use should be carefully monitored. If considering the use of retinoic acid for skincare or any medical purpose, it is advisable to consult with a healthcare professional.
