| Common Name | all-trans-18-Hydroxyretinoic acid |
|---|
| Description | All-trans-18-Hydroxyretinoic acid, also known as 18-hydroxyretinoate or 18-hydroxy-all-trans-retinoic acid, belongs to the class of organic compounds known as retinoids. These are oxygenated derivatives of 3,7-dimethyl-1-(2,6,6-trimethylcyclohex-1-enyl)nona-1,3,5,7-tetraene and derivatives thereof. A retinoid that consists of all-trans-retinoic acid bearing an hydroxy substituent at position 18. All-trans-18-Hydroxyretinoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. All-trans-18-hydroxyretinoic acid can be biosynthesized from all-trans-retinoic acid through its interaction with the enzyme cytochrome P450 26A1. all-trans-18-Hydroxyretinoic acid was first documented in 1991 (PMID: 1932598). In humans, all-trans-18-hydroxyretinoic acid is involved in retinol metabolism. |
