Common Name4-Hydroxyretinoic acid
Description4-Hydroxyretinoic acid, also known as 4-hydroxy-13-cis-retinoate or 4-OH-retinoate, 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. 4-Hydroxyretinoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Within humans, 4-hydroxyretinoic acid participates in a number of enzymatic reactions. In particular, 4-hydroxyretinoic acid can be biosynthesized from all-trans-retinoic acid; which is catalyzed by the enzyme cytochrome P450 26A1. In addition, 4-hydroxyretinoic acid can be converted into 4-oxo-retinoic acid through the action of the enzyme cytochrome P450 26A1. A retinoid that consists of all-trans-retinoic acid bearing a hydroxy substituent at position 4 on the cyclohexenyl ring. 4-Hydroxyretinoic acid was first documented in 1988 (PMID: 2851384). In humans, 4-hydroxyretinoic acid is involved in retinol metabolism (PMID: 1932598) (PMID: 1538719) (PMID: 10702251) (PMID: 1328295).
