| Common Name | 4-Oxoretinol |

| Description | 4-Oxoretinol, also known as 4-oxo-rol or 4-oxovitamin A1, 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-Oxoretinol is an extremely weak basic (essentially neutral) compound (based on its pKa). 4-Oxoretinol can be biosynthesized from vitamin a through the action of the enzyme cytochrome P450 26A1. In humans, 4-oxoretinol is involved in retinol metabolism. 4-Oxoretinol was first documented in 1996 (PMID: 9110564). A retinoid that is all-trans-retinol in which the hydrogens at position 4 have been replaced by an oxo group (PMID: 9581846). |
