| Description | 9-Cis-Retinol 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. Thus, 9-cis-retinol is considered to be an isoprenoid lipid molecule. 9-Cis-Retinol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Within humans, 9-cis-retinol participates in a number of enzymatic reactions. In particular, 9-cis-retinol can be converted into 9-cis-retinal; which is catalyzed by the enzyme retinol dehydrogenase 11. In addition, 9-cis-retinol can be converted into 9-cis-retinal; which is mediated by the enzyme retinol dehydrogenase 11. In humans, 9-cis-retinol is involved in retinol metabolism. Outside of the human body, 9-cis-Retinol is found, on average, in the highest concentration within a few different foods, such as tea leaf willows, walrus, and sourdocks and in a lower concentration in pummelo, green zucchinis, and amaranths. 9-Cis-Retinol has also been detected, but not quantified in, several different foods, such as sea-buckthornberries, vanilla, opium poppies, meringues, and ascidians. This could make 9-cis-retinol a potential biomarker for the consumption of these foods. (13Z)-Retinol was first documented in 1997 (PMID: 9115228). A retinol in which the double bond at position 9 has cis configuration, whilst the remaining acyclic double bonds have trans configuration (PMID: 15572038) (PMID: 11140907). |
