Metabolite Identification
Common Nameall-trans-18-Hydroxyretinoic acid
Descriptionall-trans-18-Hydroxyretinoic acid, also known as All-trans-18-hydroxyretinoic acid or All-trans-All-trans-all-trans-18-hydroxyretinoic 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. 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. In cattle, all-trans-All-trans-all-trans-18-hydroxyretinoic acid is involved in the metabolic pathway called the retinol metabolism pathway.

Enzymes

General function:
Not Available
Specific function:
Involved in the metabolism of retinoic acid (RA), rendering this classical morphogen inactive through oxidation. Involved in the specific inactivation of all-trans-retinoic acid (all-trans-RA), with a preference for the following substrates: all-trans-RA > 9-cis-RA > 13-cis-RA. Generates several hydroxylated forms of RA, including 4-OH-RA, 4-oxo-RA, and 18-OH-RA. Essential for postnatal survival. Plays a central role in germ cell development: acts by degrading RA in the developing testis, preventing STRA8 expression, thereby leading to delay of meiosis. Required for the maintenance of the undifferentiated state of male germ cells during embryonic development in Sertoli cells, inducing arrest in G0 phase of the cell cycle and preventing meiotic entry. Plays a role in skeletal development, both at the level of patterning and in the ossification of bone and the establishment of some synovial joints (By similarity).
