Metabolite Identification
Common Name9-cis-Retinol
DescriptionVitamin a, also known as (13cis)-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, vitamin a is considered to be an isoprenoid lipid molecule. Vitamin a is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Vitamin a exists in all living organisms, ranging from bacteria to humans. Vitamin a participates in a number of enzymatic reactions, within cattle. In particular, Vitamin a and acetyl-CoA can be converted into retinyl ester through the action of the enzyme diacylglycerol O-acyltransferase 1. In addition, Vitamin a and acetyl-CoA can be converted into retinyl ester through the action of the enzyme acyl-CoA wax alcohol acyltransferase 1. In cattle, vitamin a is involved in the metabolic pathway called the retinol metabolism pathway. Vitamin a is a potentially toxic compound. Vitamin a has been found to be associated with several diseases known as pregnancy, hemodialysis, and thyroid cancer; also vitamin a has been linked to the inborn metabolic disorders including abetalipoproteinemia.

Enzymes

General function:
Lipid transport and metabolism
Specific function:
Retinoids dehydrogenase/reductase with a clear preference for NADP. Displays high activity towards 9-cis, 11-cis and all-trans-retinal. Shows very weak activity towards 13-cis-retinol. Also exhibits activity, albeit with lower affinity than for retinaldehydes, towards lipid peroxidation products (C9 aldehydes) such as 4-hydroxynonenal and trans-2-nonenal. May play an important function in photoreceptor cells to detoxify 4-hydroxynonenal and potentially other toxic aldehyde products resulting from lipid peroxidation. Has no dehydrogenase activity towards steroids.
