Metabolite Identification
Common Name3-Oxooctadecanoyl-CoA
Description3-Oxooctadecanoyl-CoA is a metabolite intermediate in the microsomal fatty acid chain elongation system. Microsomal electron-transport components NADPH-cytochrome P450 reductase (EC 1.6.2.4) and cytochrome b5 (EC 1.6.2.2) participate in the conversion from 3-Oxooctadecanoyl-CoA to beta-hydroxystearoyl-CoA, the first reductive step of the microsomal chain elongating system initiated by NADPH.

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
Catalyzes the transformation of estrone (E1) into estradiol (E2), suggesting a central role in estrogen formation. Its strong expression in ovary and mammary gland suggest that it may constitute the major enzyme responsible for the conversion of E1 to E2 in women. Also has 3-ketoacyl-CoA reductase activity, reducing both long chain 3-ketoacyl-CoAs and long chain fatty acyl-CoAs, suggesting a role in long fatty acid elongation.
