One of the transformation products formed from stearoyl CoA by the soluble enzymes of rat liver homogenate has been identified as 3 hydroxyoctadecanoic acid. The chirality of this acid obtained from incubation of [1 14C]stearoyl CoA with the 105,000 g soluble enzymes of rat liver has been determined. After 10 and 20 min of incubation 70% of the L(+) and 30% of the D(-) enantiomer are formed, whereas racemic 3 hydroxyoctadecanoic acid is isolated after 90 min of incubation. These results suggest either that an epimerizing enzyme is present in the soluble fraction or that 2 enzymes, each specifically forming one of the 2 enantiomers, are present.
