WebPalmitoyl-CoA hydrolase (EC 3.1.2.2) is an enzyme in the family of hydrolases that specifically acts on thioester bonds. It catalyzes the hydrolysis of long chain fatty acyl thioesters of acyl carrier protein or coenzyme A to form free fatty acid and the corresponding thiol: palmitoyl-CoA + H 2 O = CoA + palmitate WebAbstract The oxidation of the fatty acids octanoate and palmitate to CO2 and the ketone bodies acetoacetate and D- (-)-3-hydroxybutyrate was examined in astrocytes that were prepared from cortex of 2-day-old rat brain and grown in primary culture to confluence.
