beta-Hydroxy acyl-CoA inhibition of mitochondrial ATP production.

Abstract

beta-Hydroxypalmitoyl-CoA and beta-hydroxystearoyl-CoA were synthesized, purified and quantitated. beta-Hydroxypalmitoyl-CoA and beta-hydroxystearoyl-CoA instantly and reversibly inhibited oxidative phosphorylation by rabbit heart mitochondria oxidizing pyruvate. [8-14C]ADP uptake studies showed that the beta-hydroxy acyl-CoA species linearly inhibited the… (More)
