Functional differences in lipid metabolism in resting skeletal muscle of various fiber types

The interaction between fatty acid oxidation and deposition with the muscle lipid oxidation was analyzed by pulse studies of incubated epitrochlearis, flexor digitorum and soleus muscles. Analysis of muscle lipid oxidation indicated the constant incorporation of pamitate into triacylglycerols (TGs) in skeletal muscles during lipid oxidation. Furthermore, the soleus muscle exhibited the highest degree of lipid potential while the flexor digitorum muscle was the least oxidative muscle. However, the incorporation of palmitate into TGs was highest in the flexor digitorum longus muscle.
