Abstract
Cytochrome c oxidase activity, carnitine concentration and oxidation rates of pyruvate
and palmitate were determined in homogenates of various types of human skeletal muscle.
Cytochrome c oxidase activity appeared to be closely related to the pyruvate oxidation
rate, but its correlation with palmitate oxidation was less distinct.
Trunk muscles oxidize less palmitate and have a lower cytochrome c oxidase activity
per mg homogenate protein than leg muscles; soleus muscle biopsies showed higher activities
than those of other leg muscles. Based on cytochrome c oxidase activity no large differences
are found in palmitate oxidation rate between various types of human muscle.
Cytochrome c oxidase activity and palmitate oxidation rate of muscles do not show
an age dependency.
The carnitine concentration is similar in all kinds of human skeletal muscle.
