Abstract

The pure mitochondrial fraction obtained from human skeletal muscle did not show coupled L-lactate (+ NAD) oxidation, but this function could be restored by addition of LDH. Thus the "direct", coupled oxidation of L-lactate described earlier (Popinigis et al., 1990. International Perspectives in Exercise Physiology, Human Kinetics Books, pp. 132-133) should be attributed to contaminations.
