  • Title: L-lactate oxidation by skeletal muscle mitochondria.
    Author: Szczesna-Kaczmarek A.
    Journal: Int J Biochem; 1990; 22(6):617-20. PubMed ID: 2379665.
    Abstract:
    1. Mitochondria isolated from rat skeletal muscle possess lactate dehydrogenase which is involved in direct oxidation of L-lactate in the presence of external NAD. 2. L-lactate oxidation can be stimulated in a reversible manner by ADP. 3. Mitochondrial lactate oxidation is sensitive to oxamate-inhibitor of LDH, alpha-cyano-3-hydroxy-cinnamate-pyruvate translocase inhibitor and respiratory chain inhibitors (rotenone, antimycin A, KCN). 4. In the same conditions the mitochondria did not oxidize pyruvate in the absence of malate, whereas, oxidize pyruvate plus external NADH in an uncoupling manner.
