Med Clin North Am ; Certain turtle species have been found to be capable of tolerating high levels of lactic acid without suffering the effects of lactic acidosis.

Diabetes Obes Metab, 3pp. Glycolysis coupled with lactate production is neutral in the sense lcatica it does not produce excess hydrogen cations; however, pyruvate production does produce them.

SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field. Hypoxia certainly causes both a buildup of lactate and acidification, and lactate is therefore a good “marker” of hypoxia, but lactate itself is not the cause of low pH. A review of history, pharmacodynamics and therapy.
