...-hydroxycinnamate, a known inhibitor of lactate transport. These results suggest that lactate is relatively impermeant to the trout white muscle membrane and any lactate loss occurs via passive diffusion. This resistance to lactate diffusion can explain why trout muscle retains lactate post-exercise, despite...

... uptake rates for several concentrations in the physiological range (i.e. 0 2-20 mmol 1 −1 ) yielded a linear double reciprocal plot (1/v VS l/[lactate]) that passed through the origin. Lactate uptake was not inhibited by known inhibitors of carrier-mediated lactate transport (e.g. 5 mmol 1 −1 α-cyano-4...
