Abstract
At concentrations between 0 and 15 mM, Lβlactate increases the oxygen affinity of the hemocyanin in hemolymph dialysates of the crabs Carcinus means and Cancer pagurus without changing the Bohr effect. A possible role of lactate and other anaerobic end products as cofactors regulating the oxygen transport function is suggested.
