The association-dissociation behaviour in Todarodes sagittatus hemocyanin has been studied by sedimentation velocity measurements at different pH values and in the absence and presence of a number of anions and cations. In the absence of salts the sedimentation pattern is dominated (about 1002) by a relatively low M.W. species (20 S), while 10 mM CaCl2 and increasing pH (above 65) stabilize a larger (30 S) species. The above data are used as a basic to explain some physiological questions concerning the nutritional habits of these animals.

Abstract
The association-dissociation behaviour in Todarodes sagittatus hemocyanin has been studied by sedimentation velocity measurements at different pH values and in the absence and presence of a number of anions and cations. In the absence of salts the sedimentation pattern is dominated (about 1002) by a relatively low M.W. species (20 S), while 10 mM CaCl2 and increasing pH (above 65) stabilize a larger (30 S) species. The above data are used as a basic to explain some physiological questions concerning the nutritional habits of these animals.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
