Self-association of sperm whale metmyoglobin
Archives of Biochemistry and Biophysics, 1984The solution behavior of sperm whale metmyoglobin in 0.15 I phosphate-chloride buffer, pH 7.2, has been examined by sedimentation equilibrium, frontal gel chromatography, and sedimentation velocity. Results obtained from all three studies are shown to be consistent with a self-association model in which dimerization of the myoglobin is governed by an ...

The International Whaling Commission (IWC) is holding a special meeting in Japan next week. Two major tasks for the meeting will be to set catch limits for sperm whale stocks in the North Pacific and to review the status and catch limits of sperm whales in the Southern Hemisphere.

Stability properties of sperm whale oxymyoglobin
Archives of Biochemistry and Biophysics, 1983Sperm whale oxymyoglobin was isolated directly from muscle and was examined for its stability properties over the wide range of pH 5-13 in 0.1 M buffer at 25 degrees C. The remarkable pH dependence for the autoxidation rate was analyzed using the kinetic equation derived in terms of nucleophilic displacement processes of O-2 from oxymyoglobin by the ...

Ontogenesis of the sperm whale brain
The Journal of Comparative Neurology, 1998The development of the sperm whale brain (Physeter macrocephalus) was investigated in 12 embryos and early fetuses to obtain a better understanding of the morphological and physiological adaptations in this most exotic cetacean concerning locomotion, deep diving, and orientation.

SOCIETY FOR INTEGRATIVE AND COMPARATIVE BIOLOGY MEETINGPHOENIX, ARIZONA-- At the Society for Integrative and Comparative Biology meeting, held here from 3 to 7 January, researchers described male tubeworms with a distinctly odd but highly targeted development: They fail to mature, except with respect to their ability to produce sperm. ([Read more][1].)
