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.
