Absorption spectra of sperm-whale ferrimyoglobin
Copyright policy )Absorption spectra of sperm-whale ferrimyoglobin
1. Sperm-whale ferrimyoglobin was found to contain 0.308% of Fe, on a dry weight basis, corresponding to a molecular weight of 18130. The solid takes up moisture to an equilibrium state, and was then assayed to contain 0.280% of Fe. 2. Absorption spectra are presented for acidic ferrimyoglobin, Fe(+)(H(2)O), and its conjugate base, Fe-OH, as well as for the fluoride and cyanide complexes, within the range 200-2500mmu. Data for ferromyoglobin-carbon monoxide, Fe(II)-CO, in the visible region are also included. 3. Minor spectral differences have been found between whale and horse myoglobins, particularly in the effect of temperature on the visible-absorption spectrum of Fe-OH.
