Abstract
- 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.
摘要
- 经测定，抹香鲸高铁肌红蛋白在干重基础上含铁量为0.308%，相应的分子量为18130。该固体吸收水分至平衡状态后，经检测含铁量为0.280%。2. 给出了酸性高铁肌红蛋白、Fe(+)(H₂O)及其共轭碱Fe-OH以及氟化物和氰化物配合物在200 - 2500mμ范围内的吸收光谱。还包括了高铁肌红蛋白 - 一氧化碳（Fe(II)-CO）在可见光区域的数据。3. 已发现鲸和马的肌红蛋白之间存在细微的光谱差异，特别是温度对Fe-OH可见吸收光谱的影响。
