Spectrophotometric Studies of Penetration
The rate of diffusion through the non-aqueous layer of the protoplasm depends largely on the partition coefficients mentioned above. Since these cannot be determined we have employed an artificial system in which chloroform is used in place of the non-aqueous layer of the protoplasm. The partition coefficients may be roughly determined by shaking up the aqueous solutions with chloroform and ana...
متن کاملSpectrophotometric Studies on Intact Muscle
The concentrations of the components of the respiratory chain were determined in a variety of intact skeletal muscles by a method of spectrophotometric observation of the transmitted light. In the case of the toad sartorius, these measurements were checked against isolated mitochondrial suspensions prepared from toad skeletal muscles. The relative concentrations of the respiratory components we...
متن کاملSpectrophotometric Studies of Penetration of Dyes
Spectrophotometric measurements show that the non-medullated nerve of a lobster claw is capable of absorbing methylene blue, azure B, or acid fuchsin dissolved in sea water but this does not necessarily imply that the dyes penetrate into the interior of the nerve.
متن کاملSpectrophotometric studies on lysine monooxygenase, a flavoprotein.
The spectral changes of the enzyme-hound FAD were investigated in the anaerobic and aerobic reactions of lysine monooxygenase, a flavoprotein. Under anaerobic conditions, the enzyme FAD was fully reduced with lysine via a transient intermediate having a broad absorption band in the long wavelength region. This anaerobic species was presumably involved in the dehydrogenation of lysine leading to...
متن کاملSpectrophotometric studies of the Zimmermann reaction.
THE ZIMMEBMANN REACTION (12-14) is well known to all workers in the field of ketosteroid analysis. The basic reaction is that which takes place between various ketosteroids and m-dinitrobenzene (DNB) in strongly alkaline solution to produce a characteristic pink to violet color showing a maximal absorbance between 510 and 530 m . Two major modifications of the reaction are known. That of Callow...
