Optical Rotatory Dispersion of Human Carbonic Anhydrases: Cotton Effects and Aromatic Absorption Bands.
Three distinct carbonic anhydrases, now denoted as A, B, and C, have been separated from human erythrocytes, by several different methods.1-4 Enzyme A is present in small amount and with low specific activity, B in much larger amount but also with low specific activity, C in small amount but with high specific activity.5 All three enzymes have molecular weights close to 30,000 and each contains...
متن کاملQuantum optical rotatory dispersion
The phenomenon of molecular optical activity manifests itself as the rotation of the plane of linear polarization when light passes through chiral media. Measurements of optical activity and its wavelength dependence, that is, optical rotatory dispersion, can reveal information about intricate properties of molecules, such as the three-dimensional arrangement of atoms comprising a molecule. Giv...
متن کاملNeutron Scattering of Aromatic and Aliphatic Liquids
Organic solvents, such as cyclohexane, cyclohexene, methylcyclohexane, benzene and toluene, are widely used as both reagents and solvents in industrial processes. Despite the ubiquity of these liquids, the local structures that govern the chemical properties have not been studied extensively. Herein, we report neutron diffraction measurements on liquid cyclohexane, cyclohexene, methylcyclohexan...
متن کاملOptical Rotatory Dispersion of Catalase.
It is well recognized that the measurements of optical rotatory dispersion of proteins with strong absorption bands are extremely difficult because of the diminishing intensity of the emergent light. Until very recently, these studies were made possible only by improving the light source and also frequently by a wide opening of the slit width on the monochromator at the expense of spectral puri...
متن کاملPhenylethanoid and aliphatic alcohol glycosides from Acanthus ilicifolius.
A phenylethanoid glycoside (ilicifolioside A) and an aliphatic alcohol glycoside (ilicifolioside B), have been isolated from the aerial parts of Acanthus ilicifolius, together with eight known compounds. Their structures were determined from spectroscopic analyses.
