摘要:

AbstractThe electrophoretic mobilities of bivalent cations (Ca++and Sr++) were measured in the presence of a linear anionic polysaccharide extracted from cartilage—chondroitin sulfate. The experimental results were analyzed according to Manning's treatment which involves only the charge‐density parameter ξ related to the structure of the polyion and the charge of the counterion. The comparison between the electrophoretic mobility and the self‐diffusion coefficient enabled us to determine the apparent charge of the counterions in the different domains of concent

摘要:

AbstractInteraction of toluidine blue with helical and randomly coiled poly(α,L‐glutamic acid) was studied with absorption spectra, titration, and electric‐field pulse measurements. The obtained values of various parameters for the helical form of poly(α,L‐glutamic acid)differed from those for its coiled form. The difference of parameters in these two forms of poly(α,L‐glutamic acid) was attributed to differences of the binding mechanism in both forms. Furthermore, the binding of toluidine blue to poly(α,L‐glutamic acid) was considered to be due to hydrogen binding in the helical conformation and ionic interaction in the coiled conformation o

摘要:

AbstractThe Raman Spectra of bovine serum albumin have been obtained in the solute state, in alkaline and acidic solutions, and in the gel. The reversible denaturations of bovine serum albumin solutions by heat, acid's, and alkali were studied and a new mechanism for heat denaturation has been proposed based on a continuous unfolding of the α‐helic

摘要:

AbstractNew techniques in laser Raman spectroscopy are used to obtain spectra of aqueous solutions of lysozylme for frequency shifts as small as 5 cm−1. In addition, Raman measurements are made on two crystalline forms of hen egg white lysozyme. The spectra obtained from the solution and from the crystal are found to be similar for frequencies above 100 cm−1. However, a low‐frequency band at 25 cm−1observed in crystalline lysozyme is not found in the solution, indicating that this band cannot be attributed to an internal molecular vi
