PARTIAL MOLAL VOLUMES OF SULPHONIC ACIDS IN WATER SOLUTION

Partial Molal Volume, Partial Molal Compressibility and Viscosity B-coefficient of Four Homologous -amino Acids in Aqueous Sodium Fluoride Solutions at Different Temperatures

THE SOLUBILITIES OF l-PROLINE AND l-HYDROXYPROLINE IN WATER, THE CALCULATED HEATS OF SOLUTION, AND THE PARTIAL MOLAL VOLUME OF l-HYDROXYPROLINE

The present work is a continuation of the previously reported studies on the solubilities of various amino acids in water and their thermodynamic properties (1). No precise solubility determinations on l-proline and/-hydroxyproline appear to have been carried out previously. Due to the high solubility of l-proline and l-hydroxyproline, it was not feasible to carry out solubility determinations ...

Prediction of Partial Molar Volumes of Amino Acids and Small Peptides: Counting Atoms versus Topological Indices

Experimental data of partial molar volumes of amino acids and small peptides were compiled from several publications and enabled us to perform a predicative analysis based on quantitative structure-property relationships (QSPR). Based on the simplest level of the descriptors, the new method has high accuracy and was found to be more reliable when compared to the latter QSPR method based on topo...

Partial Molar Volumes of 15-Crown-5 Ether in Mixtures of N,N-Dimethylformamide with Water

The density of 15-crown-5 ether (15C5) solutions in the mixtures of N,N-dimethylformamide (DMF) and water (H2O) was measured within the temperature range 293.15-308.15 K using an Anton Paar oscillatory U-tube densimeter. The results were used to calculate the apparent molar volumes (VΦ ) of 15C5 in the mixtures of DMF + H2O over the whole concentration range. Using the apparent molar volumes an...

Partial molecular volumes of lipids and cholesterol.

Volumetric measurements are reported for fully hydrated lipid/cholesterol bilayer mixtures using the neutral flotation method. Apparent specific volume data were obtained with the lipids DOPC, POPC and DMPC at T=30 degrees Celsius, DPPC at 50 degrees Celsius, and brain sphingomyelin (BSM) at 45 and 24 degrees Celsius for mole fractions of cholesterol x from 0 to 0.5. Unlike previous cholesterol...
