Studies on Solvation Behavior of Some Amino Acids and Lysozyme in Mixed Aqueous Solutions of
The native state of protein is a resultant of delicate balance of various interactions of protein within itself and with surrounding environment. Disruption of this balance by heat, cold, pressure, pH, denaturant etc., leads to protein denaturation. In the present paper we have investigated the effect of sodium acetate, magnesium acetate calcium acetate, sodium propionate and sodium butyrate on...
متن کاملPartial molar adiabatic compressibilities and viscosities of some amino acids in aqueous glycerol solutions at 298.15 K
positive partial molar adiabatic compressibilities of transfer at infinite dilution, ∆tr o s 2 , κ , have been observed for the studied amino acids (except at lower concentration up to ≈ 0.6 mB in some cases), and their magnitude increases with increase in concentration of glycerol. B-coefficient of transfer, ∆trB, values are positive for these amino acids, which after passing through maxima ≈3...
متن کاملAcoustical Studies of Some Derivatives of 4-Amino Benzoic Acid in 1, 4-Dioxane and Dimethyl Formamide at 308.15 K
The ultrasonic velocity, density and viscosity of some Schiff bases of 4-amino benzoic acid were measured in 1,4-dioxane and dimethylformamide at 308.15 K. Various acoustical properties such as isentropic compressibility (ks), Rao’s molar sound function (Rm), the Van der Waals constant (b), molar compressibility (W), inter molecular free len...
متن کاملModeling of Refractive Indices for Binary Aqueous Solutions of Some Alkane Polyols at Constant Temperature and Pressure
In this research, a theoretical study has been undertaken on the density and also on the relationship between refractive index and density for aqueous solutions. A simple linear equation is suggested to show this relationship. Also, a semi-empirical equation has been developed for estimating the constant of this linear equation. By using our suggested equations, the refractive indices of aq...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
