Volumetric Properties of Glycine, l-Alanine, and l-Serine in Formamide–Water Mixtures at 298.15 K

The density of glycine, L-alanine, and L-serine in formamide− water mixtures was measured at 298.15 K and used to calculate the apparent molar volume V ϕ and limiting partial molar volume V ϕ °of the amino acids. Transfer partial molar volume Δ tr V ϕ °from water to formamide−water mixtures and the volumetric interaction coefficients were also obtained to interpret the solute−solvent interaction. Values of Δ tr V ϕ °of the three amino acids were all positive and increased with increasing formamide concentration in the mixtures, in the order of L-alanine < glycine < L-serine, which was consistent with the cosphere overlap model. The interaction of formamide molecules decreased its structural-breaking effect and consequent interaction with amino acids, leading to negative triplet interaction coefficients.

This study aims to understand how glycyl dipeptide affected the compressibility, volumetric behavior and viscometric behavior of the cationic surfactants CTAB (Cetyltrimethylammonium bromide) and DTAB (dodecyltrimethylammonium bromide). Information on solute–solute, solute–solvent, and solvent–solvent interactions has been inferred using the quantification of density (), speed of sound (u) and viscosity in aqueous media containing glycyl dipeptide in the temperature range 293.15–313.15 K at an interval of 5 K. The data from the aforementioned research have been used to enumerate numerous volumetric and compressibility metrics that aid in the collection of information about the interactional behavior of the system under consideration. The study suggests that CTAB interacts strongly compared to DTAB with dipeptide, and it also significantly dehydrates glycyl dipeptide. The difference in water–water interactions caused by the loss of hydrophobic hydration of the surfactant molecules upon the addition of cationic surfactants may be the cause of the variation in determined parameters with surfactant concentration. Consideration of the structural rearrangement of molecules that may occur in the system has been used to explain the results of viscosity and computed factors related to viscosity. The patterns of competitive intermolecular interactions in the ternary (dipeptide + water + surfactant) system have been used to analyze the trends of all the parameters. The study may be helpful to understand the stability and structural changes in protein–surfactant systems mediated through various interactions that may be present in the system.
