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.

“…The trend can probably be regarded to larger hydrophobic/ non-polar character of the side chain of the former, which causes greater electrostriction at the terminal charged groups and hence increase in V 2;/ values. Similar results were found for amino acids and/or dipeptides in aqueous sodium carboxylate solutions [14][15][16], ionic liquid [18], methanoic acid [20], sodium fluoride [22], cetyltrimethylammonium bromide solutions [23], furosemide [10], and so on.…”

“…The systematic study of DB-small biomolecule interactions can provide valuable information about small biomolecules' behavior and insight into the conformational stability of proteins in antibacterial drug DB solutions. Taking these into consideration and in continuation to our work on thermodynamics studies [14][15][16][17], in this present paper we report the volumetric properties of simple a-amino acids like glycine, L-alanine, L-valine, L-leucine and three glycyl dipeptides glycylglycine, glycyl-L-valine and glycyl-L-leucine in aqueous domiphen bromide (DB) solutions at different temperatures. The temperature range in our study (293.…”
