“…The study of the interactions between surfactants, both synthetic and microbial (biosurfactants), with proteins is of great interest in various biotechnology fields and industries such as food, cosmetics, pharmaceutical, biomedical, and environmental (Lee et al 2011;Otzen 2011;Tucker et al 2014;Malik 2015). In the biomedical industry, protein-surfactant systems are used for the production of hydrogels (Afinjuomo et al 2019;Castelli et al 2008).…”

Macromolecules are essential cellular components in biological systems responsible for performing a large number of functions that are necessary for growth and perseverance of living organisms. Proteins, lipids and carbohydrates are three major classes of biological macromolecules. To predict the structure, function, and behaviour of any cluster of macromolecules, it is necessary to understand the interaction between them and other components through basic principles of chemistry and physics. An important number of macromolecules are present in mixtures with surfactants, where a combination of hydrophobic and electrostatic interactions is responsible for the specific properties of any solution. It has been demonstrated that surfactants can help the formation of helices in some proteins thereby promoting protein structure formation. On the other hand, there is extensive research towards the use of surfactants to solubilize drugs and pharmaceuticals; therefore, it is evident that the interaction between surfactants with macromolecules is important for many applications which includes environmental processes and the pharmaceutical industry. In this review, we describe the properties of different types of surfactants that are relevant for their physicochemical interactions with biological macromolecules, from macromolecules–surfactant complexes to hydrophobic and electrostatic interactions.

“…The main physical parameters that have an effect on the surfactant-protein interactions are: (a) the surfactant concentration; (b) the chemical nature of surfactant (ionic or non-ionic surfactants); and (c) the secondary structure of the protein (a-helix and bsheets) (Díaz et al 2003;Malik 2015).…”

“…As shown in Table 3, it is found that TH3 has signicant advantages in shortening the induction time, which may be the coordination of multiple unit promoters aer compounding. 43 To further understand the effects of additives on the characteristics of hydrate formation, subsequent work should be conducted with other experimental conditions.…”

“…[29][30][31][32] For the rational design of such tailor-made complexes, deeper insight into the major factors governing the of the interaction between amino acids (AAs) and surfactants is needed. Extensive knowledge has been gathered in the field of the binding of conventional surfactants to AAs, [33][34][35][36][37][38][39][40][41][42][43] but the effect of AAs on the self-assembly of 1-alkyl-3-methylimidazolium type of amphiphiles has not been studied in detail. In this work, we study how the presence of L-alanine (L-Ala), L-phenylalanine (L-Phe), and L-tryptophan (L-Trp) AAs modifies the micellization properties of 1-tetradecyl-3methylimidazolium bromide [C 14 mim][Br] in aqueous solution.…”

The effect of 3 amino acids on the self‐assembly properties of the surface‐active ionic liquid: 1‐tetradecyl‐3‐methyl imidazolium bromide, [C14mim][Br], was studied in neutral and basic aqueous solution. The critical micelle concentrations were determined by different techniques, and the thermodynamic parameters of micellization (ΔG0mic, ΔH0mic, and ΔS0mic) were measured by isothermal titration calorimetry. The critical micelle concentration values decrease in the presence of all the amino acids used in this study. The most substantial effect was observed in the presence of L‐tryptophan at pH 12, due to the electrostatic and π‐π interactions with the imidazolium headgroup of the surfactant. Always entropy‐driven micellization occurred. Both the enthalpy and entropy changes upon association to micelles increased when the pH was enhanced from 7 to 12. 1H NMR measurements demonstrated that among the used amino acids, L‐tryptophan interacts most strongly with the headgroup of the surfactant cation. The knowledge on the surfactant‐amino acid interactions significantly contributes to the deeper understanding of the effect of surfactants on the properties of peptides.
