Protolytic properties of DL-alanyl-DL-methionine and its complexation in aqueous solutions and micellar solutions

Investigation of Interactions between Sodium Dodecyl Sulfate and L-Tryptophan Through Densimetry and Computer Modeling

“…A fundamental task of modern chemistry is determining the patterns of interaction between proteins and surfactants underlying different biochemical processes in the human organism and the biotechnology of manufacturing, e.g., foodstuffs, cosmetic products, pharmaceutical products [1][2][3][4][5][6][7][8][9]. Data on the properties of model compounds, which can be amino acids or micelles of low-molecular-weight surfactants with structural fragments available for electrostatic and hydrophobic interactions with solutes, are of vital importance when describing complex biological systems [10][11][12][13]. Analysis of the available literature data [11][12][13][14][15][16][17][18][19][20] shows that investigating the volume properties of aqueous solutions of surfactants containing amino acids upon changes in temperature and concentration remains of interest.…”

So far, there are almost no data on the stoichiometry of the molecular complexes formed between biologically active substances and surfactants and the effect of the structure of the reagents on the character of their interaction.…”
