Interactions study of polypeptides-water-methylene blue

Written by sctunisie no comments

The interaction of Methylene blue (M.B) dye with three different polypeptids [Polyasparagine (PAg), Polyaspartic acid (PAsp) and polyalanine (PAl was studied by UV- spectophotometry. The results show that different types of interactions are possible depending on concentration and polypeptids natures and the formation of complex whose constants are determined. The role of water was pointed out.
