Description	The paper presents a new investigation of a native and a hydrophobically modified hyaluronan (HMHA) C8NH-HA100 interactions with surfactants SDS, DTAB, and a dye polarity probe Coomassie Brilliant Blue (CBB), and their macromolecular properties in aqueous environment using Isothermal Titration Calorimetry (ITC) and SEC-MALLS. A novel alkylated HA derivative was prepared by the introduction of octyl chains onto -OH groups of the HA D-glucuronic acid unit via carbamate bond at a high degree of substitution preserving the HA carboxylic groups. Large and abrupt endothermic enthalpy changes ( H) during the titration of HA by DTAB evidence a strong electrostatic interaction and a formation of complex aggregates between HA and DTAB micelles. Heat effects of HA-SDS titration are moderate and reveal a lowering of the surfactant CMC in the presence of HA. The C8NH-HA100 displays binding with CBB in terms of exothermic enthalpy changes, which is ascribed to hydrophobic interactions, while such binding is not obs The paper presents a new investigation of a native and a hydrophobically modified hyaluronan (HMHA) C8NH-HA100 interactions with surfactants SDS, DTAB, and a dye polarity probe Coomassie Brilliant Blue (CBB), and their macromolecular properties in aqueous environment using Isothermal Titration Calorimetry (ITC) and SEC-MALLS.
