a A typical 1H-NMR spectrum of high molecular weight hyaluronan in D2O at 25 °C. U = d-glucuronic acid moiety, N = N-acetyl glucosamine moiety. b Effect of increasing dipalimitoyl phosphatidyl choline on the 1H-NMR spectra of hyaluronan. (Top to bottom) increasing concentrations of dipalimitoyl phosphatidyl choline as in Fig. 3a. The absolute intensities of the resonances of the HA–PL mixtures change from run to run due to instrumental tuning differences and the number of scans, so the data in Table 2 and in Fig. 3 were calculated and plotted relative to the intensity of the D2O resonance at 4.79 ppm
