In synovial fluid, hyaluronic acid (HA) is an essential component for the lubrication of joints, thus preventing friction. The relationship between HA and joint friction is not unambiguously established yet. In the present study, the effect of the application of HA on the frictional coefficient in t

The behaviour of hyaluronic acid (Hyal) and sulfated hyaluronic acid (HyalS) in aqueous solution was investigated in terms of protonation and complex formation by thermodynamic and spectroscopic techniques. The presence of the scarcely protonable sulfate groups in the polymer chain provided the Hyal
