Bilayer internal dynamics order parameters, membrane thickness, sterols

2 Bilayer internal dynamics order parameters, membrane thickness, sterols 

Besides monitoring morphological changes on membranes, wide-line NMR can also report on internal membrane dynamics, i.e. determine the microfluidity of the bilayer core. This is where the concept of order parameter takes place. Order parameters, S, are time and space averages (denoted by angular brackets) of the quantity
