<p>the otherwise repulsive charges of the headgroups and the absence of any <a href="page.php?w=steric_hindrance">steric hindrance</a> enables strong intermolecular interactions between the acyl chains, resulting in PA-rich microdomains. Thus in vitro, physiological changes in pH, temperature, and cation concentrations have strong effects on the membrane curvature induced by PA and lysoPA. The interconversion of lysoPA, PA, and DAG - and changes in pH and cation concentration - can cause membrane bending and destabilisation, playing a direct role</p><p>
