Concerted proton transfer from the interfacial water to a phosphate group.
<p>This is observed after about 9 ps in the <i>ab initio</i> MD simulation of DOPC-2 system. Atom color scheme is the same as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0193454#pone.0193454.g001" target="_blank">Fig 1</a>. The water wire utilized is highlighted in blue. The proton-accepting phosphate moiety is spheres. Other water and lipid molecules are shown as sticks. Note W1 to W4 correspond to O(1) to O(4) in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0193454#pone.0193454.g002" target="_blank">Fig 2</a>.</p
