Hi,<br><br>I am currently working with peptide/lipids interactions using the martini force field. I want to built a bacterial membrane, so I trying to find the <br>topology of the POPG lipid but until now without success. <br>

I have seen some works using the martini force field and POPG lipids, e.g., " The molecular mechanism monolayer PNAS 105, 10803-10808", but they don't specify the topology of POPG lipids.<br>

<br>Could anyone help me to find such topology? <br><br>Thanks a lot for your time,<br><br>Salvador<br> <br><hr>Windows Live: Make it easier for your friends to see <a href="http://www.microsoft.com/middleeast/windows/windowslive/see-it-in-action/social-network-basics.aspx?ocid=PID23461::T:WLMTAGL:ON:WL:en-xm:SI_SB_2:092009" target="_blank">what you’re up to on Facebook.</a></div>
