Analysis of hydrogen bond formation between lipids and alkaloids. Time evolution of the number of hydrogen bonds (A) between alkaloids and lipid phosphate groups and (B) between alkaloids and lipid ester groups (average number per alkaloid in both cases). PLPC – gramine: blue line; PLPC – hordenine: red line; PLPG – gramine: green line; PLPG – hordenine: violet line. For each alkaloid – lipid pair, the average number of hydrogen bonds per alkaloid during the last 100 ns is displayed.
