Novicidin is a novel antimicrobial peptide that is an improvement on certain preexisting antimicrobial peptides (such as melittin) in that it more effectively targets bacteria and causes less hemolysis. Through various experiments, the researchers propose that an explanation for this difference is the relative proportion of hydrophobic to hydrophilic elements in novicidin composition, as well as the locations of these elements, which lowers the free energy of novicidin interaction and embedding in negative (bacterial) membranes in comparison to zwitterionic (human) membranes.
