It was found that introduction of fatty acids in positions next to the flexible linker was more strongly linked to antimicrobial activity. The fatty acid length altered the overall hydrophobicity, which was the driving force for both high antimicrobial and hemolytic activity. Peptides became highly hemolytic when carbon-chain length exceeded 10 (i.e., C1, overlapping with the optimum for antimicrobial activity (i.e., C8-C12). The most promising candidate (C8)5 showed antimicrobial activity corresponding to that of S3(, b
