Based on structural differences and hemolytic activity, we selected peptides from Series 1 and Series 3 and studied them as two individual sets having their respective parent peptides in each set. Set 1 comprised parent peptide p1 and new peptides 5a, 7а, and 8a, while set 2 included parent peptide p3 and new peptides 13c, 15с, 16с, and 8с (Figure and Table ).
