(a) Comparison of the I(2H) (solid symbols, right axis) and K(2H) (shaded symbols, left axis) values for 5D-L9K6C-NO (LKC-NO) and melittin-NO (Mel-NO) in DPPC-d13/PG with those of 5DSA, 7DSA, and 16DSA in DPPC-d13/PG LUVs with 5D-L9K6C (left) and melittin (right). (b) Comparison of the I(2H) values for LKC-NO and Mel-NO in DPPC/PG/D2O (squares) with those of 5DSA, 7DSA, and 16DSA in DPPC/PG/D2O with 5D-L9K6C (left) and melittin (right). The circles (connected by a line) correspond to the same in a PC/PG/D2O system, including also melittin-NO and 5D-L9K6C-NO in PE/PG/D2O.
