^aBold letters indicate the number and location of the palmitoylation sites in the peptide sequence.

^bPalmitoylated peptide masses are calculated from corresponding molecular compositions.

^cCross sections here are predicted from ISP values provided in Table 2.

^dDifference percentage is defined by: $\mathit{difference}(\%)=\frac{{\Omega }_{\mathit{predicted}}-{\Omega }_{\mathit{experimental}}}{{\Omega }_{\mathit{experimental}}}\ast 100\%$
