aMolecular average mass (Mav) was measured by electrospray ionization mass spectrometry (ESI MS). bHydrophobicity (H) was calculated using the online program HeliQuest (http://heliquest.ipmc.cnrs.fr/cgi-bin/ComputParamsV2.py). cHydrophobicity (H) of KV was not available due to the shorter chain length than minimum chain length required for calculation.
