Hybrid Fluorinated and Hydrogenated Double-Chain Surfactants for Handling Membrane Proteins

Abstract

Two hybrid fluorinated double-chain surfactants with a diglucosylated polar head were synthesized. The apolar domain consists of a perfluorohexyl main chain and a butyl hydrogenated branch as a side chain. They were found to self-assemble into small micelles at low critical micellar concentrations, demonstrating that the short branch increases the overall hydrophobicity while keeping the length of the apolar domain short. They were both able to keep the membrane protein bacteriorhodopsin stable, one of them for at least 3 months.
