Disclosed are an amphipathic compound having a penta-saccharide hydrophilic group, a method of preparing the same, and a method of extracting, solubilizing, stabilizing, crystallizing or analyzing membrane proteins and membrane protein complexes using the same. In particular, since the compound has a high-density penta-saccharide hydrophilic group composed of five glucose units, the compound may have an excellent effect on crystallization of membrane proteins. In addition, since the hydrophilic group used in the amphipathic compound has a novel structure, the hydrophilic group may be applied to the development of various amphipathic molecules.

Provided are a newly developed tandem malonate-based amphipathic molecule, a method of preparing the same, and a method of extracting, solubilizing, stabilizing, crystallizing or analyzing a membrane protein using the same. In addition, the compound may be used to efficiently extract membrane proteins having various structures and characteristics from a cell membrane, compared to a conventional compound, to stably store the proteins in an aqueous solution for a long time, and may be used in functional and structural analysis thereof. The analysis of the structures and functions of the membrane proteins is one of the most attractive fields in current biology and chemistry, which are closely related to new drug development.
