The present invention relates to an amphiphilic compound having a dendronic hydrophobic group, a method for preparing the same, and a method for extraction, solubilization, stabilization, or crystallization of a membrane protein by using the same. The use of the compound according to the present invention leads to an excellent membrane protein solubilization effect and a stable storage of a membrane protein in an aqueous solution for a long time, and thus can be utilized for functional analysis and structural analysis of the membrane protein. Especially, the amphiphilic compound having a dendronic hydrophobic group showed very remarkable characteristics in the visualization of protein composites through an electronic microscope. The membrane protein structural and functional analysis is one of the fields of greatest interest in current biology and chemistry, and more than half of the new drugs that are currently being developed are targeted at membrane proteins, and thus the amphiphilic compound of the present invention can be applied to membrane protein structure studies closely related to the development of new drugs.
