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.
New polyol ether compounds and a process for their preparation. The process comprises reacting a polyol, a carbonyl compound, and hydrogen in the presence of hydrogenation catalyst, to provide the polyol ether. The molar ratio of polyol to carbonyl compound in the process is greater than 5:1.

Glycerine derivatives represented by formula (1A), (2A) and (3A):
wherein R1a, R2a, R1b, R2b, R1c, and R2c are as defined in the disclosure, and process for producing glycerin derivatives, including the glycerin derivatives (1A), (2A) and (3A), are disclosed. The glycerin derivatives have satisfactory physical properties and are applicable as lubricants or polar oils and also have mutual effects with water and are applicable as emulsifying agents or moisture retaining agents. The process makes it possible to synthesize glycerin derivatives from easily and economically available aldehydes or ketones in high yields.
