| Research Abstract |
A phospholipid is a main component of biomembranes, and spontaneously form bilayer structure in water. In this study, the effect of a phosphatidylethanolamine, a phospholipid related with a cell division, was investigated from the viewpoint of molecular shape. For this purpose, the phosphatidylethanolamine was mixed with a normal phospholipid as well as a phospholipid with short hydrocarbon chains which has an opposite molecular shape to phosphatidylethanolamine, and it was found that the membrane fusion was suppressed by the short-chain lipid. Also, the effect of short-chain phospholipid on the membrane structure was investigated, and it was found that the structural transformation caused by the short-chain phospholipid was induced by the phase separation between normal phospholipids and short-chain phospholipid.
