| Outline of Final Research Achievements |
Phospholipids constitute the basic framework of biological membranes and they are known to contain highly variable acyl chains in their hydrophobic tail portion. However, it is hardly known how those acyl chains distribute in the cellular membrane. In this project, we developed a method to define the nano-scale distribution of a specific kind of acyl chain by utilizing alkyne-labeled fatty acids and quick-freezing freeze-fracture electron microscopy. By performing click reaction on the freeze-fracture replica, labeling for the acyl chain was observed in cellular membranes, and moreover, it was shown to form clusteres in a limited region of the membrane.
