The cell membrane is sometimes also referred to as the plasma membrane. Cell membranes are based on a framework of fat-based molecules called phospholipids, which physically prevent water-loving, or hydrophilic, substances from entering or escaping the cell. These membranes are also studded with ...
In aqueous solutions, amphipathic molecules spontaneously assemble into micelles. A micelle has lower free energy than free-floating amphipaths. The polar portion of the amphipath (the hydrophilic part) forms the outer surface of the micelle and is exposed to water. The lipophilic portion of the ...

is oriented so that its polar (hydrophilic) head faces the water, while its hydrophobic hydrocarbon tail extends away from the water layer. No matter what shape a bubble has initially, it will try to become a sphere. The sphere is the shape that minimizes the surface area of the ...
Glycan separation prior to MS analysis, is achieved using LC coupled with MS for the characterization of the entire glycome. Hydrophilic interaction chromatography (HILIC)-LC, reverse phase (RP)-LC and porous graphitized carbon (PGC)-LC have been successfully used. Lubman et al., detected ...
