Document Summary
Hydrophobic region of the protein is embedded within the hydrophobic region of the phospholipid bilayer. there"s a number of different types of channels, allowing things in and out of the cell. And again, half of the membrane is protein, the other half is not just one type of phospholipid. Phospholipids vary with respect to their phosphoryl head groups and their fatty acid side chains. A variety of phosphor events can vary with the, with respect to their phosphor world had groups, as well as their fatty acid side chains are there hydrocarbon chains. Extreme example: cardiolipin is a double phospholipid joined by a third glycerol. (wedged shape) Fatty acid chains may be unsaturated (more uid) Kinky domains, do not pack as closely as straight ones. And this allows for the membrane, to increase in its uidity more uidity enhances the function of membranes at lower temperatures.
