Function of phospholipids
By: Dr. Bryan Katz
Phospholipids can be classified according to several schemes; however, I find it useful to think of them in terms of structural and functional categories. Structural phospholipids comprise the majority of lipid bilayers found in eukaryotic cell membranes and organelles as well as internal membrane systems...
