craigslist treasure coast fl personals Phospholipid Definition. A phospholipid is a type of lipid molecule that is the main component of the cell membrane. Lipids are molecules that include fats, waxes, and some vitamins, among others. Each phospholipid is made up of two fatty acids, a phosphate group, and a glycerol molecule. When many phospholipids line up, they …Membrane phospholipids have a structural function and affect membrane permeability, as well as the activity of membrane transport systems. 37 These compounds are regulated in part by the activity of phospholipases, which release free fatty acids from phospholipids.
