Phospholipid head function
Web1) Random movement. sometimes phospholipids acquire enough energy to just move. This depends entirely on factors like temperature, whether there's cholesterol nearby, and whether the phospholipid has saturated or unsaturated tails. 2) Proteins can either actively or passively catalyze movement of a phospholipid across the membrane. WebCholesterol and various proteins are also embedded within the membrane giving the membrane a variety of functions described below. A single phospholipid molecule has a phosphate group on one end, called the “head,” and two side-by-side chains of fatty acids that make up the lipid “tails” (Figure 3.1.1). The lipid tails of one layer face ...
