WebA typical cell-surface receptor has three different domains, or protein regions: a extracellular ("outside of cell") ligand-binding domain, a hydrophobic domain extending through the membrane, and an intracellular ("inside of cell") domain, which often transmits a signal. WebAn amphipathic molecule is a molecule that has a polar region that is hydrophilic and a nonpolar region that is hydrophobic. Triglyceride is an example of an amphipathic molecule. The three fatty acids make up the nonpolar, hydrophilic end and a glycerol molecule makes up the polar, hydrophobic end.

WebThe biological molecules known as phospholipids have a hydrophilic "head" region and a nonpolar, hydrophobic "tail." These forces cause the phospholipid molecules to aggregate together so that the polar heads are oriented towards the water and the hydrophobic tails are buried inside. The effect is to spontaneously establish a membrane.

WebExplain how the presence of C=C double bonds in the fatty acids of phospholipids alters membrane properties. Double bonds in unsaturated hydrocarbon tails create kinks, and spaces among the tails. This reduces strength of van der Waals interactions and weakens the barrier to solutes. Allows some molecules to leak through.
