A G-protein coupled receptor (GPCR) is a seven-pass transmembrane domain receptor that aids in the signaling cascade essential for various pathways in the body. Although the receptor is situated such that it is predominantly contained within the cell membrane, small portions can be found exposed to the aqueous environments on either side. One such portion is the region that allows for ligand binding on the extracellular surface. Which of the following amino acids could be found within the ext...
