Clearly polar amino acids: Less polar amino acids, or indifferent amino acids: Polar amino acids are those with side-chains that prefer to reside in an aqueous (i.e. water) environment. For this reason, … Webb29 aug. 2006 · If exposed to water, such hydrogen bonds would be very weak because of competition from hydration of the polar CO and NH groups. However, polar amino acids such as lysine and glutamic acid have nonpolar necks that can interact with nonpolar side chains, as illustrated in Fig. 1(6, 7).
