WitrynaIn contrast, amino acids with nonpolar side groups avoid water and aggregate to form the waterinsoluble core of proteins. 2. distinguish between nonpolar (hydrophobic) amino acids and polar (hydrophilic) amino acids according to properties Answer: WitrynaJust have a general idea of things. Obviously Tyrosine would be more polar than something that is strictly aromatic. So would Tryptophan due to it’s Nitrogen in one of the rings. Adding CH3s makes something more non-polar. So Lecuine would be more non-polar than Valine, which would be more non-polar than Alanine, etc.
