an amphipathic amino acid

Summary

The aromatic amino acids tryptophan (Trp, W) and Tyr and the non-aromatic methionine (Met, M) are sometimes called amphipathic due to their ability to have both polar and nonpolar character. 1 These residues are often found close to the interface between a protein and solvent 1 , and can be used to stabilize the structure of proteins.
