AMINO ACID PROPERTIES ALANINE TINY, ALIPHATIC, NON-POLAR ARGININE BASIC (the C= NH group takes up H+ to become C = NH 2 + ) ASPARTIC ACID SMALL, ACIDIC ASPARAGINE SMALL, POLAR CYSTEINE TINY, POLAR (polar due to the -SH group on end of side chain) GLUTAMIC ACID ACIDIC GLUTAMINE POLAR GLYCINE TINY, ALIPHATIC, NON-POLAR HISTIDINE BASIC (takes up H+ on the N that is double-bonded to a carbon on the lower part of the ring. This N becomes NH + ). ISOLEUCINE ALIPHATIC, NON-POLAR LEUCINE ALIPHATIC, NON-POLAR LYSINE BASIC (the NH 2 at the end of the side chain becomes NH 3 + ) METHIONINE SMALL, NON-POLAR (due to S embedded in the middle of the side chain instead of at the end, as it is in cysteine. PHENYLALANINE NON-POLAR, ALIPHATIC, AROMATIC PROLINE NON-POLAR, ALIPHATIC SERINE TINY, POLAR THREONINE SMALL, POLAR TRYPTOPHAN NON-POLAR, AROMATIC (unclear as to why the polarity of the N in the ring is not a factor. Perhaps because it
