WebApr 12, 2024 · Cysteine (C3H7NO2S) is a polar amino acid. The polarity of an amino acid largely depends on the side chain attached to the alpha carbon. A polar, sulfur-containing thiol (-SH) functional group is present in the side chain of cysteine, so it is overall polar. The covalent bonds present in the carboxylic acid, amino, and thiol groups of cysteine ... WebC. Cysteine has a slightly polar S-H, but its polarity is so mild that cysteine is unable to properly interact with water making it hydrophobic. Cysteine is a very important amino acid when it comes to tertiary and quaternary structure.
