Cysteine amino acid group
WebCysteine differs from serine in a single atom-- the sulfur of the thiol replaces the oxygen of the alcohol. The amino acids are, however, much more different in their physical and chemical properties than their similarity might suggest. Consider, for example, the differences between H 2 O and H 2 S. The hydrogen bonding propensity of water is ... WebMethionine, cysteine, homocysteine, and taurine are the 4 common sulfur-containing amino acids, but only the first 2 are incorporated into proteins. Sulfur belongs to the same group in the periodic table as oxygen but is much less electronegative. This difference accounts for some of the distinctive … The sulfur-containing amino acids: an overview
