Cysteine

Cysteine is a naturally occurring hydrophilic ("water loving") amino acid which has a sulfhydryl (S H) group and is found in most proteins. When it is exposed to air it oxidizes to form cystine, which is two cysteine molecules joined by a disulfide bond. One molecule of water (H₂O) is the byproduct from the creation of each molecule of cystine.

Symbol: C or Cys

Side chain type: hydrophilic

Mass: 121.16
