Cysteine is a non-essential amino acid and is one of the few that contains sulphur. Cysteine strengthens the protective lining of the stomach and intestines and plays an important role in immune function.
Like all other amino acids cysteine's most important function is to contribute to the structure of proteins. One such protein that cysteine helps to form the structure of is keratin, which is found in hair, skin and nails. It also acts as a detoxifier and plays a role in energy metabolism and fatty acid synthesis.
