Cysteine – a special component in the structure of proteins.

Cysteine is a conditionally essential amino acid and one of the building blocks of proteins. It stands out amongst amino acids due to its chemical structure, as it contains sulphur in a characteristic thiol group.

This distinctive feature of cysteine enables it to participate in the formation of disulphide bonds, which link individual parts of protein chains and contribute to the formation and stability of their structure.

From three amino acids to glutathione.

Cysteine also plays an important role in the formation of glutathione in the body. Glutathione is a tripeptide composed of three amino acids – cysteine, glycine and glutamic acid – and is naturally present in our cells.

This is where the link with N-acetyl-L-cysteine, or NAC, comes into play. This is an acetylated form which, once ingested, is metabolised in the body and acts as a source of cysteine.
