Cysteine derivative

Cysteine derivatives are chemical compounds that stem from the amino acid cysteine. Cysteine is a crucial amino acid involved in protein synthesis and the formation of disulfide bonds, which help stabilize protein structures. Its derivatives have various applications, including their use as antioxidants in dietary supplements and cosmetics. N-acetylcysteine (NAC), a well-known derivative, is used as a medication to treat conditions like acetaminophen overdose and chronic obstructive pulmonary disease (COPD).
