CAS 616-91-1: N-Acetyl-L-cysteine

Description: N-Acetyl-L-cysteine (NAC) is a derivative of the amino acid cysteine, characterized by the addition of an acetyl group to the nitrogen atom of the cysteine side chain. It is a white to off-white crystalline powder that is soluble in water and has a slightly bitter taste. NAC is known for its antioxidant properties, primarily due to its ability to replenish intracellular levels of glutathione, a critical antioxidant in the body. It is commonly used as a mucolytic agent to help break down mucus in respiratory conditions and is also utilized in clinical settings as an antidote for acetaminophen overdose. Additionally, NAC has been studied for its potential benefits in various health conditions, including psychiatric disorders, chronic obstructive pulmonary disease (COPD), and liver health. Its safety profile is generally favorable, although side effects can include gastrointestinal disturbances. As a supplement, NAC is often marketed for its purported benefits in enhancing detoxification and supporting overall health.
