Product Overview

N-Acetyl-L-Cysteine, Cas No.: 616-91-1,  commonly abbreviated as NAC, is a highly bioavailable acetylated derivative of L-cysteine, featuring stable chemical properties and powerful biological activity. As an essential precursor for endogenous glutathione synthesis in the human body, NAC occupies an irreplaceable core position in health nutrition and industrial application fields. It possesses excellent antioxidant and physiological regulation capabilities, making it a versatile functional amino acid raw material. With mature industrial production technology, high purity and stable batch consistency, NAC has formed a huge global market demand system covering pharmaceutical manufacturing, nutritional health products, food industry and biotechnological research, and has become one of the most popular functional amino acid additives in the international market.

Character

N-Acetyl-L-Cysteine is a white crystalline powdery substance with good water solubility and no peculiar odor. Compared with ordinary L-cysteine, the acetylation modification greatly improves its stability, bioavailability and oxidation resistance, effectively avoiding deterioration and activity loss during storage and processing. The product strictly complies with USP and CP quality specifications. It has good compatibility with various food raw materials, nutritional formulations and pharmaceutical intermediates, does not produce adverse chemical reactions, and features high safety, strong practicability and wide adaptability for industrial and nutritional applications.

Main Functions

1.Boost Endogenous Antioxidant Synthesis:  NAC acts as a critical precursor for glutathione production in the human body. Glutathione is the core antioxidant substance of cellular defense system, which can effectively scavenge free radicals, reduce oxidative stress damage to cells, delay cellular aging, and protect the stability of human tissue and organ functions.

2.Support Liver Detoxification & Hepatic Health:  It assists the liver in metabolizing harmful toxins and metabolic wastes, reduces the burden of liver metabolism, protects liver cells from oxidative damage and chemical stimulation, and maintains normal liver physiological functions and detoxification metabolism.

3.Maintain Respiratory System Health:  NAC has excellent mucolytic and respiratory protection properties, which can dilute viscous secretions in the respiratory tract, relieve respiratory discomfort, protect lung and bronchial tissues from external pollution and oxidative irritation, and support daily respiratory health maintenance.

4.Maintain Human Physiological Balance:  It participates in human amino acid metabolism and protein synthesis regulation, stabilizes internal environmental balance, improves cellular metabolic activity, enhances body antioxidant defense capability, and maintains the normal operation of human physiological functions.

5.Food Antioxidation & Quality Preservation:  In food processing, NAC can inhibit enzymatic browning and oxidative deterioration of food raw materials, delay food spoilage, maintain food color, flavor and nutritional stability, and extend the shelf life of processed food products.

Applications 

1. Pharmaceutical Industry: Used in respiratory medicines and clinical detox preparations. It works as a mucolytic agent to thin mucus and assist detoxification.

2. Dietary Supplement & Functional Food: Added into nutritional capsules and powder supplements. It serves as glutathione precursor to deliver antioxidant support, maintain liver health and support respiratory wellness.

3. Food Industry Fortification & Processing: Applied in grain and beverage processing. It inhibits oxidative browning to retain food color and nutrition, and supplements cysteine for functional food formulas.

4. Biotech & Cell Culture Medium: Used in cell and microbial culture media. It supplies amino acid nutrition and provides antioxidant protection for cell growth.
