N-Acetyl-L-Cysteine for Sale

N-Acetyl-L-Cysteine

Breathing system medications with expectorant effects, whose injectable solution is used in the early treatment of liver failure. It can also be used for the preparation of compound amino acid infusions, specialized medical foods, and health supplements.

Synthesis Methods

The raw materia L-Cystine is produced through fermentation, a biotechnological method that offers several advantages over traditional production processes. Generally, L-Cystine can be synthesized through three primary methods:

1. Chemical Oxidation: This traditional method involves the oxidation of cysteine to form L-Cystine through a disulfide bond. While effective, it often requires harsh chemicals and conditions that can be less environmentally friendly.

2. Hydrolysis: In this process, proteins (usually from animal or plant sources) are broken down into amino acids, including cysteine, which is then oxidized to form L-Cystine. Although commonly used, hydrolysis can require higher energy inputs and produce variable yields and purity depending on the protein source.

3. Fermentation: The most sustainable and cost-effective method, fermentation uses microorganisms like Escherichia coli to produce L-Cystine. This biotechnological process offers several advantages:

· Eco-friendly: It eliminates the need for harsh chemicals and minimizes environmental impact.

· Cost-effective: It is more scalable and efficient, especially for large-scale production.

· High Purity: Fermentation ensures a high-purity product, meeting stringent industry standards for food, supplements, and pharmaceuticals.

Fermentation is increasingly preferred due to its environmental benefits, cost efficiency, and ability to provide high-quality, scalable production.

Functions and Usages of N-Acetyl-L-cysteine

N-Acetyl-L-cysteine (NAC) is a sulfur-containing amino acid derivative with various biological activities. It is widely used in the fields of medicine, chemistry, food, and dietary supplements. Its downstream applications mainly include the following areas:

Applications in Clinical Medicine

Detoxification Agent: NAC is commonly used to treat acetaminophen (paracetamol) poisoning. It helps detoxify and protect the liver by enhancing the synthesis of glutathione.
Respiratory Diseases: NAC, as a mucolytic agent, is used in the treatment of chronic obstructive pulmonary disease (COPD), bronchitis, asthma, and other respiratory conditions. It helps reduce the viscosity of mucus, promotes mucus clearance, and improves breathing function.
Antioxidant Protection: As a precursor to glutathione, NAC helps reduce oxidative stress in the body, making it useful in anti-aging and anti-inflammatory applications.
Adjunct Treatment for Mental Disorders: NAC is used as an adjunct in the treatment of mental disorders such as depression, bipolar disorder, and obsessive-compulsive disorder (OCD), helping to regulate glutathione levels in the brain, thus providing neuroprotective effects.

Health Supplements and Nutritional Supplements

Antioxidant: Due to its powerful antioxidant properties, NAC is commonly used as a dietary supplement to enhance immunity, alleviate oxidative damage, and delay aging.
Liver Function Improvement: NAC's antioxidant properties help protect the liver and promote detoxification, making it a common ingredient in liver-protecting products.
Relief from Post-Exercise Fatigue: NAC helps reduce oxidative stress after exercise, promoting recovery and alleviating muscle fatigue.

Cosmetics and Skincare

Anti-Aging: NAC's antioxidant properties make it a key ingredient in some skincare products, helping to reduce the damage caused by free radicals to the skin and slow down the aging process.
Skin Protection: NAC promotes skin repair, reduces damage caused by environmental stress, and helps restore skin vitality.

Food Industry

Food Additives: NAC is used as an antioxidant and preservative in the food industry, helping to prevent oxidation and spoilage of food.
Nutritional Fortifier: As a beneficial nutritional ingredient, NAC can be added to fortified foods and beverages to enhance their antioxidant capacity and health benefits.

Agriculture and Animal Husbandry

Animal Feed Additive: NAC is used as an antioxidant in animal feed, helping animals reduce oxidative stress, improve health, and promote growth.
