      Product Detail  


    S - Carboxymethyl - L - Cysteine is an organic compound that plays an important role in the medical and other fields.


    Basic Information


    • Chemical Name: S - Carboxymethyl - L - Cysteine, often abbreviated as Carbocisteine.
    • Molecular Formula: C₅H₉NO₄S
    • Molecular Weight: 179.19


    Structural Characteristics
    It is formed by attaching a carboxymethyl group (-CH₂COOH) to the sulfhydryl group (-SH) of L - Cysteine. This structure gives it some characteristics of cysteine, and also endows it with unique chemical properties and physiological activities due to the introduction of the carboxymethyl group.


    Physicochemical Properties


    • Appearance: Usually white crystalline powder.
    • Solubility: It is soluble in water, more soluble in alkaline solutions, and less soluble in acidic solutions.


    Physiological Functions and Applications


    • Expectorant Effect: It is a mucus regulator that mainly acts on the secretion of bronchial glands, increasing the secretion of low - viscosity salivary mucin and reducing the production of high - viscosity fucose mucin, thereby reducing the viscosity of sputum and making it easy to cough up. It is often used to treat symptoms such as thick sputum and difficult expectoration caused by chronic bronchitis, bronchial asthma and other diseases.
    • Other Effects: In some studies, it has also been found to have certain antioxidant effects, which can scavenge free radicals in the body and may have a certain adjuvant therapeutic effect on some diseases related to oxidative stress. In addition, it may also have a certain protective effect on the respiratory mucosa, which helps to maintain the normal physiological function of the respiratory tract.
