Product Description

L-Cystine is an amino acid with important functions and various applications, which are detailed as follows:

 

Functions

 

• Protein Structure and Stability: L-Cystine contains sulfur atoms and can form disulfide bonds in proteins. These bonds play a crucial role in stabilizing the tertiary and quaternary structures of proteins, ensuring their proper folding and maintaining their biological activities. For example, in many enzymes and antibodies, disulfide bonds formed by cystine are essential for their specific conformations and functions.
• Antioxidant Defense: L-Cystine can be converted to L-cysteine, which is a precursor for the synthesis of glutathione, a powerful intracellular antioxidant. Glutathione helps protect cells from oxidative damage by neutralizing free radicals and reactive oxygen species. This antioxidant function is vital for maintaining the health of cells and tissues and preventing various diseases associated with oxidative stress, such as cardiovascular diseases and neurodegenerative disorders.
• Detoxification Process: In the body, L-cystine is involved in the detoxification of certain harmful substances. It can conjugate with heavy metals and other toxins, facilitating their excretion from the body and reducing their toxic effects. For instance, it can bind to mercury and lead, helping to remove these heavy metals from the system.
• Hair and Skin Health: Cystine is abundant in keratin, a protein that makes up hair, skin, and nails. It contributes to the strength and integrity of these structures. In hair, the disulfide bonds formed by cystine give hair its elasticity and resistance to damage. In the skin, it helps maintain the firmness and smoothness of the skin by supporting the structure of collagen and elastin fibers.

 

Applications

 

• Nutritional Supplements: L-Cystine is often used in nutritional supplements, especially for individuals with increased requirements or those with certain medical conditions. For example, athletes may take cystine supplements to support muscle recovery and repair, as it is involved in protein synthesis. Additionally, people with skin or hair problems may use cystine supplements to improve the health of their skin and hair.
• Pharmaceutical Industry: In the pharmaceutical field, L-Cystine is used in the formulation of various drugs. It may be used in the treatment of some genetic disorders related to amino acid metabolism, such as cystinuria. It is also used in certain medications for its antioxidant and detoxifying properties, helping to treat conditions associated with oxidative stress and toxin accumulation.
• Cosmetics and Personal Care Products: Due to its role in maintaining hair and skin health, L-Cystine is widely used in the cosmetics and personal care industry. It is added to shampoos, conditioners, and hair treatments to improve hair strength, reduce breakage, and enhance shine. In skin care products, it is used to moisturize the skin, improve skin elasticity, and prevent wrinkles.
• Food Industry: L-Cystine can be used as a food additive, mainly as a nutritional enhancer. It is sometimes added to protein-rich foods to improve their amino acid profile and nutritional value. In the baking industry, it can be used to modify the properties of dough, improving its elasticity and extensibility.
