L-Cystine

L-Cystine FCC is a non-essential amino acid vital for human development formed by the dimerization of two cysteines. L-Cystine is used as an antioxidant, protecting tissues against radiation and pollution. It finds application in protein synthesis. It is required for utilization of vitamin B6 and is useful in healing burns and wounds. L-Cystine FCC is found in various nutritional products, acne treatments, and creams to treat cervical injury or inflammation. Its derivatives act as ligands for neuronal nicotine receptors and have various pharmacological activities. It serves as a building block for proteins and is crucial for maintaining a healthy immune system. FCC Grade: Chemicals that are FCC grade meet standards outlined in the Food Chemicals Codex. The FCC was acquired by the USP, but still uses the Codex for food chemical standards. This applies specifically for food ingredients and includes special tests for toxicity and ensure suitability for human consumption.

L-Cystine powder, CAS No.56-89-3, formed by the oxidation of two cysteine molecules, a non-essential amino acid. It is used as a component for parenteral and enteral nutrition and the main active ingredient for medications used to treat dermatitis. Cystine along with the amino acid methionine are the amino-acids necessary for wound healing and forming of epithelial tissue. Cystine is known to stimulate the hematopoietic system and promote the formation of white and red blood cells.
