L-Arginine (R&D Naturals)

L_ArginineL-Arginine

Description
White, powdered, conditionally essential amino acid.
Origin
Precursors and biosynthesis made in UK.
Biosynthesis & Extraction
Biosynthesized from the precursor L-Glutamic acid through ornithine and citrulline. Corynebacterium (Brevibacterium) is utilized as a strain for its strong biosynthetic pathway to L-Arginine.
Quality Control
The fermentation is controlled by regulating pH near the neutral point. Advanced purification methods are utilized in order to obtain highly pure L-Arginine from the fermentation broth. Bacterial cells and proteins are removed by means of a membrane or centrifugation, and impurities are removed by means of an ion-exchange resin or activated carbon. Extremely purified L-Arginine crystals is obtained through concentration at the end of the process.
