Description

L-Glutamic Acid (Alpha) is a non-essential, proteinogenic amino acid that serves as a fundamental building block in biochemistry. It is a key intermediate in cellular metabolism and a crucial neurotransmitter in the central nervous system. This high-purity ingredient is essential for manufacturers in the pharmaceutical, nutraceutical, food & beverage, and biochemical research sectors seeking reliable, consistent quality for their formulations and processes.

Application

• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and as a component in parenteral nutrition and infusion solutions.
• Food & Flavor Enhancer: Serves as a precursor for monosodium glutamate (MSG) and other umami flavor compounds, widely used in savory foods, seasonings, and snacks.
• Dietary Supplements & Nutraceuticals: Incorporated into amino acid blends, sports nutrition products, and health supplements for its role in protein synthesis and metabolic functions.
• Biochemical Research & Cell Culture: A vital component of cell culture media, fermentation broths, and as a standard in analytical chemistry and life science research.
• Animal Feed Additive: Used to enhance the palatability and nutritional profile of feed for livestock and aquaculture.
• Cosmetic & Personal Care: Employed in hair and skin care formulations for its moisturizing and conditioning properties.
