Description

L-Serine is a non-essential, proteinogenic amino acid that serves as a fundamental building block in biological systems. It is a critical intermediate in the biosynthesis of other amino acids, phospholipids, and nucleotides, making it indispensable for cellular metabolism and function. This high-purity compound is essential for manufacturers in the pharmaceutical, nutraceutical, and food & beverage industries, where it is used in parenteral nutrition, dietary supplements, and as a flavor enhancer.

Application

• Pharmaceutical Intermediates: A key chiral building block for synthesizing active pharmaceutical ingredients (APIs), including antibiotics and antiviral drugs.
• Parenteral & Enteral Nutrition: A vital component of amino acid infusion solutions and nutritional formulas for clinical and hospital use.
• Dietary Supplements & Nutraceuticals: Used in formulations for sports nutrition, cognitive health supplements, and general wellness products.
• Food & Beverage Additive: Employed as a flavor enhancer and a nutritional fortifier in various food products.
• Cell Culture Media: An essential nutrient in media for the cultivation of mammalian cells in biopharmaceutical production and research.
• Cosmetic & Personal Care: Incorporated into skincare formulations for its moisturizing and skin-conditioning properties.
• Biochemical Research: Serves as a standard and reagent in enzymatic studies, metabolic pathway analysis, and microbiological assays.
