Description

L-(+)-Arabinose is a naturally occurring pentose sugar, specifically the L-enantiomer of arabinose, known for its high purity and consistent quality. This monosaccharide is valued for its role as a key chiral building block and a non-caloric sweetener in advanced food and pharmaceutical formulations. It serves as a critical raw material for research institutions and industrial manufacturers in the nutraceutical, cosmetic, and biotechnology sectors seeking reliable, high-grade ingredients.

Application

• Nutraceutical & Functional Food Ingredient: Used as a low-glycemic, prebiotic sweetener and a component in dietary supplements.
• Pharmaceutical Intermediate: Serves as a chiral starting material for the synthesis of nucleoside analogues and other active pharmaceutical ingredients (APIs).
• Microbiology & Cell Culture: Employed in bacterial growth media and as a carbon source in fermentation processes and biotechnological research.
• Cosmetic Formulations: Acts as a humectant and skin-conditioning agent in personal care products.
• Chemical Synthesis: Utilized as a precursor for synthesizing various specialty chemicals, flavors, and aroma compounds.
• Research & Development: Essential standard and reagent in carbohydrate chemistry, enzymology, and metabolic pathway studies.
