Description

D-Mannose Isomerase is a highly specific enzyme that catalyzes the isomerization of D-mannose to D-fructose. This biocatalyst is essential for industrial processes requiring precise sugar conversion, offering high selectivity and efficiency under mild reaction conditions. It is a critical component for manufacturers in the food, pharmaceutical, and bio-based chemical industries seeking to produce high-value sweeteners, intermediates, and specialty carbohydrates.

Application

• High-Fructose Syrup (HFS) Production: Used in enzymatic pathways for the conversion of mannose-containing feedstocks into fructose, a key sweetener.
• Pharmaceutical Intermediate Synthesis: Facilitates the production of rare sugars and glycosylated compounds used in drug development and nutraceuticals.
• Functional Food & Beverage Manufacturing: Enables the creation of prebiotic compounds like manno-oligosaccharides (MOS) and low-calorie sweeteners.
• Biocatalysis & Green Chemistry: Serves as a sustainable catalyst in biorefineries for converting biomass-derived sugars into valuable chemical building blocks.
• Diagnostic Reagent Formulation: Employed in enzymatic assay kits for the specific detection and quantification of D-mannose in clinical and research settings.
• Research & Development: Used in biochemical studies of carbohydrate metabolism, enzyme kinetics, and metabolic pathway engineering.
