Description

Turanose is a naturally occurring reducing disaccharide, chemically known as 3-O-α-D-glucopyranosyl-D-fructose. This unique sugar isomer is valued for its specific biochemical interactions and role as a metabolic intermediate. It serves as a critical standard and reagent in life science research, analytical chemistry, and specialized food science applications, where precise carbohydrate structures are required.

Application

• Biochemical Research: Used as a standard reference compound and substrate in enzymatic studies, particularly for invertase and other carbohydrate-metabolizing enzymes.
• Analytical Chemistry: Serves as a high-purity chromatographic standard (HPLC, GC) for method development and calibration in sugar analysis.
• Food Science & Nutrition Research: Employed in studies investigating carbohydrate digestion, sweetness perception, and the metabolic pathways of rare sugars.
• Pharmaceutical Development: Investigated as a potential excipient or starting material for specialized drug formulations and diagnostic agents.
• Microbiology: Utilized in microbial fermentation studies and as a component in selective culture media for specific microorganisms.
