Description

Alpha,α-D-Galactotrehalose is a specialized disaccharide derivative of trehalose, where a galactose moiety is linked to the trehalose core. This unique structure makes it a valuable biochemical tool and intermediate for research and development in life sciences. It is particularly relevant for scientists and manufacturers working on carbohydrate chemistry, glycobiology, and the development of novel diagnostic or therapeutic agents. Our supply ensures high purity and consistency for critical applications.

Application

• Biochemical Research: Used as a substrate, standard, or intermediate in enzymatic studies and metabolic pathway analysis.
• Glycobiology & Glycochemistry: Serves as a building block for the synthesis of complex oligosaccharides, glycoconjugates, and glycomimetics.
• Pharmaceutical Development: Investigated as a potential excipient or active pharmaceutical ingredient (API) intermediate due to its sugar-based properties.
• Diagnostic Reagents: Can be utilized in the formulation of calibration standards or components for diagnostic kits targeting carbohydrate-related biomarkers.
• Food Science Research: Studied for its potential functional properties, such as sweetness modification or stability enhancement in food systems.
• Cosmetic Ingredient Research: Explored for moisturizing or skin-conditioning properties in advanced cosmetic formulations.
