Description

D-(+)-Galactose is a naturally occurring monosaccharide and a vital C-4 epimer of glucose, playing a fundamental role in cellular metabolism and glycobiology. This high-purity sugar is essential for research and industrial processes where precise biochemical interactions and structural integrity are critical. It is a key raw material and intermediate for manufacturers in the pharmaceutical, biotechnology, nutraceutical, and diagnostic reagent industries, enabling the synthesis of complex carbohydrates, cell culture media, and specialized nutritional formulations.

Application

• Pharmaceutical Synthesis: Critical precursor in the production of glycan-based drugs, antiviral agents, and complex active pharmaceutical ingredients (APIs).
• Biochemical Research & Cell Culture: Essential component in defined cell culture media, microbiological assays, and as a carbon source for fermentations and metabolic studies.
• Diagnostic Reagents: Used in the formulation of enzymatic assay kits and diagnostic tests for metabolic disorders such as galactosemia.
• Nutraceuticals & Infant Formula: Serves as a building block for human milk oligosaccharides (HMOs) and specialized nutritional products.
• Glycobiology & Enzymology: Substrate for glycosyltransferases, glycosidases, and other enzymes in mechanistic studies and enzyme characterization.
• Cosmetic & Personal Care: Incorporated into advanced skincare formulations for its moisturizing and cell-communicating properties.
