3′-Galactosyllactose (3’GL)

3′-Galactosyllactose (3’GL)

Product Description

3′-Galactosyllactose (3’GL) is a neutral trisaccharide oligosaccharide composed of lactose extended with an additional galactose unit through a β1-3 glycosidic linkage. It belongs to the group of galactosylated milk oligosaccharides that are structurally related to human milk oligosaccharides (HMOs) and other functional glycans found in dairy products.

3’GL is widely used in glycobiology, carbohydrate chemistry, and microbiome research. It serves as a valuable molecule for studying carbohydrate–protein interactions, enzymatic pathways of glycosylation, and microbial metabolism of oligosaccharides. Because of its defined chemical structure and high purity, it is also commonly used as a reference standard in glycan analysis and analytical studies.

Researchers also utilize 3′-Galactosyllactose in prebiotic research and gut microbiota studies, as galactosylated oligosaccharides can influence beneficial bacterial growth and metabolic activity in the gastrointestinal tract.
