3′-Sialyllactose Sodium Salt (3’SL Sodium Salt)

3′-Sialyllactose Sodium Salt (3’SL Sodium Salt)

Detailed Product Description

3′-Sialyllactose Sodium Salt (3’SL Sodium Salt) is a sialylated human milk oligosaccharide (HMO) derivative consisting of lactose linked with N-acetylneuraminic acid (sialic acid) via an α2-3 glycosidic bond, present in its sodium salt form to enhance stability and solubility. This compound represents one of the most important acidic oligosaccharides found in human breast milk, playing a significant role in infant nutrition, immune defense, and microbial regulation in the gastrointestinal tract.

As a key component of human milk oligosaccharides, 3′-Sialyllactose contributes to the development of a healthy gut microbiota, supporting the growth of beneficial bacteria such as Bifidobacteria. It also functions as a decoy receptor for pathogens, preventing harmful microorganisms from attaching to intestinal epithelial cells and thereby supporting immune protection in early life.

In addition to its biological significance, 3’SL Sodium Salt is widely used in glycobiology, glycomics, and carbohydrate chemistry research. The sodium salt form provides improved chemical stability and water solubility, making it suitable for analytical studies, enzymatic synthesis research, glycan structure analysis, and pharmaceutical investigations. Researchers frequently utilize this compound to study host–microbe interactions, immune modulation, neurodevelopmental processes, and carbohydrate metabolism.

Due to its well-defined molecular structure and high purity, 3′-Sialyllactose Sodium Salt is also used as an analytical reference standard in glycan profiling and mass spectrometry studies, as well as in biotechnology and nutraceutical research involving functional oligosaccharides.
