Lacto-N-triaose（Cat No.:R068544）is a linear trisaccharide composed of galactose, N-acetylglucosamine (GlcNAc), and glucose, arranged as Gal(β1-3)GlcNAc(β1-3)Glc. It serves as a core structure in human milk oligosaccharides (HMOs) and is a fundamental building block for more complex glycans, including lacto-series glycosphingolipids. Lacto-N-triaose plays a crucial role in early development by promoting the growth of beneficial gut microbiota, modulating immune responses, and acting as a decoy receptor against pathogenic bacteria. Its structural simplicity and biological relevance make it a key molecule in glycoscience, prebiotic research, and infant nutrition studies.
