D-Galactose, 3-O-(N-acetyl-α-neuraminosyl)-, identified by the CAS number 83563-61-5, is a glycosylated compound that features a D-galactose moiety linked to an N-acetyl-α-neuraminic acid (sialic acid) residue. This compound is characterized by its role in biological systems, particularly in cell recognition and signaling processes. The presence of the sialic acid component contributes to its negative charge at physiological pH, influencing its interactions with proteins and other biomolecules. D-Galactose itself is a monosaccharide, a simple sugar that is part of the carbohydrate family, and is known for its involvement in various metabolic pathways. The specific glycosidic linkage at the 3-position of D-galactose is significant for its biological activity and stability. This compound may be found in certain glycoproteins and glycolipids, playing a crucial role in cellular communication and immune responses. Its structural complexity and functional properties make it a subject of interest in biochemistry and glycobiology research.

<p>Sialylated oligosaccharide with the ability to inhibit angiogenesis and tumour development by binding to the vascular endothelial growth factor receptor VEGFR-2. Moreover, sialylated N-glycans in intestinal epithelium of chickens were found to carry terminal sialylgalactose, which interacts with influenza viruses during early stages of infection.</p>
