3′-Sialyl-N-acetyllactosamine

Description:
3′-Sialyl-N-acetyllactosamine, also known as 3′-sialyllactosamine, is a complex carbohydrate that belongs to the family of sialylated glycans. It is characterized by the presence of a sialic acid residue linked to a lactosamine structure, which consists of a galactose and a glucose unit. This compound plays a significant role in biological processes, particularly in cell-cell interactions, signaling, and immune responses. The sialic acid moiety contributes to the negative charge and hydrophilicity of the molecule, influencing its solubility and interaction with proteins, such as lectins and receptors. 3′-Sialyl-N-acetyllactosamine is often found in glycoproteins and glycolipids on cell surfaces, where it can affect cellular recognition and adhesion. Its presence is crucial in various physiological and pathological processes, including viral infections and tumor progression. The compound is of interest in biochemistry and glycobiology for its potential applications in therapeutics and diagnostics.
