3′-Sialyllactose (sodium salt)（Cat No.:R065305）is a naturally occurring sialylated trisaccharide composed of sialic acid (N-acetylneuraminic acid), galactose, and glucose, commonly found in human and bovine milk. It plays a key role in promoting gut health, immune development, and the growth of beneficial microbiota, particularly Bifidobacteria, in infants. The sodium salt form enhances solubility and stability in aqueous systems, making it suitable for nutritional formulations and biomedical research. 3′-Sialyllactose is also studied for its anti-adhesive properties against pathogenic bacteria, supporting its use in infant nutrition and gastrointestinal health applications.
