3-O-β-D-Galactopyranosyl-D-galactose（Cat No.:R029331), also known as lacto-N-biose, is a disaccharide composed of two galactose molecules linked by a β-glycosidic bond. It is found in human milk and plays a significant role in promoting the growth of beneficial gut bacteria, particularly Bifidobacteria, contributing to a healthy infant gut microbiome. This compound is of interest in nutritional science and prebiotic research for its potential to enhance digestive health and immune function. Its application extends to the development of functional foods and infant formula, aiming to replicate the benefits of human milk oligosaccharides.
