4-Galactosyllactose is a type of galactosyl oligosaccharide that functions as a prebiotic in promoting the growth of beneficial bacteria in the gut. It acts by serving as a substrate for specific strains of probiotic bacteria, such as Bifidobacterium, which can ferment the compound to produce short-chain fatty acids. This fermentation process creates an environment in the gut that is conducive to the growth and activity of these beneficial bacteria, thereby supporting gut health. At the molecular level, 4-Galactosyllactose interacts with the enzymes and metabolic pathways of these probiotic bacteria, influencing their growth and activity. By providing a source of nutrition for these beneficial bacteria, 4-Galactosyllactose plays a role in modulating the composition of the gut microbiota, which can have implications for health and well-being.
