Highlights► The intestinal microbiome is recognized as an important determinant of health. ► Galacto-oligosaccharides are non-digestible carbohydrates. ► Galacto-oligosaccharides stimulate growth and activity of gut bacteria. ► Subtle differences in structure can result in significant differences in activity. ► Less abundant oligosaccharides from bovine milk are similar to those from human milk. 相似文献
