Galacto-oligosaccharides (GOS) are a class of oligosaccharides that consist of galactose, galactose derivatives, and glucose. They are found in the human diet as a result of lactose breakdown by gut bacteria. GOS can bind to glycoconjugates in the human body, such as glycoproteins and glycolipids, and have been shown to be effective in preventing the growth of pathogens. Galacto-oligosaccharides are also synthetically produced, using a chromatographic method that separates them into individual sugars, where they can be used for research or diagnostic purposes. The biosynthesis of GOS is also known; it is an enzyme-catalyzed reaction involving calcium ions. This process is regulated by Ca2+ signaling, which leads to an increase in the production of GOS when there is a need for more immune cells or white blood cells.
