Function of Sucrose

serves as the primary transport carbohydrate in plants, the principal product of photosynthesis, and a key energy source for humans and microorganisms; provides rapid energy by hydrolyzing into glucose and fructoseunF

Function of Lactose

facilitates calcium and mineral absorption, aids in gut microbiota development, and acts as a substrate for producing building blocks for brain-associated glycolipids

Function of Maltose

providing quick energy to organisms by breaking down starches, and it acts as a key carbon source in bacteria, a fermentation substrate, and a stabilizer in commercial products

Function of Cellobiose

serves as a major energy source for bacteria and a product of cellulase-mediated biodegradation, ultimately converted into glucose for cellular respiration
