Final answer:
Glucose can react with another monosaccharide in a condensation reaction to form disaccharides like sucrose, lactose, or maltose, with the release of a water molecule.
Step-by-step explanation:
Glucose, a monosaccharide, can undergo a condensation reaction to form different types of molecules. When glucose combines with another monosaccharide such as fructose, the result is a disaccharide called sucrose. During this condensation reaction, a water molecule is released. The point at which the two monosaccharides connect is known as a glycosidic bond. Specifically, sucrose is formed when the -OH (hydroxyl) group on the #1 carbon of a(d)glucose reacts with the -OH group on fructose, forming an a1,4 glycoside linkage. Other types of reactions with glucose can form polysaccharides, such as when glucose reacts with another glucose molecule to form maltose, or with galactose to form lactose.
