WebNov 8, 2024 · Galactose oxidase has proven itself as a very promising and interesting biocatalyst with future applications in several fields, not only in galactose biosensing but … WebLactose is a disaccharide consisting of glucose and galactose and is found naturally in milk. Many people can't digest lactose as adults, resulting in lactose intolerance (which you or your friends may be all too familiar with). Maltose, or malt sugar, is a disaccharide made up of two glucose molecules.
