Products Description of Maltose CAS#69-79-4

Maltose is the abbreviation of maltobiose, also known as D-maltose and maltose. A disaccharide formed by connecting, condensing, and dehydrating two molecules of α-D-glucose through α-1,4 glycosidic bonds. There is also a free hemiacetal hydroxyl group in the molecule, which is a reducing sugar. Like glucose, it can make Doron's reagent and Fehling's reagent react positively. These α-1,4-glucoside bonds are connected to form a long chain, which is called amylose, with an average molecular weight of 20,000 to 200,000.

Product Application of Maltose CAS#69-79-4

Scientific research and experiments. There is an aldehyde group in the molecular structure of germose, which has reducing properties and is a reducing sugar. Therefore, it can react with silver ammonia solution to produce a silver mirror, or it can react with newly prepared alkaline copper hydroxide to form a brick-red precipitate. It can be hydrolyzed under certain conditions to produce two molecules of glucose. Used as biological culture medium, polysulfide determination agent, analytical chemistry colorimetric determination standard brown
