The general formula for disaccharides is CnH2nOn-1. Disaccharides can be classified based on the type of monosaccharides they contain. Maltose, which consists of two glucose units, has the structure α-D-glucopyranose α 1-4 glycosidic bond . It is a reducing sugar and is found in germinating grains. Isomaltose, also composed of two glucose units, has the structure α-D-glucopyranose -α 1-6 glycosidic bond . It is a reducing sugar and is produced during starch digestion. Lactose, made up of a glucose and a galactose unit, has the structure β-D-galactopyranose & β-D-glucopyranose -β 1-4 glycosidic bond . It is a reducing sugar and is found in milk and dairy products. Lactulose, a synthetic disaccharide, consists of a galactose and a fructose unit with the structure β-D-galactopyranose & β-D-Fructofuranose -β 1-4 glycosidic bond . It is not naturally occurring and is used as a laxative and in the treatment of hepatic encephalopathy. Cellobiose, composed of two glucose units, has the structure β-D-glucopyranose -β 1-4 glycosidic bond . It is a non-reducing sugar and is found in the cell walls of plants. Sucrose, commonly known as table sugar, consists of a glucose and a fructose unit with the structure α-D-glucopyranose & β-D-Fructofuranose -α1 β2 glycosidic bond . It is a non-reducing sugar and is obtained from sugarcane and sugar beets. Invert sugar is a mixture of glucose and fructose formed by hydrolyzing sucrose. It is found in honey and is used as a sweetener. Trehalose, made up of two glucose units, has the structure α-D-glucopyranose -α 1-1 glycosidic bond . It is a non-reducing sugar and is found in certain organisms like fungi and insects. In conclusion, disaccharides are important carbohydrates with various structures, properties, and sources, and they play significant roles in nutrition and various biological processes ..................................................................................... كلمات مفتاحية | key words : شرح disaccharides biochemistry disaccharides biochemistry شرح disaccharides biochemistry شرح بالعربي disaccharides شرح disaccharides disaccharides biology disaccharides classification disaccharides formation CHO chemistry disaccharides شرح carbohydrates disaccharides carbohydrate disaccharides Bio disaccharides carbohydrates chemistry disaccharides chemistry of disaccharides understanding disaccharides all about disaccharides disaccharides in Arabic .................................................................................... علامات تصنيف | hashtags : #biochemistry #medicine #بايو #شرح #طب #carbohydrate #CARBOHYDRATES #SACCHARIDES #BIOCHEMISTRY#medical_students #biochemistry #carbohydrate #sugarfree #disaccharides #sugar
