Detailed explanation-1: -Disaccharides are formed by joining pairs of various monosaccharides via -or -glycosidic bonds. A hemiacetal hydroxyl group formed from the oxygen of the carbonyl group (−C=O) always participates in the formation of these bonds. In certain cases, all the carbonyl groups in the molecule are used.
Detailed explanation-2: -Disaccharides are formed by the condensation reactions of two simple sugar molecules. Condensation is the loss of water in a chemical reaction. Two OH groups, one from each sugar molecule, come together to release water and form an oxygen bridge between.
Detailed explanation-3: -Maltose is mainly produced by partial hydrolysis of starch and consists of two glucose units linked by an -1, 4-glycosidic bond (Figure 2(c)). Some nutritionally important disaccharides and disaccharide derivatives and their significance are outlined in Table 2.
Detailed explanation-4: -A dissaccharide formed by 1 1-glycosidic linkage between their monosaccharide units is Trehalose.
Detailed explanation-5: -N Glycosidic Bond An O-glycosidic bond is formed when the anomeric carbon of the sugar establishes a link with the oxygen atom in the hydroxyl group of the alcohol.
