The acetal or hemiacetal grouping of gentiobiose, reducing or nonreducing property of gentiobiose and the link between two monosaccharides has to be determined. Concept introduction: Reducing sugar: Sugars that contain aldehyde or a free ketone groups that are oxidized to carboxylic acids are classified as reducing sugars. So, the open chain form of sugars can reduce certain oxidizing agents (Tollens’, Fehling’s and Benedict’s) and become carboxylic acids. Anomeric position is carried by a – O H group for Hemiacetal sugars. Anomeric position is carried by an alkoxy group for acetal sugars. Hemiacetal sugars are in equilibrium with their open chain form. Acetal sugars are not in equilibrium with their open chain form. The linkage between monosaccharides in a disaccharide is referred to as a glycosidic linkage. Two β-D-glucose are connected to form Gentiobiose by the β-1,6 glycosidic linkage .

Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
