The disaccharides formed by the α-1,4-glycosidic linkage of two D-mannose have to be drawn and compare the reducing property of this disaccharide with glyosidic products of problem 20.58. Concept introduction: Glycosidic linkage forms disaccharide by reaction of the – O H group on the anomeric carbon of one monosaccharide with an – O H group of a second monosaccharide, the naming of linkage is according to the number of the carbon at which the linkage begins and the carbon on the second monosaccharide at which the linkage ends. 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 an – 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.

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.
