The oxidized monosaccharide for the given trisaccharide with its oxidized structure has to be determined and the usage of oxidation reaction to identify the sequence of given trisaccharide has to be explained. Concept Introduction: The hemiacetal structure of a monosaccharide is equilibrium with open structure, the oxidizing agent attacks only to the open structure of a monosaccharide because of the presence of free carbonyl group in open form. On oxidation, the aldehyde group of monosaccharides gets converted to carboxylic acid .

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.

O Two of the three statements are true. All three statements are true. O Only one of the statements is true. None of the statements are true.

Raffinose is a trisaccharide and a minor constituent in sugar beets. (a) Is raffinose a reducing sugar?Explain. (b) What are the monosaccharides that compose raffinose ? (c) β - Galactosidase is an enzyme that will remove galactose residues from an oligosaccharide. What are the products of β - galactosidase treatment of raffinose ?

isomaltose is a disaccharide which can be obtained by enzymatic hydrolysis of amylopectin. Deduce the structure of isomaltose from the following data: a. The hydrolysis of 1 mole of isomaltose with acid or alpha-glucosidase yields 2 moles of D- glucose. b. Isomaltose is a reducing sugar c. Isomaltose is oxidized with bromine water to isomaltonic acid. Insomaltonic acid methylation followed by hydrolysis yielded 2,3,4,6-tetra-O-methyl-D-glucose and 2,3,4,5- tetra-O-methyl-D-gluconate acid. d. Isomaltose methylation itself followed by hydrolysis to produce 2,3,4,6-tetra-O-methyl- D-glucose and 2,3,4-tri-O-methyl-D-glucose. Describe according to the four points above
