Question

When 13 units of monosaccharide combine to
give 6 units of oligosaccharide, the glycoside
linkages formed are
(a) 5 (b) 7 (c) 12 (d) 10​

Answer 1

Answer:

Because sugars contain many hydroxyl groups, glycosidic bonds can join one monosaccharide to another. Oligosaccharides are built by the linkage of two or more monosaccharides by O-glycosidic bonds (Figure 11.10). In maltose, for example, two d-glucose residues are joined by a glycosidic linkage between the α-anomeric form of C-1 on one sugar and the hydroxyl oxygen atom on C-4 of the adjacent sugar. Such a linkage is called an α-1,4-glycosidic bond. The fact that monosaccharides have multiple hydroxyl groups means that various glycosidic linkages are possible. Indeed, the wide array of these linkages in concert with the wide variety of monosaccharides and their many isomeric forms makes complex carbohydrates information-rich molecules.

Answer 2

Answer:

)B

Explanation:

To find the number of glycosidic linkages                                                                             G.B = N - X                                                                                                                         where N is total number of amino acids while X is the no of chain of oligosaccharides                                                                                                                  so the answer is G.B = 13-6 =7   same is the case for peptide bond                                                                                                    HOPE THAT HELPS ........!
