Chapter 22, Problem 7P
Interpretation Introduction

To calculate:

The number of reducing ends and non-reducing ends in given cases.

Introduction:

Glycogen is composed of glucose linked via alpha (1-4) linkages and branches occurring through alpha (1-6) linkages. In glycogen, the free C-1 end on glucose end of the molecule is called a reducing end and all the other ends are non-reducing ends.

  Biochemistry, Chapter 22, Problem 7P

Black line indicate the glycogen chain and red dot indicates the glucose monomers.

Therefore, regardless of the number of residues in the glycogen chain, there is only one reducing end for a glycogen chain. All other ends are non-reducing.

Drawing the Structure of a Glycopeptide (Integrates with Chapters 4and 5.) Consider the peptide DGNILSR, where N has a covalentlylinked galactose and S has a covalently linked glucose. Draw thestructure of this glycopeptide, and also draw titration curves for theglycopeptide and for the free peptide that would result from hydrolysis of the two sugar residues.
fill in the blanks The enzyme responsible for alpha 1,4-glycosidic linkage during glycogen synthesis is (             ) and alpha 1,6-glycosidic linkages are added using the (                ) enzyme.
