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. 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.

please draw it for me and tell me where i need to modify the structure

Answer 1

Question

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.

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.

Macmillan Learning Cholesterol synthesis begins with the formation of mevalonate from acetyl CoA. This process activates mevalonate and converts it to isopentenyl pyrophosphate. Identify the atoms in mevalonate and isopentenyl pyrophosphate that will be labeled from acetyl CoA labeled with 14C in the carbonyl carbon. Place 14C atoms and C atoms to denote which carbon atoms are labeled and which are not labeled.
