(a)

Summary Introduction

To explain: The advantages of storage polysaccharide for having a branched chain structure over the liner chain.

Introduction: In storage polysaccharides, the common examples of branched-chain polymers in cells are amylopectin and glycogen. Each one of them is degrading exolytically (external) by degradation of the end units of glucose.

(b)

Summary Introduction

To explain: The metabolic complications in the degradation of glycogen and the handling of this by a cell.

Introduction: In storage polysaccharides, the common examples of branched-chain polymers in cells are amylopectin and glycogen. Each one of them is degrade exolytically (external) by degradation of the end units of glucose.

(c)

Summary Introduction

To determine: The cause of endolytic as well as exolytic cleavage of glycosidic bonds by the enzymes contained by the cells which degrade amylase instead of amylopectin.

Introduction: In storage polysaccharides, the common examples of branched-chain polymers in cells are amylopectin and glycogen. Each one of them is degrade exolytically (external) by degradation of the end units of glucose.

(d)

Summary Introduction

To explain: The absence of branches in the structure of polysaccharide of cellulose.

Introduction: In storage polysaccharides, the common examples of branched-chain polymers in cells are amylopectin and glycogen. Each one of them is degrade exolytically (external) by degradation of the end units of glucose.

Sweet proteins. List the key classes of glycoproteins, their defining characteristics, and their biological functions.
For 100 words. What are the two essential requirements to effectively carry out metabolic work?
disease. As such, a frontline treatment for Type 2 diabetes is the drug metformin, which acts indirectly to inhibit gluconeogenesis in the liver. You are a research biochemist who would like to develop new drugs that act to directly inhibit gluconeogenesis. You have just gained access to a library of thousands of small molecules of unknown activity, and you would like to identify lead compounds that have specific inhibitory activity against steps in the gluconeogenesis pathway. (a) into PEP in order to screen for inhibitors of enzymes specific to gluconeogenesis. Which enzymes do you need to purify, what cofactors and allosteric effectors do they require, and which reactants do you need to add to reconstitute the reactions for the first bypass? Which intermediates and products are generated? Your first approach is to reconstitute the initial set of bypass reactions that convert pyruvate (b) vitro reconstitution? What additional steps and enzymes are required in liver cells but are…
