Chapter 7

Question 1

cyclized carbs can be found in two forms

Answer 1

• six membered sugar ring - pyranose

- five membered ring - furanose

Question 2

cyclization of glucose creates

Answer 2

tow asymetric stereoisomers alpha and beta

Question 3

glucose cyclization - alpha and beta

Answer 3

alpha - if hydroxyl of carbon is below the plane of the sugar
beta - if the hydroxyl of carbon is above the plane of the sugar

Question 4

the end of a chain with a free anomeric carbin is

Answer 4

reducing end of the polymer

Question 5

homopolysaccharides and herteropylsaccharides

Answer 5

• polymers contains a single type of monosaccharide

- polymers contains more than one type of monosaccharide

Question 6

D glucose is stored and examples

Answer 6

intracellularly in both plants (starch) and animals (glycogen)

Question 7

amylose

Answer 7

linear polymer of glucose residues alpha (1-4) bonds

Question 8

amylopectin

Answer 8

has alpha(1-4) linked glucose residues with alpha(1-6) every 24-30 residues

Question 9

structure of glycogen

Answer 9

-structurally identical to amylopectin with higher frequency (every 10 residues)

Question 10

greater frequency of branch points allows

Answer 10

for rapid mobilization
