Is the following molecule ketose. There is a C=O on the third carbon from the
an aldose or ketose? top.
Briefly explain.
Which carbon in erythrose On carbon number 3, which is the penultimate
would tell you if the carbon.
monosaccharide is D or L?
Give the carbon's number
in your answer.
Glucose and mannose are Galactose
epimers. Name another
epimer of glucose besides
mannose.
Is the following structure a L. The -OH group is on the left side on the
D or L carbohydrate? penultimate carbon.
Briefly explain.
Does the compound No. This compound has does not fit the formula
C7H14O8 fit the formal CnH2nOn as indicated in the module. There is one
definition of a additional oxygen in this compound.
carbohydrate? Explain.
, Which of the following is C
carbon number 3?
(Indicate by the
appropriate letter.)
Which carbon in this A
molecule is the anomeric
carbon? (Indicate by the
appropriate letter.)
Is the following a furan or furan. There are only five atoms in the ring: one
pyran ring? Briefly explain. oxygen and four carbons.
When is the alpha 1→6 The alpha 1→6 bond is found in polysaccharides when
connection typically branching occurs.
found in carbohydrates?
Is the following an alpha This is a beta 1→4 because the molecule on the left
1→4 or beta 1→4 has the oxygen in the up, or beta, position.
connection? Briefly
explain.
What are the similarities Similarities: Both of are homopolysaccharides of
and differences between glucose. They each have alpha 1 → 4 connections
amylose and between glucose. They each are part of starch.
amylopectin? Explain in at Differences: Amylopectin has branching with alpha
least three complete 1→6 linkages. Amylose does not. Amylopectin is
sentences. typically larger than amylose.
How is chitin different Chitin has glucose with derivatives attached. -NH-
from cellulose? CO-CH3 is connected to each glucose.
Where are alpha 1 → 6 They are found where glycogen and amylopectin
bonds found in branch.
carbohydrates?
In what ways are amylose They both can form alpha helices.
and a protein alike?
What is the name of the Chitin
carbohydrate found in
beetle exoskeleton?
