Integrated Biochemistry Review and Study Questions

To assist you in reviewing Biochemistry for the Part I National Boards, review questions were prepared and are accompanied
by suggested study or thought questions in red text. Additionally, written answers - as endnotes - are provided to foster easier
review rather than new learning. To see the answer, move the mouse cursor over the endnote number (exponent) and the
endnote pops up. Greek letters, super/subscripts formatting are lost in the popup note, so consult the actual endnote as needed.
[Additional information is within brackets in grey tone, which is also lost in the popup note.].
The TOPIC headings (centered) and their SUBTOPIC headings (left margin) are also in gray scale. Topics in Building
Blocks of Life course are in blue text. Other topics taught in the previous traditional biochemistry course are in other D1
courses, these other topics are in green text. Many subtopics can not be included in a short 50 question format, so the related
study questions attempt to expand the subtopics in the questions. Not all answers (*) are reviewed or discussed in the endnote


1. Which of the following functional groups behaves as a weak acid, i.e., dissociate a proton in aqueous solution, at

physiological pH?
A. R—CH2—R'
C. R—NH3+

E. Ph—OH

Related study questions.
[1] What is physiological pH?2 What is a weak acid compared to a strong acid?3

[2] Identify each functional group above, which can dissociate at physiological pH; and why4?
[3] Why is the pKa of –COOH and –NH2 on the α-carbon of amino acids about 1-2 pH unit higher and lower, respectively5?

2. Which of the following pairs of compounds is INCORRECTLY matched with its respective type of stereoisomerism?
A. D- and L–glyceraldehyde : absolute configuration
B. α– and β-glucose : anomer pair
C. glucose and mannose : epimers
D. cis- and trans–fumarate : geometric isomers

* E. ribose and glucose : diastereomers

Related study questions.
[1] How many configurations can an asymmetric tetrahedral carbon and a chiral carbon have6? How many different

configurations do all of the asymmetric carbons (C*) contribute in a sugar?7 How many C* in aldoses8; ribose, glucose,
and mannose; in ketoses9: ribulose, xylulose, fructose?

[2] Regarding carbons C1–C5 or C1–C6, which chiral carbons in those sugars define pairs of anomers (α/β)10, epimers11 (e.g.,
glucose and mannose) , D/L-sugar families12 (e.g., D/L-glucose).

[3] How many of the asymmetric carbon atoms of these sugars rotate polarized light, i.e., are optically active?13 If a D-sugar
always give a (+) optical rotation does the corresponding mirror image L-sugar always give a (–) rotation?14 Is there any
consistent relationship between the asymmetrical tetrahedral carbons and the direction (+ or –) of optical light rotation

[4] What are meso stereoisomers versus diastereoisomer?16 Cite an example17.

3. Which thermodynamic parameter deals with randomness and disorder?

A. enthalpy
* B. entropy

C. free energy
D. activation energy
E. potential energy

Related study questions.
[1] What is the meaning of each the terms listed18?
[2] What is the significance of random disorder versus specified order in biological systems19?
