CHEM 210 BIOCHEMISTRY MODULE 5
EXAMINATION STUDY GUIDE 2026 QUESTIONS
WITH ANSWER
◉ What are the four ways to draw organic molecules? Describe them
Answer: -Chemical formulas: C4H10 (shows elemental composition)
-Condensed formulas: CH3CH2CH2CH3 (assume molecule's
structure)
-Kekule (structural) formulas: shows connectivity with single bonds
-Line-bond formulas: shows connectivity with no carbons drawn,
just lines
◉ What are functional groups? Answer: specific arrangement of
atoms that determine physical and chemical properties of a
compound
◉ What is the alcohol functional group? Answer: CH3-OH
(methanol)
carbon connected to OH group
◉ What is the ester functional group? Answer: H3C-O-CH3
◉ What is the thiol functional group? Answer: CH3-SH
, carbon connected to sulfur
◉ Describe how vinegar is an example of functional groups Answer:
Vinegar is a standard organic compound that contains acetic acid
compound which has the functional group of a carboxylic acid
(CH3CHOOH).
The collection of atoms in the COOH gives chemical activity in the
form of acid/base reactions due to the polarity of the oxygen
presence
◉ Describe how acetone is an example of functional groups Answer:
Acetone is another standard organic compound with the functional
group of a ketone (CH3COCH3)
◉ What does R refer to in functional groups Answer: *R refers to the
"rest of the molecule" which any carbon-hydrogen (alkyl) group is
attached and is used to communicate general info about a functional
group
◉ What is glucose as a biological molecule? Answer: most common
sugar on Earth with several alcohol groups
◉ what are metabolites Answer:
