Chapter 3 Worksheet
Spring 2014
Match each macromolecule (Carbohydrates, Proteins, Lipids, Nucleic Acids) with the
appropriate description:
Hydrophobic and hydrophilic properties (amphipathic); energy source and a major component of
the cell membrane, other examples include vitamins, cholesterol, estrogen, and testosterone.
_________________________________
Comprises the genetic code with the use of a sugar-phosphate backbone joined by nitrogenous
bases
_________________________________
Hydrophilic molecules that are used as an energy source but may also decorate the outside of the
cell membrane and used in cell-cell adhesion and recognition. A ring structure is the most stable.
_________________________________
These molecules are primarily used for structural and mediator components of the cell, are
grouped by chemical properties of their R side chains.
__________________________________
Identify which chemical group each of the following R side chains belongs to:
CH2OH
_____________________________
CH2CH2CH2CH2CH3NH3+
_____________________________
CH2CH2SCH3
