Molecules of
Life/Water
1. List the four major classes of biomolecules found
in the human body.
2. Draw an ester bond and demonstrate how it is formed from the condensation
of two common functional groups.
3. Describe the three subclasses of lipids and
provide representative examples of each (drawing detailed structures not required).
4. Draw a biological membrane and explain its bilayer structure in terms of the amphiphilic nature of membrane phospholipids.
5. Give examples
of common simple carbohydrates
found in the human body.
6. Describe the hydrophilic
nature of carbohydrates in terms of hydrogen bonding.
7. Draw an ionization curve to illustrate the concept, mathematically expressed in the Henderson-Hasselbach equation, that a pool of acid molecules is half-ionized when pH = pKa.
