Lecture 12: Organic and Biochemistry
Here we will give a very superficial outline of organic compounds and functional groups.
We will outline the main types of naturally occuring organic compounds and describe the
(volumetrically) most important biomolecules.
Finally, we will outline the redox reactions that drive the biosphere.
You should be able to:
distinguish between alkanes, alkenes and aromatic hydrocarbons
identify the important functional groups (carboxyl, aldehyde, alcohol, amine).
know the main types of biomolecules
understand how different chemical species can act as electron acceptors (be reduced) during aerobic and anaerobic respiration.
understand how reduced chemical species can be used as a source of electrons for chemolithoautotropic organisms
