[IB Biology: Chemistry of Life]

Chemical Building Blocks of Life

Read Textbooks: 5th Ed. (pp. 37-39 & 48-51) or 6th Ed. (pp. 35-41)

Organic Molecules: Any compound containing C (except CO2 and those containing CO3).

Inorganic Molecules: Any compound not containing C (but including CO2 and those containing CO3).

Hydrocarbon: Any compound with a C-H bond.


Monomer: building blocks of larger molecules ---------- Polymers: repeating subunits (monomers) bonded together


[Condensation]: Reactions to build most large organic molecules. (One molecule of water removed from bond area as monomers are linked.)

Hydrolysis: Digestion: Large organic molecules are broken up. Molecule of water added to help remove the monomers.


Biological Macromolecules:

The organic molecules found in living organisms.

[Proteins] [Carbohydrates] [Lipids] [Nucleic Acids]
