Bio-Chemistry (AKA Organic Chemistry)
Inorganic Compounds: from minerals or non-living source.
Organic Compounds: contain Carbon & come from a living thing.
Carbon can combine with other elements to form millions of compounds.
Simplest Organic Compound is CH4 (Methane)

Bio-Chemistry (AKA Organic Chemistry)
VOCABULARY ALERT!
Polymer: long chains of carbon molecules.
Monomer: the building block of a polymer.
Examples: A bead necklace = PolymerIndividual Bead = Monomer
