3-1: Carbon Compounds
1. Carbon Bonding
 Organic Compounds: made primarily of carbon
atoms
 Inorganic compounds do not contain carbon atoms
(some exceptions)
1. Carbon Bonding (cont)
 Carbon atoms have unique bonding properties
 A carbon atoms has FOUR electrons in the
outer most level
 So it can form four covalent bonds with other atoms
 Carbon Video
1. Carbon Bonding (cont)
 Carbon-based molecules have three general
types of structures
a. Straight chain
b. Branched chain
c. Ring
2. Large Carbon Molecules
 Monomers: smaller, simpler molecules
 Polymers: molecule of consisting of repeating
units of monomers
 Large polymers are called
macromolecules

Left Column
2. Large Carbon Molecules (cont)
 Monomers link to form polymers through a
chemical reaction called condensation reaction
 Every time a monomer is added a water
molecule is released
2. Large Carbon Molecules (cont)
 Polymers are broken down through a process
called hydrolysis.
 Water is used to break the bond between each
monomer
3. Energy Currency
 Life processes require a constant supply
of energy
 Andenosine Triphosphate (ATP) is a
compound used to store energy in cells
 The hydrolysis of ATP is used to create
energy for the cell.
