Organic Organic CompoundsCompounds
• CompoundsCompounds that contain _________ are called organicorganic.
• Derived from _________________.• MacromoleculesMacromolecules are large
organic moleculesorganic molecules.
carbon
living things
• 96% of living organisms is made of: carbon (C) oxygen (O) hydrogen (H) nitrogen (N)
Elements of Life
Molecules of Life• Put C, H, O, N together in different
ways to build living organisms• What are bodies made of?
– carbohydrates • sugars & starches
– proteins– fats (lipids)– nucleic acids
• DNA, RNA
Building large molecules of life
• Chain together smaller molecules (monomer)– building block molecules
• Big molecules built from little molecules– polymers
• One molecule = monomer
• Bond them together = polymers
Building large organic molecules
Building important polymers
sugar – sugar – sugar – sugar – sugar – sugar
nucleotide – nucleotide – nucleotide – nucleotide
Carbohydrates = built from sugars
Proteins = built from amino acids
Nucleic acids (DNA) = built from nucleotides

Bonds• Single Bond: one bar• Double Bond: atom shares 2 electrons, two bars• Triple Bond: atom shares 3 electrons, three bars.
