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
