1. 1 Macromolecules Chapter 6-3

2. 2 Organic Compounds Compounds organicCompounds that contain _________ are called organic. Derived from _________________. Macromoleculesorganic moleculesMacromolecules are large organic molecules. carbon living things

3. 96% of living organisms is made of: carbon (C) oxygen (O) hydrogen (H) nitrogen (N) Elements of Life

4. 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

5. Building large molecules of life Chain together smaller molecules (monomer) –building block molecules Big molecules built from little molecules –polymers

6. One molecule = monomer Bond them together = polymers Building large organic molecules

7. 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 amino acid amino acid – amino acid – amino acid – amino acid – amino acid –

8. 8 Bonds Single Bond: one bar Double Bond: atom shares 2 electrons, two bars Triple Bond: atom shares 3 electrons, three bars.

9. 9 Macromolecules Large ____________ molecules.Large ____________ molecules. Polymers: a large molecule formed when many smaller molecules bond togetherPolymers: a large molecule formed when many smaller molecules bond together Made up of smaller “building blocks” called MONOMERS.Made up of smaller “building blocks” called MONOMERS. organic
