Presentation Transcript

  1. Macromolecules Chapter 6-3

  2. Organic Compounds • Compounds that contain _________ are called organic. • Derived from _________________. • Macromolecules are large organic molecules. carbon living things

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

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

  7. amino acid amino acid amino acid amino acid amino acid amino acid – – – – – Building important polymers Carbohydrates = built from sugars sugar – sugar – sugar – sugar – sugar – sugar Proteins = built from amino acids Nucleic acids (DNA) = built from nucleotides nucleotide – nucleotide – nucleotide – nucleotide

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

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

  10. Macromolecules • Examples: 1. Carbohydrates 2. Lipids 3. Proteins 4. Nucleic acids (DNA and RNA)
