Presentation Transcript

  1. Proteins

  2. Examples Enzymes (amylase) Hemoglobin Insulin Keratin

  3. Monomers = Amino Acids (aa) • Structure: • amino group • carboxyl group (acid) • R group (side chain) - determines the aa (20 essential to life)

  4. Polymer = Protein (Polypeptide)

  5. Protein structure is based on the sequence of amino acids.

  6. Functions • Transport - hemoglobin • Muscle Movement - actin and myosin • Chromosome movement - spindle fibers • Support – skin, bone • Defense – antibodies • Structural – hair, nails • Hormones – testosterone, adrenalin • Enzymes

  7. Hydrolysis • Adding H20 to break a covalent bond • Splits polymers into monomers

  8. Dehydration Synthesis • Removing H20 to form a covalent bond • Builds polymers from monomers

  9. Formation of a Peptide bond • What type of reaction is this?

  10. Protein Folding

  11. Enzyme Activity • Enzyme Structure • Hydrolysis of Sucrose
