3 Proteins Sec 2.7 pg 37-39 Last day’s homework: – Read the protein summary sheet & highlight big ideas – Answer 4 qs on back side of summary

4 What is the monomer that makes up proteins? Draw an Example. The monomer is an amino acid.

5 * How to Identify an Amino Acid Central Carbon bonded to a Hydrogen AND: i) Amino Group –NH2 ii) Acidic Group –COOH iii) “R” group- remainder group differs between amino acids

6 What is the generic name of a long chain of amino acids? A long chain of amino acids is called a polypeptide.

7 How do amino acids bind together to form a dipeptide? Draw the process

8 Complete the table about the levels of organization in a protein Level of OrganizationDescription of ShapeType of Bond PrimaryLinearPeptide bonds SecondaryAlpha-helix or Pleated sheetHydrogen bonds Tertiary3-D structureBonds between R groups: Can involve Hydrogen bonds, covalent, or ionic bonds or disulfide bonds all can occur QuaternaryWhen 2 or more polypeptide chains join together Bonds between R groups also! (many different kinds)

9 Today’s Mission Build me pipe cleaner protein in partners! Follow instructions 1-6 and show me your final protein Complete the Qs on the handout as you go!
