1. Topic: Proteins pg.19
EQ: Explain the structure & function of proteins.

2. Proteins

3. Monomers of Proteins
AMINO ACIDS are the monomers of proteins Elements present C, H, O, N, sometimes S Elements: C,H,O, N, sometimes S

4. Amino Acids are made of…
1 common group 1 side group (“R” group)

5. Polymers of Proteins
POLYPEPTIDES are the polymer of amino acids

6. Polypeptide Shapes
Chain of amino acids-primary α helix & β sheet- secondary Three dimensional- tertiary More than one polypeptide chain- quaternary

7. QUICK CHECKS What is the monomer of proteins? Amino Acids
What are the parts of an amino acid?
1 common group & 1 side group
What is the polymer of proteins?
Polypeptide
Which biomolecule has the most versatility in its shape?
Proteins

8. Functions of Proteins
Cell membranes all contain proteins
They make up enzymes for helping chemical reactions
They make up antibodies in the immune system
They makeup non-steroid hormones
They are the major structural molecules in living things for growth and repair : muscles, ligaments, tendons, bones, hair, skin, nails
THINK: Proteins= membranes, enzymes, antibodies, non-steroid hormones, structural molecules, “MEANS”

9. Examples of proteins
Animal Products (dairy and meats) Enzymes
