1. BIOCHEMISTRY pp. 51-60

2. Only need to write word in BLACK!

3. Carbon Bonding Organic Compounds: made primarily of carbon atoms Carbon is the molecule of life

4. Carbon Bonding (cont) • A carbon atoms has 4 e- in the outer most level • So it can form four covalent bonds with other atoms • Carbon Video

5. Carbon Bonding (cont) Carbon-based molecules have three general types of structures a. Straight chain b. Branched chain c. Ring

6. Large Carbon Molecules Draw and LABEL this image on the Left Column • Monomers: smaller, simpler molecules • Polymers: molecule made up of repeating monomers • Macromolecule: Large polymers • 4 main ones found in living organisms

7. 1. NUCLEIC ACIDS • Function: Store and transfer genetic information. • Made up of C, H, O, P, N • Monomer = nucleotide • Nucleotides: 3 basic parts • Phosphate group • a sugar • nitrogen containing base

8. There are four nucleotides A, C, G, T in DNA

9. 1. NUCLEIC ACIDS • Examples: DNA and RNA

10. 2. PROTEINS • Monomer= Amino acids • Made from C, H, O, and N • Same basic structure but differ at functional (R) group • 20 amino acids KNOW THE BASIC PART OF AN AMINO ACID!

12. 2. PROTEINS • Peptide bond: holds amino acids together • Polypeptide: formed from long chains of amino acids

13. 2. Proteins (cont) • Function • Used to Make: Hair, horns, skin, muscle and enzymes

14. 2. Proteins (cont) Examples: Found in chicken, meat, tuna, and milk
