1 BIOCHEMISTRY pp

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

3 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

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

5 Warm Up: Copy the pictures Below into your notes On warm up page write10/7/15 and Mr. E. Will stamp the warm up page Carbon-based molecules have three general types of structures a. Straight chain b. Branched chain c. Ring

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

7 1. CARBOHYDRATES Monomer= monosaccharide (simple sugar)
Ex. Glucose, and fructose Made of C, H, and O and easily recognized by ring structure but no N like in DNA!!

8 1. CARBOHYDRATES 2 monosaccharides = disaccharide Disaccharide 

9 1. CARBOHYDRATES 2 monosaccharides = disaccharide
3 or more monosaccharides = polysaccharide Ex. Starch and Cellulose Starch= many glucose monomers

10 1. Carbohydrates Function: broken down to provide quick energy for cells Example: sugars and starches (pastas, breads, candy etc)

11 KNOW THE BASIC PART OF AN AMINO ACID!
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

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

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

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

16 3. NUCLEIC ACIDS Function: Store and transfer genetic information.
Made up of C, H, O, P, N

17 3. 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 Nitrogenous base

18 There are four nucleotides A, C, G, T in DNA

19 3. NUCLEIC ACIDS Examples: DNA and RNA

20 4. Lipids Monomer: Fatty Acids Made up of C, H, O Long and non polar
Hydrophobic: does not dissolve in water

21 4. Lipids Function: Store Energy Make up cell membranes (phospholipid)
Used to make hormones (steroids) and waxes

22 4. Lipids Function: Store Energy Make up cell membranes (phospholipid) Used to make hormones (steroids) and waxes Example Foods: Fats and oils (butter, cheese, cake etc.)
