1 Journal What sub atomic particle make up elements?  What are the charges? Name one compound What are 5 Properties of Water (there are 10 in total)

2 Biochemistry The Molecules for Life

3 Introduction Biochemistry is the study of the compounds that make up all organisms. There are two main types of compounds:  Inorganic compounds do not contain any carbon. Examples include acids, bases, salts, vitamins and water (H2O).  Organic compounds contain carbon. Examples include carbohydrates, proteins, lipids, and nucleic acids.

4 Four major types of organic macromolecules Carbohydrates Proteins Lipids Nucleic Acids

5 Carbohydrates Where are they found?  Bread, pasta & potatoes (starch), milk products What are they made from (building blocks)? monosaccharide  2 joined together are called disaccharide  3 or more joined together are called polysaccharide

6 Carbohydrates What do they look like?  Monosaccharide Glucose – Used By animals as food energy for ATP Fructose – Fruit sugar

7 Carbohydrates What do they look like?  Disaccharides Lactose – milk sugar Sucrose – table sugar

8 Carbohydrates What do they look like?  Polysaccharides Glycogen – Animals store any extra starches (MANY glucoses!) Cellulose – Inside a plant cell wall (MANY glucoses!)

9 Proteins Where are they found?  Hair, muscle, peanuts, meat, enzymes What are they made from (building blocks)?  Amino Acids (20) - 2 joined together are called dipeptide 3 or more joined together are called polypepide  the strong bond that holds amino acids together is called a peptide bond

10 Proteins What do they look like?  Amino Acid – Must contain –NH 2 (amino group) and –COOH (carboxyl group)

11 Proteins What do they look like?  Dipeptide - is a molecule consisting of two amino acids joined by a single peptide bond.

12 Proteins What do they look like?  Polypeptide – Chain of amino acids

13 Enzymes Function: speed up the rate of a reaction  act as biological catalyst (speeds up a rxn)  examples: lactase, maltase, sucrase, thrombin-clot blood, insulin- diabetes What do they look like?  Enzyme – protein that acts like a catalyst

14 Enzyme What do they look like?  Activation Site – Location where substrate connects to enzyme  Lock and Key Hypothesis – A specific substrate will attach to a specific enzyme

15 Naming Enzymes most enzymes end in the letters -ase  Examples: glucasemaltase sucraseamylase-in the mouth-digest

16 Lipids Where are they found?  Butter, oil, wax, lard B. What are they made from (building blocks)?  Fatty Acids

17 Lipids What do they look like?  oils: triglycerides that are liquids at room temperature

18 Lipids What do they look like?  fats: triglycerides that are solids at room temperature

19 Lipids waxes: 2 fatty acids and an alcohol group  examples: feathers, plant leaves

20 Lipids steroids: are made of rings of carbon  examples: hormones (testosterone), frog venoms, plant poisons

21 Nucleic Acid Where are they found?  cells (nucleus) and viruses What are they made from (building blocks)?  nucleotides – nucleic acid made up 5-carbon sugar, a phosphate, and a nitrogen base

22 Nucleic Acids What do they look like?  Deoxyribonucleic Acid (DNA)

23 Nucleic Acid What do the look like?  Ribonucleic Acid (RNA)
