1. Biomolecules Do Now: Make your week 1 observations of your Winogradsky columns. The back of the procedure sheet is probably a wise place to do this.

2. Biomolecules Biomolecules, aka macromolecules are the organic (carbon containing) chemicals living cells are made up of. Most macromolecules are polymers: long chains of repeating subunits. There are 4 main classes of macromolecules, which we will take a look at in a little more depth.

3. Nucleic Acids: Information Carriers Nucleic acids are chemicals that store genetic information. They are polymers made of many nucleotides. DNA and RNA are the most common examples

4. Nucleotides: Building Blocks of Nucleic Acids Nucleotides are the monomers nucleic acids are made of DNA has 2 nucleotide chains, RNA has only 1 (single stranded) A, T, G, C, U

5. Carbohydrates: Sugars and Fiber Carbohydrates come in many sizes and shapes. 2 main functions: store energy and form cell walls (plants and prokaryotes)

6. Simple vs. Complex Carbs Complex carbs (like starch) are polysaccharide molecules made up of many monosaccharide subunits. Simple carbs (sugars) are mono- or disaccharides made of few monosaccharide subunits

7. Monosaccharides: Building blocks of Carbohydrates cellulose

8. Proteins: Git ‘er Done Proteins have a HUGE number of functions in cells. They are the molecules responsible for carrying out the chemical reactions that make life possible

9. Amino Acids: Monomers of Protein Polypeptide is another word for protein. Peptide is another word for amino acid. Proteins are usually made of thousands of amino acids joined together in a specific order.

10. Proteins are Way Cool

11. GFP

15. Lipids: Fats, oils, and waxes Lipids are NOT polymers made of monomers. Lipids are a large group of many different types of compounds. What they have in common is they are HYDROPHOBIC

16. Lipid Functions MOST IMPORTANT: A lipid bilayer surrounds every living cell

17. Hormones and steroids help regulate processes in animals. Can have powerful effects. Lipid Functions

18. Energy Storage … long term Lipid Functions
