  1. Macromolecules • Macromolecules are the • BASIC STUFF OF LIFE!! • Carbohydrates-Lipids- Proteins – Nucleic Acids Benchmark SC.912.L.18.1 They Begin as MONOMERS- simple form and build into their longer form POLYMERS

  2. Carbohydrates Monomer - • Used for energy , or other specific purposes depends on carb. • Structure C, H, O • EXAMPLES: Monomer- Sugar, Glucose, Fructose • Disaccharide-Sucrose • Polysaccharide-Glycogen, Starch, Cellulose Polymer-

  3. Lipids • Used for energy or cell structure •  or insulation, warmth • Structure varies

  4. Monomer: Amino Acid Proteins • Used in almost all cell function, many have very specific functions • Only one with Nitrogen • Structure: C, H, O, N and sometimes S Polymer: PROTEIN

  5. Monomer: Nucleotide Nucleic Acids • Used to build RNA and DNA (our genetic code) • Nucleic Acids participate in the process of Protein Synthesis. Polymer: Nucleic Acid – DNA

  6. Practice Questions: • 1. Fats, oils and cholesterol are all types of what? A. cell membranes C. lipids B. hormones D. fatty acids • 2. You are analyzing a compound in the laboratory. You find that it is made up of carbon, hydrogen, and oxygen in a ratio of two hydrogen atoms for each carbon atom. How will you classify the compound? A. lipid C. carbohydrate B. protein D. nucleic acid

  7. Practice Questions: • 3. A sugar, a phosphate group, and a nitrogen base form the building blocks of which organic compound? A. carbohydrates C. nucleic acids B. lipids D. proteins • 4. RNA and DNA are which type of macromolecules?  A. carbohydrate C. nucleic acid B. lipid D. protein

  8. Practice Questions: 5.The diagram below shows the general structure of an amino acid. Which type of molecule is formed from amino acids? A. lipids C. carbohydrates B. proteins D. nucleic acids
