Chemical Compounds In Cells Power Point

  1. 1. Chemical Compounds in Cells
  2. 2. Elements <ul><li>An element is any substance that cannot be broken down into simpler substances. </li></ul><ul><li>The smallest unit of an element is an atom. </li></ul><ul><li>Example of an element is carbon. </li></ul>
  3. 3. Compounds <ul><li>A compound is two or more elements that are chemically combined. </li></ul><ul><li>The smallest unit of a compound is a molecule. </li></ul><ul><li>An example of a compound is water. </li></ul>
  4. 4. Organic and Inorganic Compounds <ul><li>Inorganic compounds do not contain carbon. </li></ul><ul><li>Organic compounds contain carbon and hydrogen and usually are associated with living things. </li></ul>
  5. 5. Four groups of Organic Compounds <ul><li>Carbohydrates </li></ul><ul><li>Lipids </li></ul><ul><li>Proteins </li></ul><ul><li>Nucleic Acids </li></ul>
  6. 6. Carbohydrates <ul><li>Made of the elements carbon, hydrogen, and oxygen </li></ul><ul><li>Supply energy for cell processes, form plant structures; short-term energy storage </li></ul><ul><li>Sugars-fruits, starch-pasta, and cellulose-found in cell walls of plants </li></ul>
  7. 7. Lipids <ul><li>Made of the elements carbon, hydrogen, and oxygen </li></ul><ul><li>Store large amounts of energy long term; form boundaries around cells </li></ul><ul><li>Fats, oils, waxes, phospholipids, and cholesterol </li></ul>
  8. 8. Proteins <ul><li>Made of the elements carbon, oxygen, hydrogen, nitrogen,and sulfur </li></ul><ul><li>Regulate cell processes and build cell structures </li></ul><ul><li>Enzymes, skin, and hair </li></ul>
  9. 9. Nucleic Acids <ul><li>Made of the elements carbon, oxygen, hydrogen, nitrogen, and phosphorus </li></ul><ul><li>Carry hereditary information; used to make proteins </li></ul><ul><li>DNA and RNA </li></ul>
