Macromolecules Overview

  1. 1.  Matter- Anything that has a mass and takes up space.  Ex. Air, Chair, Bear…
  2. 2.  Element- A type of matter that is only made up of ONE type of atom › All elements can be found on the periodic table of elements. › EX.  Hydrogen  Oxygen  Helium  Carbon
  3. 3.  Match the following Elements to their Symbol:1. Carbon A. H2. Hydrogen B. P3. Oxygen C. S4. Nitrogen D. O5. Sulfur E. N6. Phosphorous F. C
  4. 4.  Compound- A type of matter that is made up of TWO or MORE types of atoms.  Ex. Water (H2O), Sugar (C6H12O6), Carbon Dioxide (CO2) CH2OH C O H OH H C C OH OH H H C C H OH
  5. 5. Chemical Bonds Chemical Bond- A force thatholds molecules together Chemical Reaction- A process that changes one substance into a different one.
  6. 6.  Organic Compound- Compound found mainly in living things › These molecules help living things carry out important processes. › All contain Carbon Carbon is important to life… › Because it is able to form stable connections (BONDS) with other atoms. › Because it can form a stable bond it can create large molecules that are able to do unique things for the cells of living things.
  7. 7.  All Large Carbon Molecules fall into one of FOUR categories of Organic Molecules: › Carbohydrate › Lipid › Protein › Nucleic Acid
  8. 8.  Examples of Carbohydrates in the body: › All Sugars (glucose, fructose, maltose) › All Starches Made up of just THREE types of atoms: › Carbon › Hydrogen › Oxygen Does THREE main jobs(functions) for the cell: › Provides energy for the cells › Stores energy for the cells (quick energy) › Forms major body structures
  9. 9.  Examples of Lipids in the body: › Fats › Oils Made up of just THREE types of atoms: › Carbon › Hydrogen › Oxygen Does THREE main jobs(functions) for the cell: › Stores energy (long term energy) › Forms cell membranes › Carries messages
  10. 10.  Examples of Proteins in the body: › Antibody (helps protect us from infection) › Hormone (helps carry messages) › Enzyme (Helps speed up reactions) Made up of just FIVE types of atoms: › Carbon › Hydrogen › Oxygen › Sulfur › Nitrogen Does the majority of the work in the cell. Examples include: › Helps cells keep their shape › Makes up muscle › Speeds up chemical reactions › Carries messages and material
  11. 11.  Examples of Nucleic Acids in the body: › DNA › RNA Made up of just FIVE types of atoms: › Carbon › Hydrogen › Oxygen › Nitrogen › Phosphorous Does THREE main jobs(functions) for the cell: › Contains the instructions for how to build proteins › Passes the instructions from parents to offspring › Helps make proteins
  12. 12.  Write a summary at the bottom of your notes about what we discussed during this mini- lecture. Your summary should be 2-3 sentences long and include important vocabulary.
