  14. 25. Fats with no carbon double bonds, solid
  15. 26. used in membranes and for energy
Down
  1. 1. link this structure to biological function (shape -> specificity)
  2. 2. "animal starch"; short-term storage of energy, made of glucose
  3. 3. made up of glycerol and three fatty acid chains; main storage of body fat
  4. 5. primary structure of cell membranes; amphipathic (hydrophilic and hydrophobic)
  5. 6. polar substance, often called the "universal solvent", with a high specific heat
  6. 7. synthesis that joins monomers, release H2O
  7. 8. catalysts, lower activation energy, not consumed in reaction
  8. 12. used for energy and structure
  9. 16. Groups like -OH (alcohol), -COOH (organic acid). -NH2, -PO4, -CH3
  10. 18. acids (less than 7), base (more than 7)
  11. 20. primary energy storage in plants; made of glucose
  12. 22. loss of 3D shape, often caused by extreme pH
  13. 24. blocks active site
