Across
  1. 2. organic Compounds composed mainly of carbon, hydrogen, oxygen, and nitrogen
  2. 4. reaction breaking bonds
  3. 11. the carboxyl end is polar (attracted to water) or hydrophilic: "water acid"
  4. 12. makes up the cell wall of plant cells, used for support (fiber)
  5. 13. plants store glucose as
  6. 14. animals store glucose in the form of
  7. 15. many monomers linked together
  8. 17. composed of carbon, oxygen, and hydrogen
  9. 19. the monomer building blocks of proteins
  10. 20. composed of four fused carbon rings with various functional groups attached to them
  11. 23. the three most important polysaccharides
  12. 25. glucose and glucose
  13. 28. fatty acids the carbon atoms are not bonded to the maximum number of atoms; they are not full or unsaturated
  14. 29. a structural lipid made up of a long fatty acid chain joined to a long alcohol chain
  15. 31. large, nonpolar organic molecules that do not dissolve in water
  16. 32. gets their energy from plants and animals
  17. 34. two simple sugars formed by monosaccharides
  18. 35. acids very large and complex organic molecules that store important information in the cell.
  19. 36. acids unbranched carbon chains that make up most lipids
  20. 37. simple sugars, also isomers
Down
  1. 1. two amino acids covalently bonded together
  2. 3. found in fruit, sweetest monosaccharide
  3. 5. composed of three molecules of fatty acid joined to one molecule of the alcohol glycerol
  4. 6. large polymers
  5. 7. repeated single molecule unit
  6. 8. reaction making bonds
  7. 9. many sugars that are formed from 3 or more monosaccharides
  8. 10. fructose and glucose
  9. 16. adenosine diphosphate. provides energy for most cellular activities
  10. 18. makes their own energy
  11. 21. glucose and galactose
  12. 22. made by plants during photosynthesis, main souce of energy for BOTH plants and animals
  13. 24. fatty acids each carbon atom is covalently bonded to four atoms; so the carbon atoms are full
  14. 26. have two fatty acids joined to a molecule of glycerol
  15. 27. an organic molecule that acts as a catalyst - speeds up a chemical reaction
  16. 30. store ENERGY, due to large amount of carbon-hydrogen bonds
  17. 33. found in milk
  18. 35. DNA and RNA are polymers composed of monomers
