  1. adhesion
    the attractive force between unlike substances
  2. ATP
    an enzyme that catalyzes the synthesis of ATP from ADP and phosphate

    a monomer that is part of most lipids
  11. hydrogen bond
    a weak chemical bond between the hydrogen atom in one molecule and an negatively-charged region of another molecule

  21. polymer
    a compound consisting of repeated linked monomers
  22. polysaccharide
    a complex carb composed of 3 or more monosaccharides
  23. proteins
    an organic compound composed of one or more chains or polypeptides which in turn are formed from amino acids
  24. peptide
    a covalent bond between two amino acids
  25. phospholipid
    a complex lipid having two fatty acids joined by a molecule of glycerol
  26. lipids
    a kind of organic compound that is insoluble in water such as fats and steroids
  27. steroid
    a lipid in which the molecule is composed of four carbon rings
