  1. Polypeptide
    A polymer (chain) of many amino acids linked together by peptide bonds.
  2. Primary structure
    The level of protein structure referring to the specific sequence of amino acids.
  3. Protein
    A three-dimensional biological polymer constructed from a set of 20 different monomers called amino acids.
  4. Quaternary structure
    The particular shape of a complex, aggregate protein, defined by the characteristic three-dimensional arrangement of its constituent subunits, each a polypeptide.
  5. Secondary structure
    The localized, repetitive coiling or folding of the polypeptide backbone of a protein due to hydrogen bond formation between peptide linkages.
  6. Substrate
    The reactant on which an enzyme works.
  7. Tertiary structure
    Irregular contortions of a protein molecule due to interactions of side chains involved in hydrophobic interactions, ionic bonds, hydrogen bonds, and disulfide bridges.
  8. Amphipathic molecule
    A molecule that has both a hydrophilic region and a hydrophobic region.
  9. Carbohydrate
    A sugar (monosaccharide) or one of its dimers (disaccharides) or polymers (polysaccharides).
  10. Cell membrane
    A lipid bilayer, containing proteins, that surrounds cells and keeps the cellular contents together. May have additional roles in regulating the flow of materials in and out of the cell, communicating information and carrying out specific biochemical functions.
