1. Primary Structure
    The sequence of amino acid residues.
  2. Secondary Structure
    Stable arrangements of amino acid residues giving rise to recurring structural patterns
  3. Tertiary Structure
    All the aspects of three dimensional folding of a polypeptide
  4. Quaternary Structure
    WHen a protein has two or more polypeptide subunits , their arrangement in space is referred to as quaternary structure.
  5. Polymorphic
    Having amino acid sequence variations in the human population.
  6. Edman Degradation
    This procedure labels and removes only the amino-terminal residue from a peptide, leaving all other peptide bonds intact. Is used to sequence a polypeptide up to 50 aa's long.
  7. Sequenator
    Is a machine where an Edman degradation is carried out. It mixes the reagents in the proper proportions, separates the products, identifies them and records the results.
  8. Sanger Method
    Is a procedure used to identify the N-terminal amino acid residue.
  9. Proteases
    Are Enzymes which catalyze the hydrolytic cleavage of peptide bonds.
  10. Proteome
    Entire Protein complement encoded by an organisims DNA.
