Proteins

• What are the monomers of proteins?

  Amino acids
• What is formed when two amino acids are joined togther?

  Dipeptide
• What is formed when two or more amino acids are joined together?

  Polypeptide
• What are proteins made up off?

  One or more polypeptides
• What do all living things share?

  A bank of only 20 amino acids
• How are amino acids link together?

  Condensation reactions
• What are the bonds called between amino acids when formed?

  Peptide bonds
• What is the primary structure in proteins?

  Sequence of amino acids in the polypeptide chain
• What is the secondary structure in proteins?

  Not flat or straight - hydrogen bonds form between amino acid in chain - makes it automatically coil into alpha helix or beta pleated sheet
• What is the tertiary structure in proteins?

  Coiled and folded further - more bonds form - disulfide bridges also form
• What is the quaternary structure in proteins?

  Some proteins made of several different polypeptide chains - structure is the way these polypeptide bonds are held together
