Presentation Transcript

  1. Amino Acids and Proteins • Amino Acids

  2. L-isoleucine

  3. zwitterion

  4. Synthesis of Amino Acids • Strecker Synthesis

  5. Gabriel Synthesis

  6. Biosynthesis

  7. Transamination

  8. Polypeptides and Proteins

  9. Carboxypeptidase

  10. Trypsin, chymotrypsin

  11. BrCN

  12. Complete hydrolysis of a polypeptide gives: Gly, 3 Leu, 2 Tyr, 2 Phe, 2 Lys, Ser, 2 Met, Ala, Val, Ile, Arg, Pro • Cyanogen bromide generates a tripeptide, a heptapeptide, and an octapeptide; each is sequenced: • Leu-Pro-Phe • Gly-Leu-Trr-Phe-Lys-Ser-Met • Ala-Leu-Tyr-Lys-Val-Ile-Arg-Met

  13. Partial hydrolysis with trypsin gives a tripeptide, a tetrapeptide, a pentapeptide, and a hexapeptide; each is sequenced: • Val-Ile-Arg • Met-Leu-Pro-Phe • Gly-Leu-Tyr-Phe-Lys • Ser-Met-Ala-Leu-Tyr-Lys • What is the sequence for the original polypeptide?

  14. Polypeptide and Protein Synthesis

  18. Secondary Structures of Polypeptides and Proteins

  19. Pleated Sheet

  20. -Helix

  21. Tertiary Structures of Polypeptides and Proteins

  22. Enzymes • Carboxypeptidase A
