  1. The forces at work on proteins/ glutamic acid and valine By Christian Noelker

  2. Van Der Waals forces • All atoms attract b/c of protons and electrons

  3. Electrostatic charge • Positive ions attract negative • Asp→→arg very stong ↑

  4. S-S bonds • Two cysteine amino acids will form a very strong bond

  5. Hydrogen bonds • Water molecules are like tiny magnets and stick (POLAR stick to POLAR)

  6. Hydrophobic • Literally means water fearing or hating • Hydrophobic aminio acids • Phenylalanine (phe), proline (pro), alanine (ala), valine (val), isoleucine (ile), leucine (leu), glycine (gly), tryptophan (trp) • No attraction to polar stuff so non-polar

  7. Hydrophilic • Literally mean water loving • Is polar attracts to polar stuff • Positive acids- Arg, Lys • Negative acids- Asp, Glu • Partially positive/negative- Tyr, Met,Asn, Thr, Gln, Ser, His.

  8. Glutamic acid • It is normal and hydrophilic, it has a negative charged and doesn’t cause stickiness • Hemoglobin proteins stick together because the valines stickiness (cause hydrophobic)makes them stick to the sickle shape.

  9. Valine • Is abnormal and hydrophobic, it has no charge and does cause stickiness. • Hemoglobin proteins stick together because the valines stickiness (cause hydrophobic)makes them stick to the sickle shape.
