The forces at work on proteins glutamic acid and valine

The forces at work on proteins/ glutamic acid and valine

By Christian Noelker


Van der w aals forces

Van Der Waals forces

  • All atoms attract b/c of protons and electrons


Electrostatic charge

Electrostatic charge

  • Positive ions attract negative

  • Asp→→arg

    very stong ↑


S s bonds

S-S bonds

  • Two cysteine amino acids will form a very strong bond


Hydrogen bonds

Hydrogen bonds

  • Water molecules are like tiny magnets and stick (POLAR stick to POLAR)


Hydrophobic

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


Hydrophilic

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.


Glutamic acid

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.


Valine

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.
