Define primary structure |
Number and sequence of amino acids |
|
|
|
What are the bonds of the primary structure? |
Peptide bonds (Formed by dehydration synthesis or condensation) (Peptide bonds = covalent bonds) |
|
|
|
Name the types of secondary protein structures |
1. Alpha helix 2. Beta pleated sheets 3. Beta bonds (loops) (1. And 3. Have to line or glycine naturally bending) |
|
|
|
What are the bonds of an alpha helix? |
Hydrogen bonds and van der waals forces |
|
|
|
What are the bonds of beta pleated sheets? |
Hydrogen bonds (May be parallel or anti parallel) |
|
|
|
Define tertiary structure |
-folded for function -enzymes (-ase) are folded -hemoglobin is folded |
|
|
|
What are the types of bonds in the tertiary structure? |
-disulfide bonds -hydrogen bonds -salt bridges (have charge) -hydrophobic interactions |
