Amino Acids Flashcards
1
Q
Zwitterion
A
These are ions which have a permanent positive and negative charge but which are neutral overall
2
Q
Primary structure of a protein
A
This is the sequence of amino acids joined by peptide links in a chain
3
Q
Secondary structure
A
Twisting/ folding of the primary structure to form B pleated sheets and A helix by intramolecular hydrogen bonding
4
Q
Tertiary structure
A
Bending or folding of the secondary structure to give a 3D shape held together by hydrogen bonding / disulphides bridges / ionic interactions / VDW
5
Q
Enzyme
A
This is a protein which is a biological catalyst
6
Q
Active site
A
This is the site on the surface of the enzyme into which the substrate fits
7
Q
Induced fit
A
The substrate induces a change of shape of the active site of the enzyme
