Protein Structure Flashcards
1
Q
what is the protein primary structure?
A
amino acid sequence
2
Q
what is the secondary protein structure?
A
- alpha helix + beta pleated sheet
- formed by HB between peptides
3
Q
…. can cause problems
A
proline
exist as trans + cis
4
Q
which AA has more conformational freedom than the others?
A
glycine
5
Q
what is the proteins tertiary structure?
A
packing of secondary structure
interactions: van der Waals, hydrophobic, electrostatic, hydrogen bonds
6
Q
what is the proteins quaternary structure?
A
multiple strands of AA
7
Q
haemoglobin
A
- made of 4 separate myoglobin strands
- each strand has heme unit used to transport oxygen
- strands held together by non-cov bonds
