Protein strcuture Flashcards
1
Q
what is the shape of a protein determined by
A
amino acids and their arrangement in the chain.
2
Q
Why is the shape of a protein vital
A
in determining properties of the protein and its function in living organisms.
3
Q
do proteins vary in size
A
yes, some can be very small or quite big.
4
Q
what are the 4 levels of protein structure
A
- Primary
- Secondary

- Quaternary
5
Q
What are the bonds involved in primary structure
A
peptide but only between carboxyl and amine groups
6
Q
what can changing a single amino acid do to a protein
A
alter its function
7
Q
what is the primary structure directed by
A
information carried within the DNA
8
Q
what is the secondary structure
