Proteins Flashcards
1
Q
What are proteins made of?
A
Repeated amino acids
2
Q
How many different amino acids are there?
A
20
3
Q
How are proteins formed?
A
Carboxyl group to amine group, joined by a peptide bond through a condensation reaction.
4
Q
Primary structure of proteins?
A
The linear order of amino acids joined by peptide bonds
5
Q
Secondary structure of proteins?
A
3D structured stabilised by hydrogen bonds between carboxylate and amine dipole residues.
Alpha helix and Beta pleated sheets
6
Q
Tertiary structure?
A
3D shape of entire polypeptide chain- based on interactions of R groups with different properties
7
Q
Quaternary structure?
A
Multiple polypeptide chains forming a functioning protein
8
Q
Prosthetic Groups?
A
Non-protein molecules associated with proteins. I.e haem group in haemoglobin
