What are proteins made up of?
Carbon, hydrogen, oxygen, nitrogen and sometimes sulphur.
1 of 17
What are polymers?
They are made up of amino acids.
2 of 17
What happens if the atomic R group is polar?
The amino acid will be soluble.
3 of 17
What is a primary structure?
It is the order of the sequence of the individual amino acids in the polypeptide chain.
4 of 17
What does a protein consist of?
It consists of one or more polypeptide chain that are folded into a highly specific 3D shape.
5 of 17
What are the 4 levels of structure in a protein?
1. Primary, 2. Secondary, 3. tertiary, 4. quarternary.
6 of 17
What is a alpha helix?
It is a spiral shape, which is formed because of interactions between the alpha helixes. it is found in a secondary structure.
7 of 17
What is a beta - pleated sheet?
It can co - exist with the alpha helix. the shape is maintained by hydrogen bonds. It is found between the C=O group of one amino acid.
8 of 17
What is a hydrogen bond?
A hydrogen bond is weak, but they are very strong in large groups.
9 of 17
What does delta mean?
Delta means a small amount.
10 of 17
What are the structures in a secondary structure caused by?
The hydrogen bonds between amino acids.
11 of 17
Why do hydrogen bonds because form?
They form because the peptide bonds contain polar hydrogen and oxygen atoms.
12 of 17
What is a tertiary structure?
This is the specific folding of the secondary structure. It is specific to carry out its function. It is held together by hydrogen, ionic, and sometimes disulphic bonds.
13 of 17
What bonds are in secondary structures?
Hydrogen bonds
14 of 17
What bonds are primary structures?
Peptide bonds
15 of 17
What is a disulphide bond?
This is where 2 sulphurs are bonded together to form strong bonds.
16 of 17
What are quarternary structures?
This is when proteins have more than one polypeptide chain. they are held together by ionic bonds, hydrogen bonds and disulphide bridges. you can have non - protein (these are called prosthetic) groups involved.
