PARASITE
An organism that lives on or in anothing living thing causing harm to its host
3 of 22
PATHOGEN
An organism that cause disease

PRIMARY STRUCTURE
The sequence of amino acids found in a protein molecule
5 of 22
SECONDARY STRUCTURE
The coiling or folding parts of a protein molecule due to the formation of hydrogen bonds formed as the protein is synthesised. The main forms of the secondary strucutre are the alpha-helix and the beta-pleated sheets
6 of 22
TERTIARY STRUCTRE
The overall 3D shape of a proetin molecule. It is the result of interactions between parts of the protein molecule such as hydrogen bonding, formation of disulfide bridges, ionic bonds and hydrophobic interactions
7 of 22
QUATERNARY STRUCTURE
Protein structure where a protein consists of more than one polypeptide chain. Haemoglobin and insulin both have quaternary structure
