Describe the four levels of protein structure. Explain the importance of the PDB in solving biological problems.

Question

Not too much detail for the levels of protein structure.

Answer 1

Four levels of protein structures are:

 

Primay; composed of 1 to 20 amino acids as peptides

 

Secondary: peptides joined together in covalent bonds forming secondary protein structure

 

Tertiary:  3 Dimensional structure of protein such as globular proteins: myglobin

 

Quaternary: Protein has multiple sub units such as hemoglobin has four sub units.

 

Protein data bank or PDB can reveal if certain pathological condition is due to defective protein, if that is the case then therapeutic effort might include correcting that defective protein.
