Part A
What is a main difference between tertiary (3°) and quaternary (4°) protein structure?
3º structure involves hydrogen bond interactions between the carbonyl and amino groups of the protein backbone structure, while 4°
structure involves side chain interactions between two or more polypeptides
Proteins with 3º structure can be denatured, while proteins with 4° cannot
3° structure involves side chain interactions within the polypeptide, while 4º structure involves side chain interaction between two or
more polypeptides
3º structure involves interaction between three polypeptides, while 4º involves interaction between four polypeptides
3º structure involves alpha-helices and beta-sheets, while 4º structure involves side chain interactions within the polypeptide
