1
Q
What protein structures contribute to haemoglobin?
A
-Primary structure ((The sequence of amino acid in each haemoglobin chain))
-Secondary structure ((Either B-pleated sheets or A-helices))
-Tertiary structure ((determines the shape of the oxygen binding site))
-Quaternary ((All polypeptides in the protein molecule are associated with haem groups))
