About protein structure, what are the correct statements? a. The alpha-helix of proteins is a type of secondary structure made periodic by disulfide bridges. b. The alpha-helix of proteins is a type of secondary structure stabilized by hydrogen bonds between NH and CO groups of the main chain. c. The quaternary structure of protein is important to understand how hemoglobin carries Fe. d. The quaternary structure of proteins characterizes the structure of an oligomeric protein. e. As they bear more negative charges, the largest sodium dodecyl sulfate (SDS)-denatured proteins will migrate over a longer distance in a polyacrylamide gel electrophoresis.
