Which statement best explains how hydrophobic and hydrophilic amino acid residues influence protein folding in an aqueous environment?Single choice

A

Hydrophilic residues are usually buried in the protein core, while hydrophobic residues are usually exposed to water

B

Hydrophilic residues are the main determinants of protein folding, whereas hydrophobic residues play only a minor structural role

C

Hydrophobic residues are usually buried in the protein core, while hydrophilic residues are usually exposed to water

D

Hydrophilic residues always form covalent bonds with water, whereas hydrophobic residues cannot participate in any intermolecular interactions

E

Hydrophobic and hydrophilic residues are distributed randomly because folding is determined only by peptide bond formation

 Gene expression is considered “complete” when:

Protein disulfide isomerase (PDI) is a protein folding enzyme that catalyzes disulfide–sulfhydryl exchange reactions. Ribonuclease is an enzyme with two β‑sheets, three α‑helices, and four disulfide bridges critical to the stability of its structure. PDI rapidly converts inactive, scrambled ribonuclease to enzymatically active ribonuclease. This process is driven by the decrease in free energy as the scrambled conformations are converted into the stable, active conformation of the enzyme. In contrast, PDI rapidly inactivates insulin, a protein that forms an hexamer of alpha and beta subunits. What does PDI's effect on insulin imply about the structure of insulin?
