Description : Insulin possesses two polypeptide chains denoted A and B that are linked by disulfide bonds. Upon denaturation by reduction of the SH groups of insulin, followed by reoxidation, only 7% of the ... can these data be reconciled with the hypothesis that the amino acid sequence directs protein folding?
Last Answer : Insulin is synthesized as preproinsulin that is proteolytically processed in the β cells of the islets of Langerhans in the pancreas, to give proinsulin. After synthesis and folding, a section of the ... lacking the C peptide, lacks some of the information necessary to direct the folding process.
