{'peptide chain': [0, 0, 0, 1], 'corticotropin': [0, 0, 0, 1], 'hormones': [1, 0, 2, 2], 'oxytocin': [4, 0, 2, 2], 'insulin': [4, 0, 0, 0], 'cortisone': [3, 0, 1, 1]}

The correct answer is option 3, Insulin.

Insulin is a hormone that is produced by the pancreas. It plays a crucial role in regulating blood sugar levels. Insulin consists of two peptide chains, namely A chain and B chain, which are connected by disulfide bonds. These peptide chains give insulin its specific structure and function.

Option 1, Oxytocin, is a hormone that is also made up of a peptide chain. Oxytocin is produced in the hypothalamus and released by the posterior pituitary gland. It is involved in various physiological processes, such as childbirth and breastfeeding.

Option 2, Corticotropin, is not a hormone that contains a peptide chain. Corticotropin is an adrenocorticotropic hormone (ACTH) that is produced by the anterior pituitary gland. It is a polypeptide hormone composed of 39 amino acids.

Option 4, Cortisone, is a steroid hormone, not a peptide hormone. It is synthesized from cortisol in the human body and participates in various physiological processes including inflammation and immune response.

In summary, both options 1 and 3 contain peptide chains, while options 2 and 4 do not.
