Choose the peptide hormone from the following

Peptide hormones or protein hormones are those hormones whose motes are peptide or protein. These hormones are synthesized in endoplasmic reticulum from which they're transported to Golgi bodies and are packed to secretory vesicles for import. Some exemplifications of peptide hormones are ghrelin, calcitonin, insulin vasopressin,etc. 
therefore, from the given options insulin is the peptide hormone. It's produced in pancreas by the beta cells of Langerhans, which is named after Paul Langerhan. Pancreas acts as both exocrine and endocrine gland. Insulin was discovered byDr. Fredrick Banting and Charles Best. 
• It's a polypeptide hormone. 
• It regulates the metabolic exertion of fats, carbohydrates, and proteins. 
• It's also known as anabolic hormone. 
• It's the first hormone to be insulated, purified and synthesized. 
• It's the first hormone to be sequenced 
• It's the first hormone to be produced by DNA technology. 
• Chemical structure of insulin was given by Sanger. It contains 51 amino acids which are arranged in two polypeptide chains. 
Action of insulin increased situations of glucose in blood stimulates the cells of pancreas to increase insulin stashing in blood. The insulin circulates through the blood and takes up redundant glucose from the blood. also, when glucose position is low in the body, it inhibits the stashing of insulin.

Hence, option B is the correct answer.
