In the beginning of the 20th century, physicians hypothesized that the islets secrete a substance (named "insulin") that metabolises carbohydrates. The first to isolate the extract used, called insulin, was Nicolae Paulescu. In 1916, he succeeded in developing an aqueous pancreatic extract which, when injected into a diabetic dog, proved to ...
Insulin is a peptide hormone containing two chains cross-linked by disulfide bridges. Insulin (/ ˈ ɪ n. sj ʊ. l ɪ n /, [5] [6] from Latin insula, 'island') is a peptide hormone produced by beta cells of the pancreatic islets encoded in humans by the insulin (INS) gene. It is the main anabolic hormone of the body. [7]

Paul Langerhans (25 July 1847 – 20 July 1888) was a German pathologist, physiologist and biologist, credited with the discovery of the cells that secrete insulin, named after him as the islets of Langerhans.
After years of public outcry, Novo Nordisk, Eli Lilly and Sanofi announced caps or cuts to the cost of their insulin products. Patients with diabetes said it would make life easier.
