Gender Norms & Racial Bias in the Study of the Modern "Insulin"
Insulin is a peptide hormone produced by beta cells in the pancreas, and by Brockmann body in some teleost fish. It regulates the metabolism of carbohydrates and fats by promoting the absorption of glucose from the blood to skeletal muscles and fat tissue and by causing fat to be stored rather than used for energy. Insulin also inhibits the production of glucose by the liver.
Except in the presence of the metabolic disorder, diabetes mellitus and metabolic syndrome, insulin is provided within the body in a constant proportion to remove excess glucose from the blood, which otherwise would be toxic. When blood glucose levels fall below a certain level, the body begins to use stored glucose as an energy source through glycogenolysis, which breaks down the glycogen stored in the liver and muscles into glucose, which can then be utilized as an energy source. As a central metabolic control mechanism, its status is also used as a control signal to other body systems. In addition, it has several other anabolic effects throughout the body.
Diabetes mellitus can be a result when the control of insulin levels fails. Consequently, insulin is used medically to treat some forms of diabetes mellitus. Patients with type 1 diabetes depend on external insulin for their survival because the hormone is no longer produced internally. Patients with type 2 diabetes are often insulin resistant and, because of…
