2021年11月1日 · Insulin production is part of an endocrine process in the liver that controls blood sugar. Insulin helps the body break down fats, carbohydrates, and proteins from food to be used for energy. Insulin resistance develops when cells in your muscles, fat, and liver are unable to use insulin properly, resulting in high blood sugar.

2024年4月24日 · Insulin is a hormone your body makes that helps it control your blood sugar level and metabolism — the process that turns the food you eat into energy.

Insulin enhances glucose uptake and metabolism in the cells, thereby reducing blood sugar. Their neighboring alpha cells, by taking their cues from the beta cells, [10] secrete glucagon into the blood in the opposite manner: increased secretion when blood glucose is low, and decreased secretion when glucose concentrations are high.

2014年2月1日 · Regulation of insulin secretion is coupled to metabolism and electrophysiologic events involving plasma membrane depolarization and calcium-ion homeostasis. The insulin receptor is a transmembrane protein containing an extracellular hormone-binding domain and intracellular tyrosine kinase domain.

Insulin is the paramount anabolic hormone, promoting carbon energy deposition in the body. Its synthesis, quality control, delivery, and action are exquisitely regulated by highly orchestrated intracellular mechanisms in different organs or “stations” of its bodily journey.

Insulin is a hormone that regulates the amount of glucose (sugar) in the blood and is required for the body to function normally. Insulin is produced by cells in the pancreas, called the islets of Langerhans.

Insulin is a polypeptide hormone mainly secreted by β cells in the islets of Langerhans of the pancreas. The hormone potentially coordinates with glucagon to modulate blood glucose levels; insulin acts via an anabolic pathway, while glucagon performs catabolic functions.

2025年1月21日 · Insulin acts primarily to stimulate glucose uptake by three tissues— adipose (fat), muscle, and liver —that are important in the metabolism and storage of nutrients. Like other protein hormones, insulin binds to specific receptors on the outer membrane of its target cells, thereby activating metabolic processes within the cells.

2022年9月26日 · Insulin is an anabolic hormone that elicits metabolic effects throughout the body. In the pancreas, exocrine tissue known as the islets of Langerhans contain beta cells. Beta cells are responsible for insulin synthesis.

2024年2月8日 · Insulin is a peptide hormone produced by beta cells within the pancreas. It is responsible for regulating the movement of glucose from the blood into cells. It is released in an endocrine fashion into the bloodstream.
