Summary

Insulin is derived from proinsulin and its secretion varies throughout the day in response to mealtimes. Insulin acts as a ‘gatekeeper’ for glucose, allowing it to enter cells.

Insulin plays a key role in maintaining appropriate levels of glucose in the blood, an essential process called glucose homeostasis. People with diabetes have high glucose due to insulin insufficiency. Therefore, they may need insulin therapy.

Human insulins were launched in the 1980s. There are different insulin preparations with different acting speeds (from rapid to long-acting).
