Semaglutide is a glucagon-like peptide-1 receptor agonist (GLP-1 RA). It goes by various trade names, for use in certain medications. However we are delving into how it works to best apply it to scientific experiments you are planning to perform.

  1. Mechanism of Action:
    • Semaglutide mimics the action of the natural hormone glucagon-like peptide-1 (GLP-1).
    • GLP-1 plays a crucial role in regulating blood sugar levels.
    • By binding to GLP-1 receptors, semaglutide triggers several beneficial effects.
  2. How Semaglutide Works Internally:
    • Insulin Secretion: Semaglutide stimulates insulin secretion from the pancreas. When blood glucose levels are high, it prompts the pancreas to release more insulin. Insulin helps lower blood sugar by facilitating glucose uptake into cells.
    • Glucagon Inhibition: Semaglutide also inhibits the secretion of glucagon. Glucagon is a hormone that raises blood sugar levels by promoting the release of stored glucose from the liver. By reducing glucagon levels, semaglutide helps maintain better blood sugar control.
    • Slowing Gastric Emptying: Semaglutide slows down the emptying of the stomach after meals. This effect helps regulate the rate at which glucose enters the bloodstream, preventing rapid spikes.
    • Appetite Regulation: Some studies suggest that semaglutide may influence appetite centers in the brain, leading to reduced food intake and potential weight loss.
  3. Clinical Applications:
    • Type 2 Diabetes: Semaglutide is primarily used to manage type 2 diabetes. By improving blood sugar control, it reduces the risk of complications associated with high glucose levels.
    • Obesity: Semaglutide has gained attention as an effective treatment for obesity. Its appetite-suppressing effects contribute to weight loss.
  4. Administration:
    • Subcutaneous injection is typically administered

In summary, by enhancing insulin secretion, inhibiting glucagon, and regulating appetite, semaglutide contributes to better metabolic control.
