What It Is

Insulin is an essential peptide hormone naturally synthesized by the beta cells of the pancreatic islets. Composed of two peptide chains (A and B) linked by disulfide bonds, it serves as the primary metabolic hormone regulating carbohydrate, fat, and protein metabolism by facilitating cellular glucose uptake.

What It Is Commonly Used For

• Glucose Transport & Homeostasis: Studied for its principal role in binding to insulin receptors to trigger GLUT4 translocation, facilitating glucose clearance from blood plasma into skeletal muscle and adipose tissue.

• Glycogen Synthesis & Storage: Evaluated in metabolic models for upregulating glycogen synthase, promoting cellular glucose storage within liver and muscle tissues.

• Nutrient Uptake & Protein Synthesis: Researched for its potent anabolic signaling mechanisms, driving cellular amino acid uptake, ribosome activation, and inhibition of intracellular proteolysis.

General Purpose

To provide an endogenous peptide hormone reference compound for investigating cellular nutrient transport, glucose homeostasis, glycogen storage pathways, and anabolic metabolic signaling in laboratory research.
