Researched for: Vendor-neutral scientific reference catalog record for insulin
Also known as: human insulin, insulin human, INS
Mature human insulin is a 51-residue peptide hormone composed of A and B chains linked by disulfide bonds. It is produced from the INS gene as preproinsulin, processed through proinsulin, and secreted by pancreatic beta cells. Insulin lowers blood glucose and promotes cellular uptake and storage of metabolic substrates. The term insulin encompasses species-specific native proteins, recombinant human insulin, and multiple sequence-modified insulin analogs; pharmacokinetic and handling properties therefore depend on the specific preparation.
Source review pending. This descriptive profile is shown from the available source material as a best-effort educational reference. It has not passed the full verification bar and is not a dosing instruction, medical claim, or treatment recommendation.
Reflects preclinical/research literature context only. Not a medical claim, dosing instruction, or treatment recommendation.
Insulin is not a single uniform pharmaceutical preparation. Regular human insulin, intermediate-acting formulations, mixtures, and rapid-, short-, intermediate-, and long-acting analogs differ in sequence, excipients, concentration, route restrictions, onset, duration, and half-life. Pharmacokinetic values and administration timing should therefore be recorded only against a specified insulin preparation and official product label or study.

CAS RN 9004-10-8; UniProt human INS precursor accession P01308
Human insulin consists of an A chain of 21 amino acids and a B chain of 30 amino acids. The human INS precursor is 110 amino acids long and is processed to the mature hormone. Native insulin can assemble into dimers and zinc-associated hexamers; formulation-dependent association state may affect biophysical behavior.
