Insulin in solution is reasonably stable. Sterile solutions can be stored at 2–8 °C for up to 12 months. Should freezing be preferred, solutions may be stored frozen at -20°C in single-use aliquots. Freeze-thaw cycles should be avoided.

General description
Listen to an Audio Overview
The INS gene encodes for preproinsulin, which is enzymatically converted into insulin.[1] Insulin is produced in the insulin-producing pancreatic β cells.[2] Preproinsulin is converted to proinsulin in ER and proinsulin is then proteolytically processed to form insulin in newly-forming insulin secretory granules.[3] Insulin production is tightly regulated by specific DNA elements present within ∼400 bp in the proximal region of the INS promoter.[4]

Application
Biochem/physiol Actions
Insulin is responsible for two types of actions- excitatory and inhibitory. In its excitatory role, it increases the uptake of glucose and lipid synthesis, and in its inhibitory role it inhibits glycogenolysis, gluconeogenesis, lipolysis, proteolysis and ketogenesis.[8] Aberrant insulin secretion leads to various disorders such as diabetes, hyperglycemia or hypoglycaemia.[2] Type I diabetes is a result of autoimmune destruction of β cells of pancreas, which leads to depletion of insulin.[9] Mutant INS-gene Induced Diabetes of Youth (MIDY) syndrome is an autosomal dominant disorder caused by missense mutations, which lead to aberrant proinsulin folding.[3] Impaired glucose tolerance (IGT) or non-insulin-dependent diabetes mellitus (NIDDM) is caused by resistance to insulin-stimulated glucose uptake.[10]
Regulates the cellular uptake, utilization, and storage of glucose, amino acids, and fatty acids and inhibits the breakdown of glycogen, protein, and fat.
Two-chain polypeptide hormone produced by the β-cells of pancreatic islets. Its molecular weight is ~5800 Da. The α and β chains are joined by two interchain disulfide bonds. The α chain contains an intrachain disulfide bond. Insulin regulates the cellular uptake, utilization, and storage of glucose, amino acids, and fatty acids and inhibits the breakdown of glycogen, protein, and fat.
