linsulina

Linsulina is not a widely recognized term in biomedical literature. In many cases, it appears to be a misspelling or language variation of insulin, the hormone that regulates blood glucose, rather than a distinct biochemical entity. Because the term lacks a formal, independent definition in standard pharmacology references, its meaning is often inferred from context or from the ordinary word insulin in non-English languages such as Spanish, Portuguese, or Italian, where "insulina" is the standard spelling for the same hormone.

Insulin is a peptide hormone produced by pancreatic beta cells. It plays a central role in carbohydrate and fat metabolism by promoting uptake of glucose into liver, muscle, and adipose tissue and by inhibiting glucose production by the liver. Its action begins when it binds to the insulin receptor on target cells, triggering a signaling cascade that includes GLUT4 translocation to the cell membrane.

In medicine, insulin is used to treat diabetes mellitus and is available as multiple formulations with different onset and duration of action. It is typically administered by subcutaneous injection or via an insulin pump. The development of recombinant human insulin and various analogs has expanded dosing options and delivery routes. Common considerations include monitoring blood glucose to avoid hypoglycemia and dose adjustments for activity, illness, or other medications.
