Insulin (fra latin: insula, dvs. øy) er et polypeptid-hormon som produseres av cellegrupper kalt langerhanske øyer i bukspyttkjertelen og utskilles til blodet avhengig av matinntak og blodsukkernivå. Insulin står sentralt i kroppens sukker-/karbohydrat-/glukose-metabolisme, og underskudd på insulin fører til diabetes mellitus, tidligere kalt sukkersyke. For lite insulin ved diabetes gir høyt blodsu… NettetNational Center for Biotechnology Information
