Proinsulin is synthesized in the beta cells of the pancreas and is the precursor molecule for insulin. Most proinsulin is converted to insulin and C-Peptide, which are secreted in equimolar amounts into the blood. About 15% is not converted and is released as proinsulin. The biological activity of proinsulin is only about 10% of Insulin, but the half-life of proinsulin is three times as long as insulin. The level of proinsulin in serum can be a reflection of β cell status. Both IDDM and NIDDM are characterized by dysfunction of the pancreatic beta cells. Elevated proinsulin levels have been noted at the onset of IDDM and in healthy siblings of IDDM patients. Proinsulin levels may also be increased in patients with established NIDDM. In
