This intricate process, occurring in the endoplasmic reticulum following the removal of the signal peptide, results in proinsulin being cleaved into insulin and c-peptide. Consequently, c-peptide is a polypeptide originating from proinsulin after its cleavage in the B-cell, and importantly, it is secreted equimolarly with insulin. This equimolar secretion makes c-peptide a measure of endogenous insulin production and, in many clinical scenarios, a better marker of insulin secretion than insulin itself, as it is not subject to the same rapid degradation in the liverBiochemistry, C Peptide - StatPearls - NCBI Bookshelf - NIH.

The clinical utility of c-peptide measurements is extensive, serving as an aid in the diagnosis and treatment of various conditions related to abnormal insulin secretion, including diabetes mellitus. Its significance is particularly pronounced in differentiating types of diabetes and assessing residual beta-cell function. For instance, c-peptide measurements are also useful for assessing the insulin secretion capacity and therapeutic consequences in patients with diabetes. Furthermore, c-peptide levels are in many ways a better measurement of endogenous insulin secretion than peripheral insulin levels, offering a more reliable indicator of how much insulin the pancreas is actually producing.

In the context of diabetes classification, c-peptide plays a crucial role. While not a direct diagnostic test for the condition itself, c-peptide levels can be instrumental in distinguishing between Type 1 and Type 2 diabetes. In Type 1 diabetes, an autoimmune condition where the body attacks and destroys its own insulin-producing beta cells, c-peptide levels are typically very low or undetectable, indicating minimal to no endogenous insulin production. Conversely, in Type 2 diabetes, especially in the earlier stages, c-peptide levels may be normal or even elevated as the pancreas attempts to compensate for insulin resistance. The predictive ability of c-peptide in distinguishing Type 1 from other forms of diabetes is a significant area of research, with studies reporting a strong association between c-peptide levels and the classification and diagnosis of diabetes.C-Peptides for diagnostics and therapy: a veterinary ...

The role of C-peptide extends beyond mere classification. It is a valuable clinical biomarker, especially in autoimmune diabetes, where it helps assess the extent of beta-cell damage.The glucagon stimulatedC-Peptidedetermination is often used for differential diagnosis of insulin-dependent from non-insulin-dependent diabetic patients. For patients with premorbid insulin-requiring diabetes, a lower admission c-peptide level can be indicative of more severe beta-cell destruction.Review c-Peptide - American Diabetes Association Conversely, c-peptide measurements are proving to be a useful aid in the diagnosis of hypoglycemia and insulinoma, conditions characterized by either insufficient or excessive insulin production, respectively. The glucagon stimulated C-Peptide determination is often employed for the differential diagnosis of insulin-dependent from non-insulin-dependent diabetic patients.

It's important to note certain considerations when interpreting c-peptide resultsThe 1st International Reference Reagent (IRR) for humanC-peptide, in ampoules coded 84/510, has been widely used for the calibration of immunoassays for human .... For instance, c-peptide should not be assessed if hypoglycemia within the last 12 hours has occurred, as this can artificially affect levels. The c-peptide to insulin ratio can also provide valuable insights, particularly in critical care settings. In conditions like sepsis, this ratio can be significantly associated with inflammatory markers and disease severity in insulin-free septic patients, suggesting that sepsis can uncouple serum c-peptide and insulin levels.

The technical aspects of c-peptide measurement are also well-documented. Various assays are available, including the ELECTRA C-Peptide CLIA test, which is intended for the quantitative determination of circulating c-peptide in human serum for in vitro diagnostic use. Similarly, C-Peptide of Insulin ELISA kits are widely used.作者：M Crisman·2017·被引用次数：17—Premorbid insulin-requiring diabetes was independently associated with lower admission c-peptide, whereas greater plasma creatinine was independently associated ... The standardization of these measurements is an ongoing effort, with bodies like the C-Peptide Standardization Manufacturer Meeting actively working to ensure comparability of c-peptide measurements.

Beyond its role in diabetes, research suggests that c-peptides may perform numerous intrinsic biological roles, and some studies even indicate the possibility of specific c-peptide cell-surface receptors, challenging the long-held belief that it was a biologically inactive substance. This opens avenues for understanding its potential physiological functions beyond being a mere byproduct of insulin synthesis.
