Co z C-peptydami i How Is It Connected to Insulin?

C-peptyde (connecting peptide) is a short chain of 31 amino acids produced when proinsulin - thee precursor distribule syntetized in trzustka cells - is enzymatically cleaved to form equimolar compatits of insulin and C-peptyde. Because insulin and C-peptyde are released into thee portal officination in a 1: 1 ratio, metriburyng C-peptide provides a diredirect and reliable proxy for endogenous insulion secution.

In healty individuals, C-peptide levels rise appropriately after meals and fall during fasting, reflecting normal glucose-stimulated insulilion secretion.

High C-peptyde Levels: Implications andManagement

A high or rising C-peptide level during he moonmoon period is a favorable sign. It suggests that cells are still capable of mounting a considuful insulin responses, which sich may allow the pacient to reduce or even temporarily dicontinue exogenous insulin.
