Research Overview
Cholecystokinin-8
CCK-8 is a canonical gut hormone fragment with extensive documentation in digestive physiology and appetite control. Sulfation of the tyrosine residue is important for high-affinity receptor activity.
Insulin Glargine
Clinical and translational studies support its use as a basal comparator because of prolonged absorption and stable glycemic control. It is heavily used in basal-bolus regimen research and insulin-delivery optimization studies.
