Differences in receptor binding and stability to enzymatic digestion between cck-8 and cck-58

Introduction and AimsIt has been proposed that distinct tertiary structures of the C-terminus of CCK-8 and CCK-58 result in differences in stimulation of pancreatic amylase secretion. Binding of CCK-8 and CCK-58 to CCK-A and CCK-B receptors and stability to enzymatic digestion were used as independe
