Cholecystokinin, an update

Many papers in the literature focused on cholecystokinin for some years. It is a group of small peptides which act at several levels in the organism. Cholecystokinin plays an important role in nutrition, food regulation and satiety signaling. This article presents the biosynthesis and structure of this family of peptides, the cholecystokinin receptors and the digestive, nutritional, metabolic and satiety control exerted by these regulatory peptides. The psychobehavioral aspects of cholecystokinin are not described here in details. [Copyright &y& Elsevier]
