BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Cholecystokinin (CCK) and gastrin together constitute a family of homologous peptide hormones, which are both physiological ligands for the gastrin/CCK-B receptor, whereas the CCK-A receptor binds only sulfated CCK-peptides. CCK peptides are mainly produced in small intestinal endocrine I-cells and in cerebral neurons.

Detailed explanation-2: -The gastrin family (also known as the gastrin/cholecystokinin family) of proteins is defined by the peptide hormones gastrin and cholecystokinin. Gastrin and cholecystokinin (CCK) are structurally and functionally related peptide hormones that serve as regulators of various digestive processes and feeding behaviors.

Detailed explanation-3: -Description. Gastrin and cholecystokinin (CCK) are structurally and functionally related peptide hormones that function as hormonal regulators of various digestive processes and feeding behaviors.

Detailed explanation-4: -Cholecystokinin is a hormone that functions as part of your digestive system. It’s released (secreted) by your small intestine during the digestive process. It’s sometimes called pancreozymin. Cholecystokinin is also found in your brain and central nervous system, though its function there isn’t as well understood.
