Bioactive peptides obtained from marine species and marine by-products are showing these days a great interest
in nutraceutical and pharmaceutical applications due to their wide range of biological activities. This mini-review focuses
on the potential of marine peptides to be used as appetite suppressive molecules in the prevention and/or in the
treatment of obesity syndrome. An important and promising aspect in the fight against obesity is the study of anorexigenic
gut hormones, like cholecystokinin (CCK) and glucagon-like peptide 1 (GLP-1), that are synthetized by enteroendocrine
cells in the presence of nutrients in the gastrointestinal tract. Recent works which have focused on the interaction between
marine peptides and CCK and GLP-1 are here reviewed.
Keywords: Bioactive peptides, cholecystokinin, food intake, glucagon-like peptide-1, marine organisms, protein hydrolysate.
