Oxyntomodulin (abbreviated to Oxm , Oxy ) is a peptide hormone that is released in the small intestine by so-called L cells during food intake and plays a role in people's feeling of satiety and appetite .

Oxyntomodulin is used experimentally for drug-assisted weight loss in the case of obesity , as it cushions feelings of hunger . Oxyntomodulin injected before meals caused weight loss in subjects. Furthermore, Oxyntomodulin promotes energy turnover.

It is believed that the hormone acts on the GLP-1 receptor ( glucagon-like peptide 1 receptor ). Like 7 other peptides - glucagon , glicentin, glicentin-related polypeptide (GRPP), glucagon-like peptide 1 (GLP-1, incretin hormone), glucagon-like peptide 1 (7-37), glucagon-like peptide 1 ( 7-36), Glucagon-like peptide 2 (GLP-2) - oxyntomodulin is produced by proteolysis from the glucagon precursor protein .
