Rectal and oral administration of L-Phenylalanine supresses food intake and modulates neuronal activation in appetite-regulating brain regions in rodents

High protein diets are highly satiating but hard to maintain. By understanding the mechanisms underlying these effects we may be able to identify new anti-obesity therapies. Protein is broken-down into amino acids in the gut which are detected by a series of nutrient sensors. The calcium sensing receptor (CaSR) is primarily activated by calcium ions, but is positively allosterically modulated by aromatic amino acids, especially L-phenylalanine. Sti...

High protein diets suppress appetite, but are difficult to adhere to. Understanding how the gut senses protein may identify mechanisms to drive satiety. Amino acid products of protein digestion are thought to be sensed by G protein coupled receptors in the gut, including the calcium sensing receptor (CaSR). Calcium ions are the major ligand of the CaSR, but aromatic amino acids, particularly L-phenylalanine (L-Phe), allosterically modulate CaSR activity....
