Hunger Peptides

The PepTalk this week delves into some new research that looks into hunger and the interactions between gut hormones and the brain. Some peptides, such as bombesin, cholecystokinin (CCK), and ghrelin, alert the brain of hunger status. While others, including agouti-related peptide (AGRP), galanin, and Neuropeptide Y (NPY), increase the production of neurotransmitters.1 Meanwhile, appetite is decreased alongside levels of alpha-melanocyte stimulating hormone (α-MSH), cocaine and amphetamine-regulated transcript (CART), and neurotensin.2 Here is a selection of peptides for hunger research that are available from stock at Peptides International:
