Des-Gln14-Ghrelin (rat) TFA is primarily utilized in research settings to study the physiological roles of ghrelin, a hormone involved in appetite regulation and energy balance. It is often used in experiments to investigate the mechanisms of hunger, food intake, and metabolic processes. Researchers employ this peptide to explore its effects on growth hormone secretion and its interaction with the ghrelin receptor (GHSR). Additionally, it serves as a tool in studies related to obesity, diabetes, and other metabolic disorders, helping to understand the pathways and potential therapeutic targets for these conditions. Its application is critical in advancing knowledge of endocrine signaling and metabolic health.
