Obestatin(rat) is primarily used in research studies focused on understanding its role in regulating appetite and energy balance. It is often employed in experimental models to investigate its effects on food intake, body weight, and metabolic processes. Researchers also explore its potential interaction with other hormones involved in hunger and satiety, such as ghrelin. Additionally, obestatin(rat) is utilized in studies examining its influence on gastrointestinal motility and its possible therapeutic applications in metabolic disorders like obesity and diabetes. Its use is confined to laboratory settings, particularly in animal studies, to advance scientific knowledge in endocrinology and metabolism.
