Peptide YY porcine is primarily used in research settings to study its role in appetite regulation and gastrointestinal functions. It is often employed in physiological and pharmacological studies to understand its effects on reducing food intake and slowing gastric emptying. Researchers utilize this peptide to explore its potential therapeutic applications in treating obesity and related metabolic disorders. Additionally, it is used in biochemical assays to investigate its interaction with specific receptors in the body, providing insights into its mechanisms of action. Its application extends to preclinical studies aimed at developing peptide-based therapies for conditions involving dysregulated appetite and digestion.
