Orexin B (CAS 205640-91-1) – Appetite-Regulating Peptide API

Orexin B (CAS 205640-91-1) is a high-purity appetite-regulating peptide API, featuring ≥98% purity (HPLC-verified) and a defined 28-amino-acid structure (molecular weight: ~3870 Da). As a key orexin peptide, it binds to orexin receptors (OX1R/OX2R) in the hypothalamus to stimulate appetite, regulate energy expenditure, and maintain metabolic homeostasis—its core mechanism for food intake control.

This lyophilized peptide exhibits excellent water solubility and stable biological activity under proper storage. It is widely used in preclinical research on eating disorders, obesity, and metabolic disorders: it supports the construction of appetite regulation models, explores the role of orexins in energy balance, and aids in developing anti-obesity or appetite-modulating research tools. For pharmaceutical R&D teams, its specific receptor binding and consistent activity make it a reliable raw material for studying feeding behavior and metabolic regulation pathways.
