Identity

Space-filling 3D model of Hexarelin, carbon grey, nitrogen blue, oxygen red — Built from the SMILES on this record — the atoms, bonds and stereochemistry are exact. The shape is **one computed low-energy pose**, not a measured structure: a flexible peptide in solution has no single conformation. The skeletal formula below claims connectivity and nothing more, which is what we actually know.
