The delicate TM, crucial for cellular physiological stability, is susceptible to environmental influences
Two key structural features distinguish it from other GHRPs: (1) incorporation of an -aminoisobutyric residue (Aib) at position 1 replacing the histidine of classical GHRPs, stabilising the -turn conformation required for receptor activation, (2) presence of a D-2-naphthyl-alanine (D-2-Nal) at position 3 replacing the D-isomer tryptophan, increasing GHS-R1a selectivity over related receptors
