Structural & Stability Notes
Sermorelin is a synthetic 29-amino-acid peptide corresponding to the biologically active N-terminal fragment of growth hormone–releasing hormone (GHRH 1–29). Its mid-length structure provides moderate conformational stability while remaining susceptible to enzymatic degradation in biological systems. Lyophilized storage under cold, dry conditions is recommended to maintain stability. Protection from moisture, light exposure, and repeated freeze–thaw cycles helps preserve structural integrity and maintain analytical consistency during laboratory research applications.
