Sermorelin is a synthetic peptide consisting of the first 29 amino acids of human GH-related research-releasing hormone (GHRH). As a GHRH analog, Sermorelin has been studied extensively in research contexts examining GH-related research physiology and the hypothalamic-pituitary axis. This review examines the research landscape surrounding this peptide compound.
Molecular Structure and Properties
Sermorelin (GHRH 1-29) represents the biologically active portion of the 44-amino acid native GHRH molecule:
- Molecular weight: approximately 3,358 Da
- Sequence: First 29 amino acids of GHRH
- Retains biological activity of full-length GHRH
- Water-soluble peptide suitable for various research applications
Research has established that the N-terminal 29 amino acids contain the structural elements necessary for receptor binding and biological activity.
GHRH Receptor Interactions
Sermorelin interacts with the GHRH receptor (GHRHR), a G protein-coupled receptor expressed primarily on pituitary somatotroph cells:
Receptor Binding Studies
Research has characterized Sermorelin’s binding affinity and kinetics at the GHRH receptor. These studies have used radioligand binding assays and other techniques to quantify receptor interactions.
Signal Transduction
