Peptide Mechanistic Action

Meaning

Peptide mechanistic action describes the specific molecular and cellular pathways through which a biologically active peptide exerts its physiological effects on target tissues and cells. Unlike steroid hormones that often act via intracellular receptors, peptides typically bind to high-affinity receptors on the cell surface, initiating complex signal transduction cascades. Understanding this action is fundamental for developing novel peptide-based therapeutics in endocrinology and metabolic health.
