Catecholamine
Catecholamine — A class of hormones including dopamine, norepinephrine, and epinephrine derived from tyrosine, often co-studied with neuropeptides in stress response research.
What Is a Catecholamine?
Catecholamines (dopamine, norepinephrine, epinephrine) are monoamine neurotransmitters derived from tyrosine. While not peptides themselves, catecholamines interact extensively with peptide systems: neuropeptide Y (NPY) is co-released with norepinephrine, enkephalins are co-stored with catecholamines in adrenal chromaffin granules, and peptide hormones regulate catecholamine synthesis and release.
Peptide Connections
- NPY: 36-residue neuropeptide co-released with norepinephrine. Regulates appetite and stress
- Chromogranins: Catecholamine storage proteins processed into bioactive peptides (catestatin, vasostatin)
- BPC-157: Modulates dopaminergic system in preclinical research models
