Brain natriuretic peptide, uretic peptide or Ventricular Natriuretic Peptide (still BNP), is a 32-amino acid polypeptide secreted by the ventricles of the heart in response to excessive stretching of heart muscle cells (cardiomyocytes). BNP is named as such because it was originally identified in extracts of porcine brain, although in humans it is produced mainly in the cardiac ventricles.https://www.creative-peptides.com/product/brain-natriuretic-peptide-human-item-10-101-25-19.html
