Direct action of atrial natriuretic hormone
WebAtrial natriuretic peptide (ANP) is the first hormone isolated from the heart as a potent natriuretic, diuretic, and hypotensive factor. ANP has an intramolecular ring structure connected by two cysteine residues, and N-terminal and C-terminal extensions from it. ANP is present in mammals, amphibians, and bony fish, but absent in birds ... WebAtrial natriuretic peptide (ANP) or atrial natriuretic factor (ANF) is a natriuretic peptide hormone secreted from the cardiac atria that in humans is encoded by the NPPA gene. Natriuretic peptides (ANP, BNP, and CNP) are a family of hormone/paracrine factors that are structurally related. The main function of ANP is causing a reduction in expanded …
