Vasopressins

Antidiuretic hormones released by the NEUROHYPOPHYSIS of all vertebrates (structure varies with species) to regulate water balance and OSMOLARITY. In general, vasopressin is a nonapeptide consisting of a six-amino-acid ring with a cysteine 1 to cysteine 6 disulfide bridge or an octapeptide containing a CYSTINE. All mammals have arginine vasopressin except the pig with a lysine at position 8. Vasopressin, a vasoconstrictor, acts on the KIDNEY COLLECTING DUCTS to increase water reabsorption, increase blood volume and blood pressure.

Also Known As:

Vasopressin; Pitressin; Vasopressin (USP); Hormone, Antidiuretic; beta Hypophamine; Antidiuretic Hormone; Antidiuretic Hormones; beta-Hypophamine
