lysine vasopressin

Lysine vasopressin has a lysine in place of the arginine.

A very similar substance, lysine vasopressin (LVP) or lypressin, has the same function in pigs and is often used in human therapy.

(In swine, which do not produce arginine vasopressin, lysine vasopressin acts synergistically with CRH.)

Lysine vasopressin, a modified form of the vasopressin molecule, had positive effects on memory when administered by injection to patients with amnesia resulting from traumatic brain injury and Korsakoff's Syndrome.
