The vasopressin is a protein, which has a bisulphide bond at two amino acid sequences and readily forms the channel, (42) whereas urea may not be able to form the channel-like vasopressin but, being a crystalloid particle, draws water more actively than vasopressin, thereby resulting in decreased [L.
