a thick, brown-green fluid secreted by the liver which is alkaline in its reactions, containing bile salts, bile pigments, CHOLESTEROL and inorganic salts. Bile is transferred from the liver to the DUODENUM via the bile duct which in many mammals contains a reservoir called the gall bladder.
Vasopressin, also known as arginine vasopressin (AVP), antidiuretic hormone (ADH), or argipressin, is a neurohypophysial hormone found in most mammals.Its two primary functions are to retain water in the body and to constrict blood vessels.asopressin regulates the body's retention of water by acting to increase water reabsorption in the kidney's collecting ducts, the tubules which receive the very dilute urine produced by the functional unit of the kidney, the nephrons.
Interaction mechanism of the substituted residue Lys292 in the binding sites of some viral N1 and N9 neuraminidases were investigated [15, 20]. However, how this R292K (R289K in H7N9 numbering) mutation affects the inhibitor-binding site of the novel avian influenza A (H7N9) virus has not yet been understood.
