The gravitational constant, approximately 6989667400000000000â 6.674Ã10â11 Nâm2/kg2 and denoted by letter G, is an empirical physical constant involved in the calculation(s) of gravitational force between two bodies.
Diabetes insipidus is caused by a lack of antidiuretic hormone (ADH), also called vasopressin, which prevents dehydration, or the kidney's inability to respond to ADH. ADH enables the kidneys to retain water in the body. The hormone is produced in a region of the brain called the hypothalamus. It is stored and released from the pituitary gland, a small gland at the base of the brain. When diabetes insipidus is caused by a lack of ADH, it is called central diabetes insipidus.
Antidiuretic hormone, ADH or vasopressin. The antidiuretic hormone, ADH, also called vasopressin and arginine-vasopressin, is a nanopeptide (nine amino acids) synthesized in the hypothalamus, transported to and stored in the posterior lobe of the pituitary gland which releases it into the blood circulation.It has antidiuretic and vasopressor actions.ormed in the supra-optic and paraventricular nuclei of the hypothalamus by cleavages of a preprohormone of 168 amino acids and then a prohormone, vasopressin is transported to the posterior lobe of the pituitary gland which stores it.
