The urea is a nitrogenous compound containing a carbonyl group attached to two amine groups with osmotic diuretic activity. It is a carbonyl group with two c-bound amine groups. It is one carbon compound, and it comes from carbonic acid.
It is odorless, colorless, extremely soluble in water, and almost nontoxic. When it is dissolved in liquid, it does not have an alkaline property or an acidic property. The urea is produced in the liver through the urea cycle from ammonia and manufactures protein metabolism.
The urea management raises blood plasma osmolality, causing the enhanced flow of water from tissues, including the brain, cerebrospinal fluid, and eye, into the interstitial fluid and plasma, which decreases strain in these tissues and improves outflow.
