Uric acid is a substance that results from the breakdown of purines. A normal part of all human tissue, purines are found in many foods. Normally, uric acid is dissolved in the blood and passed through the kidneys into the urine, where it is eliminated.
If there is an increase in the production of uric acid or if the kidneys do not eliminate enough uric acid from the body, levels of it build up in the blood (a condition called hyperuricemia). Hyperuricemia also may result when a person eats too many high-purine foods, such as liver, dried beans and peas, anchovies, and gravies. Hyperuricemia is not a disease, and by itself it is not dangerous. However, if excess uric acid crystals form as a result of hyperuricemia, gout can develop. The crystals form and accumulate in the joint, causing inflammation. (acknowledgment of source The National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS)
The concentration of urea is high in urine because urea is a waste product produced by the liver when it breaks down proteins. The kidneys then filter urea from the blood and excrete it in urine to maintain the body's nitrogen balance.
The primary source of nitrogenous waste in animals is the breakdown of proteins and amino acids. This breakdown releases nitrogen-containing compounds like ammonia, urea, or uric acid, which must be excreted from the body to maintain proper nitrogen balance.
Urea is commonly used in fertilizers to provide a source of nitrogen for plants. It is also utilized in the production of cosmetics, lotions, and creams as a moisturizing agent. In addition, urea is used in certain medical tests to analyze kidney function.
The urea cycle takes place in the liver.
Kidneys
The body removes urea through the kidneys via urine. Urea is a waste product produced in the liver during protein metabolism. It is filtered out of the blood by the kidneys and eliminated from the body through urination.
Urea is produced in the liver as a waste product of protein metabolism. It is then filtered by the kidneys, where it is excreted in urine. Urea helps regulate the body's nitrogen balance and helps to remove toxic ammonia from the body.
Urea is made in the body by the liver, it is a by product produced in the process of removing ammonia, Ammonia is extremely toxic for the human body. Urea is then excreted from the blood filtered through the kidneys.
Diazolidinyl urea is produced by the chemical reaction of allantoin and formaldehyde in the presence of sodium hydroxide solution and heat. The reaction mixture is then neutralized with hydrochloric acid and evaporated. Note: Diazolidinyl urea is an antimicronbial preservative used in cosmetics. It is chemically related to imidazolidnyl urea which is used in the same way. Diazolidinyl urea acts as a formaldehyde releaser. Commercial diazolidinyl urea is a mixture of different formaldehyde addition products including polymers. source: http://en.wikipedia.org/wiki/Diazolidinyl_urea
Excess urea in the body is primarily removed by the kidneys through urine excretion. Increasing fluid intake can help dilute urea levels and promote its excretion. In severe cases, dialysis may be necessary to remove excess urea from the blood.
Excess nitrogen is converted into urea by the liver through a process called the urea cycle. Urea is then excreted in urine by the kidneys to maintain nitrogen balance in the body.
when your liver assimilates proteins the excess is broken down into urea which is then excreted in urine.
