a waste product of the metabolism of proteins that is formed by the liver and secreted by the kidneys
an organic compound of carbon, nitrogen, oxygen, and hydrogen; produced in the liver under the control of N-acetylglutamate.
A non-protein nitrogen usually fed with molasses.
A waste product found in the blood and caused by the normal breakdown of protein. Urea is normally removed from the blood by the kidneys and then excreted in the urine. Urea accumulates with kidney failure.
A nitrogenous end product of protein metabolism, normally secreted by the kidney.
a waste product of metabolism eliminated via the kidneys. In elasmobranchs (sharks, rays, skates), urea is found in the blood where it helps to maintain osmotic balance
a component of urine that results from amino acid breakdown in the liver.
A compound formed in the liver from ammonia and later excreted by the kidneys. It is the principle end product of of protein breakdown
The diamide of carbonic acid found in blood, lymph, and urine. It is formed from ammonia derived from amino acids in the liver. The amount of urea excreted is dependent upon the amount of protein in the diet. Excretion increases with fever, diabetes, and increased activity of the adrenal gland.
A waste product of digested protein normally filtered out by the kidneys and excreted from the body in urine.
A compound found in urine and other bodily fluids, synthesized from ammonia and carbon dioxide.
Gk. ouron, urine] A soluble form of nitrogenous waste excreted by mammals and most adult amphibians.
A white, crystalline, substance found in urine, blood, and lymph, which is the final product of protein metabolism in the body. Synthetic urea can be used by ruminal bacteria as a nitrogen source for protein synthesis.
the main nitrogen part of urine made from protein breakdown
The main nitrogenous component of urine, resulting from the breakdown of amino acids.
The final byproduct of protein metabolism in man.
the chief solid component of mammalian urine; synthesized from ammonia and carbon dioxide and used as fertilizer and in animal feed and in plastics
A product of protein breakdown of amino acids, excreted in the urine.
A nitrogen-containing substance normally cleared from the blood by the kidney into the urine . Diseases that compromise the function of the kidney often lead to increased blood levels of urea, as measured by the blood urea nitrogen ( BUN ) test. See the entire definition of Urea
u-REE-ah A nitrogenous waste derived from ammonia. 776
one of the nitrogenous waste products of protein metabolism. Urea is formed in the liver as the end product of protein metabolism.
MS = A compound formed in the liver from ammonia produced by the deamination of amino acids. It is the principal end product of protein catabolism and constitutes about one half of the total urinary solids. UI = D014508
A nitrogen-containing waste product excreted in the urine of many vertebrates
The chief product of nitrogen metabolism in mammals, excreted in the urine. Carbonyl diamide.
A form of nitrogen that converts readily to ammonium.
Nitrogenous waste product formed during the breakdown of protein in the body.
the nitrogen part of urine produced from the breakdown of protein.
The waste product of protein metabolism, made by the liver and removed from the body via the kidneys.
a substance found in urine, blood, and lymph; the main nitrogenous substance in blood
A synthetic nitrogen compound used as a humectant in printing and painting with all classes of dyes. It also increases the solubility of the dyes.
one of the waste products that build up in the blood. The levels of urea in the blood can be measured to give an indication of how well, or poorly, the kidneys are working.
A compound serving as the main excreted form of nitrogen by many animals, including mammals.
Urea is a by product of the water-toluene diisocyanate reaction during flexible polyurethane foam production. The urea forms short length polymer cross links between the long polyurethane chains, which adds firmness to the foam.
Nitrogen-containing compound generated by the breakdown of ingested proteins.
A crystalline colorless nitrogenous compound found primarily in the urine of mammalian animals; can be synthesized from carbon dioxide and ammonia for use in fertilizers, resins, and plastics.
A waste product in the blood that comes from the breakdown of food protein. The kidneys filter blood to remove urea. As kidney function decreases, the BUN level increases. Urea can indicate how well the kidneys are functioning, although other factors can alter this level. Continuous Cycling Peritoneal Dialysis (CCPD): Form of CPD in which a machine called an automatic cycler performs regular exchanges throughout the night.
One of the chief waste products of the body. When the body breaks down food, it uses what it needs and throws the rest away as waste. The kidneys flush the waste from the body in the form of urea, which is in the urine.
A single-nutrient fertilizer that contains a large amount of nitrogen and is manufactured from ammonia and carbon dioxide. It is also used in resin adhesives. up
the major nitrogen-containing product of protein catabolism.
The primary solid component of mammalian urine that is the product of protein breakdown.
A byproduct of protein metabolism in the body, and the chief nitrogenous constituent of urine.
a nitrogen-containing waste product from the breakdown of proteins that is excreted in the urine. Urea is produced in the liver by the condensation of two molecules of ammonia and one molecule of carbon dioxide.
Urea is the primary waste product in urine. The excretion of urea in the urine is the body's principal route for eliminating excess nitrogen-containing by-products of protein metabolism. Edgar Cayce sometimes noted the urea level of the blood, particularly if the body were becoming toxic. Urea is created in the liver and carried by the bloodstream to the kidneys where it is removed from the blood and concentrated for excretion in the urine. The transfer of urea from the liver to the kidneys is part of the process which Cayce called the "lower hepatic circulation" (circulation between the liver and kidneys).
a water-soluble compound that is the major nitrogenous end product of protein metabolism and is the chief nitrogenous component of the urine in mammals and other organisms. Also called carbamide.
Chief waste products of the body. The kidneys flush the waste from the body in the form of urea, which is in the urine. The synthetic form is widely used in cosmetics as moisturizer.
Major waste product of protein degradation. Contains amino groups.
a nitrogenous waste product resulting from the break down of proteins. It is excreted in urine Humans as organisms
Urea is an organic compound of carbon, nitrogen, oxygen and hydrogen, with the formula CON2H4 or (NH2)2CO.
