Normal Chemical Composition of Urine Urine is an aqueous solution of greater than 95% water, with a minimum of these remaining constituents, in order of decreasing concentration: Urea 9.3 g/L.

In general, around 7 to 20 mg/dL (2.5 to 7.1 mmol/L) is considered normal. But normal ranges may vary, depending on the reference range used by the lab, and your age. Ask your doctor to explain your results. Urea nitrogen levels tend to increase with age.

Urine is a liquid waste material produced in and excreted by the body. Secreted by the renal tubules, it accumulates in the urinary bladder and is excreted via the urethra. While it is composed of 91 to 96 percent water, it contains many other components, both solid and liquid.

A urinalysis test is performed by collecting a urine sample from the patient in a specimen cup. Usually only small amounts (30-60 mL) may be required for urinalysis testing. The sample can be either analyzed in the medical clinic or sent to a laboratory to perform the tests.

Most of it is excreted (removed from your body) in your urine, or passes through your intestines to regulate "normal" levels. Normal Uric acid levels are 2.4-6.0 mg/dL (female) and 3.4-7.0 mg/dL (male). Normal values will vary from laboratory to laboratory. Also important to blood uric acid levels are purines.

Urine is an aqueous solution of greater than 95% water, with a minimum of these remaining constituents, in order of decreasing concentration: Urea 9.3 g/L. Chloride 1.87 g/L. Sodium 1.17 g/L.

Metabolic wastes like urea, carbon dioxide, uric acid, creatinine and sodium chloride are present in normal urine. The presence of proteins, glucose, ketones, red blood cells, however, indicate malfunction of the kidneys or some other organ of the body.

The only way to know if you have protein in your urine is to have a urine test. The test for protein in the urine measures the amount of albumin in your urine, compared to the amount of creatinine in your urine.

Having sugar in your urine is usually a sign of very high blood sugar levels. The extra sugar in the bloodstream is usually only removed via the kidneys and detectable in urine at blood sugar concentrations of 10 mmol/L (180 mg/dL) and above.

Urea consists of carbon, nitrogen and oxygen. You can find it in urine, sweat, blood and milk in mammals. In its most concentrated form, it is urine.

They are ammonia, urea, uric acid, and creatinine. All of these substances are produced from protein metabolism. In many animals, the urine is the main route of excretion for such wastes; in some, the feces is.

Given Urea= NH2- CO- NH2 And we know that Total mass of urea = 60 Mass of nitrogen = 14 Two molecules of nitrogen= 2*14= 28 Percentage of nitrogen = Mass of Nitrogen/(Urea ) x 100 = 28/60 x 100 = 46.6% Hence Percentage of nitrogen in urea is 46% Option A is the right answer.

Normal Uric acid levels are 2.4-6.0 mg/dL (female) and 3.4-7.0 mg/dL (male). Normal values will vary from laboratory to laboratory. Also important to blood uric acid levels are purines.

Normal urine creatinine values generally range from 955 to 2,936 milligrams (mg) per 24 hours for males, and 601 to 1,689 mg per 24 hours for females, according to the Mayo Clinic. Creatinine values that fall outside the normal range may be an indication of: kidney disease.

Urea Fertilizer: 46-0-0 It means that it contains 46% nitrogen (N), zero phosphorus, and zero potassium. Thus 100 kg of granular urea supplies 46 kg N with the remainder consisting of carriers or fillers.

A blood urea nitrogen (BUN) test measures the amount of nitrogen in your blood that comes from the waste product urea. Urea is made when protein is broken down in your body. Urea is made in the liver and passed out of your body in the urine. A BUN test is done to see how well your kidneys are working.

An Urinometer is a simple piece of equipment for determining urine specific gravity. A typical urinometer is composed of a float, a weight, and a stem.
