Abnormal components of urine

Composition of Urine

i) Normal human urine

About 95% of urine consists of H2O. Organic substances include urea, creatinine, ammonia, uric acid, hippuric acid, oxalic acid, amino acids, vitamins, hormones and enzymes. Inorganic substances include chlorides, phosphates, sulphates, potassium, sodium, calcium, magnesium, iodine, arsenic and lead.

It is transparent, pale yellow slightly acidic (pH = 6.8) fluid with specific gravity of 1.015 – 1.02. The pale yellow colour is due to the urochrome pigment which is the byproduct of haemoglobin breakdown. On standing, urine becomes cloudy and acquires ammonical odour due to the bacterial degradation of urea and ammonium carbonate.Visit Biology Doubts page of Physics Wallah for more questions.
