Question

Why glucose is not found in the urine of a healthy person?

Answer 1

Urine:

1. Urine is a transparent yellow liquid with a pH of roughly $6$, making it mildly acidic.
2. The presence of urochrome, a pigment generated by the breakdown of hemoglobin, gives urine its yellow color.
3. The color and pH of urine might change depending on a person's diet.

Composition of urine:

1. Urine normally contains around $95\%$ water and $5\%$ solid waste, which includes both organic and inorganic components.
2. In the proximal region of the nephron, glucose is reabsorbed into the bloodstream.
3. As a result, a normal healthy person's urine is glucose-free.
