There are about 200 grams of protein in the blood plasma and normally none in the urine. What mechanism keeps protein out of the urine, and what structure would be potentially damaged if protein was found in significant amounts in urine.

The kidney initially uses Glomerular filteration of the blood.. (kinda like coffee going through a filter) this process will not allow red blood cells and larger proteins to enter the nephron, but the water, glucose and Amino Acid can pass through. Reabsorption would then be responsible for taking any amino acids and glucose out of the urine and returning to the blood with active transport ..

Urine is made up of parts of the blood plasma that are selected by the kidneys. Nothing can get to the urine without going through the blood so in a way all of your urine is blood plasma.

Protein should be filtered by the glomerulus - it should never enter the urine. Therefore, protein in the urine indicates damage to the glomerulus structures, which can have a number of different causes.

Protein is synthesized in cells in order to carry out specific functions. Urine is a waste product, so it shouldn't have any proteins in there. Besides, if there were, other organs like the kidney or small intestine would filter out usable proteins.

Glomerular basement membrane prevents the filtration of protein in toto.
