PPT-Urea Cycle DR AMINA TARIQ

BIOCHEMISTRY Urea is the major disposal form of amino groups derived from amino acids and accounts for about 90 of the nitrogencontaining components of urine One nitrogen of the urea molecule is supplied by free NH.

Prof. Tariq Waseem. Case 1. A 55 yrs old university professor has noticed chest tightness and heaviness while walking a distance of 300 meters from car parking to his department. The feeling is relieved if he stops midway for a while and does not occur at all when he walks in company of his colleagues or students. He felt similar chest congestion going uphill in Murree during last summer vacations. A friend suggested a pill to be kept in mouth while walking and he felt relieved.. .. Urea contributes to the establishment of the osmotic gradient in the . medullary. pyramids and the ability to form a concentrated urine in the collecting ducts. Urea transport is mediated by urea transporters, presumably by facilitated diffusion.
