Can Glutamate Bring Nitrogen To The Urea Cycle?

by

Can Glutamate Bring Nitrogen To The Urea Cycle? Glutamate, formed in the course of nitrogen elimination, is either oxidatively deaminated by liver glutamate dehydrogenase forming ammonia which is then incorporated into urea, or converted to glutamine by glutamine synthetase and transported to proximal tubule cells in the kidney. Does glutamate carry nitrogen? 4.1. From the

How Is Fumarate From Urea Cycle Transported To Tca Cycle?

How Is Fumarate From Urea Cycle Transported To Tca Cycle? Fumarate is then free to join the citric acid cycle, while arginine is degraded to urea and ornithine via the arginase enzyme. Ornithine is then transported back into the mitochondria via the ornithine-citrulline transporter, where the cycle can begin again. What connects urea cycle to
