1. John Boyd Orr he published influential papers on protein metabolism in man. 2. Sharpenak s long-term studies of protein metabolism have received worldwide recognition. 3. Therefore, measuring nitrogen inputs and losses can be used to study protein metabolism . 4. The end-product of catabolism of protein metabolism in animals is nitrogen. 5. Sharpenak s studies of protein metabolism have gained international recognition. 6. Biotin is important for tissue growth, as well as for fat and protein metabolism . 7. For six decades, Munro studied the biochemical effects of nutritional change, particularly protein metabolism . 8. Alterations in protein metabolism may also produce pellagra-like symptoms. 9. He wrote a four-volume work, " Mammalian Protein Metabolism " ( Academic Press, 1964-70 ). 10. The liver is responsible for the mainstay of protein metabolism , synthesis as well as degradation.
