代谢
氨N 13在肝脏经历五个酶步骤的代谢,生成尿素N 13(主要的循环代谢物)。它还通过骨骼肌、肝脏、大脑、心肌和其他器官中的谷氨酰胺合成代谢成谷氨酰胺N 13(组织中的主要代谢物)。氨N 13的其他代谢物包括少量以谷氨酸N 13或天冬氨酸N 13形式的N 13氨基酸阴离子(酸性氨基酸)。
Ammonia N 13 undergoes a five-enzyme step metabolism in the liver to yield urea N 13 (the main circulating metabolite). It is also metabolized to glutamine N 13 (the main metabolite in tissues) by glutamine synthesis in the skeletal muscles, liver, brain, myocardium, and other organs. Other metabolites of ammonia N 13 include small amounts of N 13 amino acid anions (acidic amino acids) in the forms of glutamate N 13 or aspartate N 13.
