Concentration of free amino acids in the plasma, erythrocytes and the liver of cattle, sheep and rabbits was different in various species. The differences concerned mainly glutamine, glutamic acid, proline, alanine, glycine. The participation of endogenic amino acids in gluconeogenesis and the nitrogen recycle was discussed considering the characteristics of their metabolism in ruminants.
牛、羊和兔血浆、红细胞及肝脏中游离氨基酸的浓度在不同物种间存在差异。这些差异主要涉及谷氨酰胺、谷氨酸、脯氨酸、丙氨酸和甘氨酸。结合反刍动物体内这些氨基酸的代谢特点,探讨了内源性氨基酸在糖异生和氮循环中的作用。
