The present investigation presents results of studying free amino acids of peripheral plasma in cosmonauts who made space flights of different duration onboard the spacecraft Soyuz-12, Soyuz-16 and the orbital station Salyut-4. The study showed changes in the content of free amino acids which varied for different amino acids. Most pronounced changes were found in the content of glutamic and aspartic acids, sulfur-containing amino acids and arginine.
本次调查展示了对搭乘“联盟12号”“联盟16号”宇宙飞船以及“礼炮4号”轨道空间站进行不同时长太空飞行的宇航员外周血浆中游离氨基酸的研究结果。研究表明，游离氨基酸的含量发生了变化，不同氨基酸的变化情况各异。谷氨酸、天冬氨酸、含硫氨基酸和精氨酸的含量变化最为显著。
