[Application of stable isotopes in the study of whole-body protein metabolism].
Stable isotopes are non-radioactive, so they are safe and suitable for the study of human nutrition. In this paper, the principle and main methods of stable isotopic technique in the study of whole-body protein metabolism were introduced. Meanwhile, the advantages and disadvantages of different methods were discussed and the splanchnic metabolism of labeled amino acids was analyzed.
