Application of Amino Acid and Nucleic Acid Isotope

Amino acids and nucleic acids are important molecules in organisms, and they both contain isotopes. Among amino acids, the common isotopes include 13C, 15N and 17O. These isotopes can be used to study the processes of protein synthesis, substitution and post-revision. In nucleic acids, the common isotopes include 13C, 14N and 18O. These isotopes can be used to study the processes of DNA replication, transcript and gene expression.

The application of amino acid and nucleic acid isotopes is mainly concentrated in the following aspects:

1. Study protein synthesis and post-revision: the process of protein synthesis and modification can be understood by measuring the isotope content in protein protein. For example, 13C isotopes can be used to study the carbon substitution of amino acids, and 15N isotopes can be used to study the nitrogen substitution of amino acids.

two。 Research generation: isotopes can be used to study the formation of generation routes and products. For example, 13C isotope can be used to study carbohydrate substitution, and 15N isotope can be used to study amino acid substitution.

3. The study of gene tables shows that isotopes can be used to study the transcription and replication processes of RNA and DNA. For example, 13C isotope can be used to study RNA transcript and 14N isotope can be used to study DNA replication.

In general, amino acid and nucleic acid isotopes are very important tools in biological research, and they can help us better understand the biochemical processes and physiological responses in the biological system.
