1111-72-4 - Reference Information
| stable isotope of carbon | carbon 13 is one of the stable isotopes of carbon, accounting for about 1.109% of the Earth's natural carbon. Carbon -13(13C)(13 written in the upper left corner of C) is an isotope of carbon, its nucleus contains 6 protons and 7 neutrons (one more than the common carbon 12 neutrons), the nucleus has 6 electrons outside the nucleus, neutral. |
| Use | because plants absorb carbon dioxide from the air, CO2 can also be labeled with the isotopic gas 13CO2. Biologists use the isotope symbol isotope gas carbon dioxide-13C to feed algae, bacteria and other microorganisms, and use nuclear magnetic resonance to study their metabolic processes, allowing algae to grow in a pure 13CO2 atmosphere, the algae can be uniformly 13C-labeled, so that various amino acids, proteins, fats, sugars and DNA can be extracted from the 13C-labeled organic matter. The amount of extracted components is dramatically added to algae or bacteria-produced microorganisms Fed labeled carbon 13 carbon dioxide. Carbon dioxide-13C is carbon 13 labeled carbon dioxide isotope gas, it is often used as a tracer for the study of organic chemical reactions, has a wide range of applications. |
