Isotopomer

Isotopomers have applications in areas including nuclear magnetic resonance spectroscopy, reaction kinetics, and biochemistry.

The rare case where two adjacent carbon atoms in a single structure are both 13C causes a detectable coupling effect between them as well as signals for each one itself.

This kinetic isotope effect can be used to study reaction mechanisms by analyzing how the differently massed atom is involved in the process.

Monocots, such as rice and oats, differ from dicots, such as potatoes and tree fruits, in the relative amounts of 12CO2 and 13CO2 that they incorporate into their tissues as products of photosynthesis.

A cumomer is a set of isotopomers sharing similar properties and is a concept that relates to metabolic flux analysis.
