Isotopologs

Isotopologs are a class of molecules that are structural isomers of each other, meaning they have the same molecular formula but differ in the arrangement of their atoms. The term "isotopologs" specifically refers to isotopomers that are structural isomers. Isotopomers are molecules that contain the same number of atoms of each element but differ in the isotopic composition of one or more atoms. Isotopologs, therefore, are isotopomers that have different structural arrangements of their atoms.

The study of isotopologs is important in various fields of chemistry and biology. In chemistry, isotopologs can provide insights into reaction mechanisms and stereochemistry. In biology, isotopologs can be used to study metabolic pathways and enzyme kinetics. The term "isotopologs" was first introduced in the scientific literature in the early 2000s, and since then, it has been used to describe a wide range of molecules in various scientific disciplines.

Isotopologs can be synthesized using various methods, including isotopic labeling and isotopic exchange reactions. The properties of isotopologs can be studied using techniques such as mass spectrometry, nuclear magnetic resonance spectroscopy, and infrared spectroscopy. The study of isotopologs continues to be an active area of research, with new isotopologs being discovered and characterized each year.
