Displaying 7 results of Phosphatidylcholine Stable Isotopes Phosphatidylcholine stable isotopes are a set of stable isotopes that are used in research to study the metabolic pathways of phosphatidylcholine, a major phospholipid in cell membranes and surfactants. These isotopes are labeled with stable isotopes such as carbon-13, nitrogen-15, and deuterium, which do not decay over time and can be detected using mass spectrometry. The use of stable isotopes allows researchers to track the movement of phosphatidylcholine within cells and tissues, and to study its role in various biological processes.
