Displaying 1 results of Phosphogluconolactone Stable Isotopes Phosphogluconolactone stable isotopes are non-radioactive forms of phosphogluconolactone, a molecule involved in the metabolism of glucose in the body. They are often used in research to track the movement and transformation of this molecule within cells and tissues. These isotopes are chemically identical to the naturally occurring form of the molecule, but have a different number of neutrons in the nucleus, allowing them to be easily distinguished and tracked.
