Displaying 3 results of Linolenic Acid Stable Isotopes Linolenic acid stable isotopes are isotopes of the essential fatty acid linolenic acid that have a stable atomic configuration. These isotopes are used in research studies to trace and quantify the metabolic fate of linolenic acid in biological systems. By using stable isotopes, researchers can accurately measure the uptake, distribution, and utilization of linolenic acid in the body, which can provide valuable insights into the role of this important fatty acid in human health and disease.
