Displaying 1 results of Pantothenic Acid Stable Isotopes Pantothenic acid stable isotopes are non-radioactive forms of the essential B-vitamin, pantothenic acid. These isotopes have the same chemical properties as the naturally occurring pantothenic acid, but with a slightly different atomic mass. They are used in research studies to track the metabolism of pantothenic acid and its derivatives in the body, as well as to study the absorption and bioavailability of pantothenic acid in different foods and supplements. Pantothenic acid stable isotopes are also used in quality control procedures for dietary supplements and fortified foods to ensure accurate labeling and dosing.
