Retinol-d4（Cat No.:S000547） is a specialized form of retinol, a precursor of vitamin A essential for vision, skin health, and immune function. The “d4” designation indicates that four hydrogen atoms in the retinol molecule are replaced with deuterium, a stable isotope of hydrogen. This isotopic substitution enables precise tracking of retinol metabolism and its distribution in biological systems using advanced analytical techniques like mass spectrometry. Retinol-d4 serves as a valuable tool in pharmacokinetic studies, aiding in elucidating vitamin A metabolism, understanding its bioavailability, and investigating its role in various physiological processes and health conditions, including vision disorders and skin diseases.
