The Lipid Calculator has been upgraded to a Progressive Web App (PWA), making it faster, more reliable, and easier to use across desktop and mobile devices. Calculate accurate monoisotopic molecular masses and positive/negative electrospray ion m/z values for a wide range of lipid classes, with direct searching of the LIPID MAPS Structure Database using LIPID MAPS abbreviations.
Originally developed by Brendan J. Murphy and Robert C. Murphy, the tool continues to provide trusted support for lipidomics research.
