Calculate the m/z value for a lipid ion of interest by choosing functional groups and ion type from the menu options below.
Structures and isotopic distribution profiles (formula hyperlink) are displayed on the results page along with the exact mass and molecular formula.
Note:Chains containing double bonds and/or functional groups with defined regiochemistry, geometry and stereochemistry are meant to serve as examples
for structure-drawing purposes. In many cases there may be alternative isobaric structures.
