Major fragment ions produced from the CID of triheptadecanoin m/z 855 [MLi]+: the C17 : 0 acylium ion at m/z 253 [C17H33O]+, the lithium adduct of heptadecanoic acid at m/z 277 [C17H34O2Li]+, the neutral loss of heptadecanoic acid, then the neutral loss of a C17 : 1 α,β-unsaturated fatty acid, to give the m/z 317 product ion [MLi – C17H34O2 – C17H32O2]+, the parent ion minus lithiated heptadecanoate at m/z 579 [MLi – C17H33O2Li]+ and the parent ion minus the neutral loss of heptadecanoic acid at m/z 585 [MLi – C17H34O2]+.
