Molecular structures of short CL species in acb1 cells as resolved by MS/MS analysis of the peak of highest intensity in the C52–C56 clusters

CL species	Parent m/z	Most abundant acyl chainsa	Possible acyl chain compositionsb
C52:2	589.37	C10:0 and C16:1	(C10:0)2(C16:1)2
C54:2	603.38	C10:0, C12:0 and C16:1	(C10:0)(C12:0)(C16:1)2
C56:2	617.40	C10:0, C12:0, C16:1 and C18:1	(C10:0)(C12:0)(C16:1)(C18:1) and (C12:0)2(C16:1)2

^a Based on peak heights.

^bAcyl chain compositions were determined, based on the acyl chains that were identified and the mass and number of double bonds of each species.
