Triglyceride identification increased in normal breast tissue (850–1000 m/z)

m/z	Lipid identification	Ion
865.70	TG (50:2)	[M + Cl]-
891.72	TG (52:3)	[M + Cl]-
893.73	TG (52:2)	[M + Cl]-
917.73	TG (54:4)	[M + Cl]-
919.75	TG (54:3)	[M + Cl]-
921.76	TG (54:2)	[M + Cl]-

Possible triglyceride species identified in the mass spectrometry spectra of m/z values that are significantly lower in tumour tissue. Triglycerides are denoted as TG (C:N) where C corresponds to the sum of the carbon atoms in the three fatty acid chains and N corresponds to the sum of the double bonds in the fatty acid chains
