List of other lipids that may be involved in various types of cancer.

Lipids	Composition	Presence of the Side of Membrane	Cancer Types	Levels	Functions	Ref.
Phosphoinositide	Phosphate group, two fatty acid chain and inositol molecule	Primarily located inner leaflet	Breast, Prostate, Ovarian, Lung, and Gastric	Increased	Signaling for cell proliferation and motility	[363,364,365,366]
Cholesterol	Sterol composed of four hydrocarbon rings, and a hydroxyl group	Primarily located outer leaflet	Most types	Alteration	Controlling membrane structure	[368]
Prostaglandin	Five member ring with fatty acid, arachidonic acid	Primarily located inner leaflet	Most types	Secreted by cancer cells	Angiogenesis, anti-apoptosis, invasion	[369]
lysophosphatidic acid	Contains a glycerol backbone with a phosphoryl group	Primarily located outer leaflet	Ovarian	Increased	Enhanced metastasis	[370,371,372]
sphingosine 1 phosphate	Amphipatic lysophospholipid composed of a sphingoid extended chain and a phosphate molecule.	Primarily located outer leaflet	Most types	Secreted by cancer cells	Angiogenesis	[373,374,375,376]
Ceramides	Contains sphingosine and a fatty acid	Both leaflets	Breast, Prostate, and Ovarian	Decreased level	Cell cycle arrest and apoptosis	[368]
