For example, the activity of phospholipase A1/A2 (PLA1/2), which can generate free FAs, and 2‐acyl lysophospholipid or 1‐acyl lysophospholipid through modifying the sn‐1 and sn‐2 positions of the glycerol moieties of phospholipids, is significantly increased in cancer cells.35 This evidence concerns the gene LIPG and cancer.
