The human colorectal adenocarcinoma sample was excised during a surgical operation performed at the Imperial College Healthcare NHS Trust. The sample and procedures were carried out in accordance with ethical approval (14/EE/0024).

DG(21:0/20:3(5Z,8Z,11Z)-O(14R,15S)/0:0) belongs to the family of Diacylglycerols. These are glycerolipids lipids containing a common glycerol backbone to which at least one fatty acyl group is esterified. DG(21:0/20:3(5Z,8Z,11Z)-O(14R,15S)/0:0) is also a substrate of diacylglycerol kinase. It is involved in the phospholipid metabolic pathway.
