DescriptionTG(15:0/20:0/22:0) belongs to the family of triradyglycerols, which are glycerolipids lipids containing a common glycerol backbone to which at least one fatty acyl group is esterified. Their general formula is [R1]OCC(CO[R2])O[R3]. TG(15:0/20:0/22:0) is made up of one pentadecanoyl(R1), one eicosanoyl(R2), and one docosanoyl(R3).
