DescriptionTG(14:0/16:0/22:0) 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(14:0/16:0/22:0) is made up of one tetradecanoyl(R1), one hexadecanoyl(R2), and one docosanoyl(R3).
