Metabolite Identification
Common NameTG(18:0/16:0/18:0)
DescriptionTG(18:0/16:0/18:0), also known as triacylglycerol(52:0) or 2-palmitodistearin, belongs to the class of organic compounds known as triacylglycerols. These are glycerides consisting of three fatty acid chains covalently bonded to a glycerol molecule through ester linkages. TG(18:0/16:0/18:0) exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule.
