Metabolite Identification
Common NameTG(18:0/18:0/18:0)
DescriptionTG(18:0/18:0/18:0), also known as stearin or glyceryl tristearate, 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. Thus, TG(18:0/18:0/18:0) is considered to be a triradylglycerol lipid molecule. TG(18:0/18:0/18:0) exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. TG(18:0/18:0/18:0) exists in all eukaryotes, ranging from yeast to humans. TG(18:0/18:0/18:0) can be biosynthesized from DG(18:0/18:0/0:0) and stearoyl-CoA through its interaction with the enzyme diacylglycerol O-acyltransferase. In cattle, TG(18:0/18:0/18:0) is involved in the metabolic pathway called de novo triacylglycerol biosynthesis TG(18:0/18:0/18:0) pathway.
