Metabolite Identification
Common NameTG(16:0/16:0/16:0)[iso]
DescriptionTG(16:0/16:0/16:0), also known as tripalmitoylglycerol or glyceryl tripalmitate, 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(16:0/16:0/16:0) is considered to be a triradylglycerol lipid molecule. TG(16:0/16:0/16:0) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. TG(16:0/16:0/16:0) exists in all eukaryotes, ranging from yeast to humans. In cattle, TG(16:0/16:0/16:0) is involved in the metabolic pathway called the glycerolipid metabolism pathway.

Enzyme Details
2. Diacylglycerol O-acyltransferase 1
General function:
Not Available
Specific function:
Catalyzes the terminal and only committed step in triacylglycerol synthesis by using diacylglycerol and fatty acyl CoA as substrates. In contrast to DGAT2 it is not essential for survival. May be involved in VLDL (very low density lipoprotein) assembly. Functions as the major acyl-CoA retinol acyltransferase (ARAT) in the skin, where it acts to maintain retinoid homeostasis and prevent retinoid toxicity leading to skin and hair disorders. In liver, plays a role in esterifying exogenous fatty acids to glycerol.
