Within the cell glyceryl trimyristate is primarily located in the membrane (predicted from logP) and adiposome. glyceryl trimyristate exists in all eukaryotes ranging from yeast to humans. In humans glyceryl trimyristate is involved in the metabolic disorder called de novo triacylglycerol biosynthesis glyceryl trimyristate pathway.

Sphingosine-1-phosphate (S1P) is an agonist for S1P1-5 receptors and a ligand for GPR3, GPR6, and GPR12. As an intracellular second messenger, it mobilizes Ca2+ and acts as an extracellular ligand for G-protein coupled receptors.
