Metabolite Identification
Common NamePhytosphingosine
DescriptionPhytosphingosine, also known as SP(t18:0), belongs to the class of organic compounds known as 1,3-aminoalcohols. These are organic compounds containing an alkyl chain with an amine group bound to the C1 atom and an alcohol group bound to the C3 atom. Thus, phytosphingosine is considered to be a sphingoid base lipid molecule. Phytosphingosine is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Phytosphingosine exists in all eukaryotes, ranging from yeast to humans.
