Metabolite Identification
Common NameO-Phosphoethanolamine
DescriptionO-Phosphoethanolamine, also known as colamine phosphoric acid or ethanolamine phosphate, belongs to the class of organic compounds known as phosphoethanolamines. Phosphoethanolamines are compounds containing a phosphate linked to the second carbon of an ethanolamine. O-Phosphoethanolamine exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule. O-Phosphoethanolamine exists in all living species, ranging from bacteria to humans. O-Phosphoethanolamine is a potentially toxic compound.
