Common NameO-Phosphoethanolamine
DescriptionO-Phosphoethanolamine, also known as colamine phosphoric acid or ethanolamine O-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 is a very strong basic compound (based on its pKa). O-Phosphoethanolamine exists in all living species, ranging from bacteria to humans. Within humans, O-phosphoethanolamine participates in a number of enzymatic reactions. In particular, O-phosphoethanolamine and palmitaldehyde can be biosynthesized from sphinganine 1-phosphate; which is catalyzed by the enzyme sphingosine-1-phosphate lyase 1. In addition, O-phosphoethanolamine and palmitaldehyde can be biosynthesized from sphingosine 1-phosphate; which is catalyzed by the enzyme sphingosine-1-phosphate lyase 1. In humans, O-phosphoethanolamine is involved in globoid cell leukodystrophy. Outside of the human body, O-Phosphoethanolamine has been detected, but not quantified in, several different foods, such as lambsquarters, nutmegs, yellow wax beans, dandelions, and cloud ear fungus. This could make O-phosphoethanolamine a potential biomarker for the consumption of these foods. The ethanolamine mono-ester of phosphoric acid, and a metabolite of phospholipid metabolism. O-Phosphoethanolamine is a potentially toxic compound. O-Phosphoethanolamine is expected to be in Cannabis as all living plants are known to produce and metabolize it.
