O-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. It is a very strong basic compound (based on its pKa) and exists in all living species, ranging from bacteria to humans. Within yeast, it participates in a number of enzymatic reactions.
In particular, ethanolamine O-phosphate can be biosynthesized from ethanolamine; which is mediated by the enzyme choline/ethanolamine kinase. In addition, cytidine triphosphate and it also can be converted into CDP-ethanolamine through the action of the enzyme ethanolamine-phosphate cytidylyltransferase.
In yeast, the product is involved in the metabolic pathway called phosphatidylcholine biosynthesis pathway and it is a potentially toxic compound.
