Chemical Properties
O-PHOSPHORYLETHANOLAMINE is white powder
Uses
O-Phosphorylethanolamine has been used:
- in LHC-8 medium as a supplement in culturing the transformed human liver epithelial (THLE)-2 and THLE-3 cells
- in C-reactive protein (CRP) binding sucrose flotation experiment
- to incubate phosphomonoesters with anion-exchange chromatography (AEC) fractions for the detection of phosphatase activity
- to add in the washed beads for the preparation of phosphorylethanolamine (Pet) -conjugated sepharose column for chromatographic purification of mutant CRP
Uses
O-PHOSPHORYLETHANOLAMINEe is used in the synthesis of Sphingomyelin, a type of sphingolipid found in animal cell membrane.
Definition
ChEBI: The ethanolamine mono-ester of phosphoric acid, and a metabolite of phospholipid metabolism. This phosphomonoester shows strong structural similarity to the inhibitory neurotransmitter GABA, and is decreased in post-mortem Alzheimer's disease brain.
Biochem/physiol Actions
Phosphorylethanolamine participates in phospholipid metabolism. Its release can be stimulated occasionally by depolarizing stimuli. Reduction of phosphorylethanolamine levels has been observed in Alzheimer′s and Huntington′s disease.
Purification Methods
Purification by recrystallisation from aqueous EtOH gives a hydrate (m 140-141o). Its solubility in H2O is 17% and 0.003% in MeOH or EtOH at 22o.
