1. In nature, many FFAs have ethanolamine as the amine component. 2. Piroctone olamine is the ethanolamine salt of the hydroxamic acid derivative piroctone. 3. Treatment with ethanolamine ends up making an aminoetylborinate. 4. Specifically, it is a structural isomer of 2-aminoethanol ( ethanolamine ). 5. This condenses with membrane-bound ethanolamine to form a Schiff's base. 6. Ethanolamine is a colorless, viscous liquid with an odor reminiscent to that of ammonia.7. Ethanolamine and choline are major membrane phospholipids, in the form of glycerophosphoethanolamine and glycerophosphocholine.8. Phosphocholine is then activated by the addition of choline / ethanolamine phosphotransferase ( CEPT ). 9. This forms ethanolamine phosphate and hexadecenal. 10. The table below lists experimentally determined spontaneous curvatures for different lipids in DOPE ( dioleyl phosphatidyl ethanolamine ).
