The vitamin does not distribute randomly throughout phospholipid bilayers but forms complexes of defined stoichiometry which coexist with bilayers of pure phospholipid alpha-Tocopherol preferentially forms complexes with phosphatidylethanolamines rather than phosphatidylcholines, and such complexes more readily form nonlamellar structures.
When specific membrane fractions, such as phosphatidylethanolamines and phosphatidylcholines, were examined, however, a decrease in both AA and DHA was observed (34, 35).
Increased plasma homocysteine and S-adenosylhomocysteine and decreased methionine is associated with altered phosphatidylcholine and phosphatidylethanolamine in cystic fibrosis.
