Interaction of rabbit lipoproteins and red blood cells with liposomes of egg yolk phospholipids.

abstract：:A novel phospholipid containing a chromanol structure at its polar head group was synthesized from egg yolk phosphatidylcholine and 2,5,7,8-tetramethyl-6-hydroxy-2-(hydroxyethyl)chroman by transphosphatidylation catalyzed by phospholipase D from Streptomyces lydicus. The structure of the product synthesized was shown ...
