Preparation
Diphytanoyl Derivatives of phosphatidylcholine have been useful
in "planer lipid membrane" research. Avanti has supplied
these lipids for several years. Now we are offering the diphytanoyl
phospholipid with various polar head groups. This will provide several
different hydrophilic components for your research.
Note
The diphytanoyl phosphatidylcholine does not have a phase transition
from -120°C to +80°C .
