Donaldson, R P; Beevers, H

Phosphatidyl choline and phosphatidyl ethanolamine are the predominant phospholipids of the isolated glyoxysome membrane. These have relatively more saturated fatty acids, palmitic and stearic, than the whole membrane. The major fatty acids of the lipids in the membrane are linoleic (47%), palmitic (22%), oleic (15%), stearic (9%), and linolenic (4%). The largest proportion of linoleic acid is associated with neutral lipid. This accounts for as much as 30% of the total fatty acid in the membrane. Unlike the storage triglyceride of castor bean this neutral lipid contains no detectable ricinoleic acid. Comparative data for the lipid composition of other membrane fractions from castor bean endosperm will be presented.
