A method is described for analysing molecular species of glycerophosph
olipids. Diglycerides obtained by phospholipase C-catalysed hydrolysis
of the phospholipid are separated into the diacyl-aikylacyl- and alke
nylacyl-subclasses by HPLC on silicic acid. The molecular species of d
iacylglycerol are separated by HPLC of underivatised diglycerides on a
reverse phase octadecyl-silica column.
