This text provides a brief overview of the principles of enzymatic lipid co
nversion and some recent advances in the enzymatic conversion of glyceropho
spholipids and galactolipids. Lipases and phospholipases are used to exchan
ge fatty acids or the polar group in the lipids. The reactions can be carri
ed out either as hydrolysis-esterification sequences or as one-step transfe
rase reactions. The scope and limitations of the different methods are disc
ussed. (C) 2001 Elsevier Science B.V. All rights reserved.
