However, enzymes show a lower catalytic efficiency (up to three or four orders of magnitude) when employed in organic solvents rather than in aqueous buffer. It is evident that such behavior represents an

The high selectivity and mild reaction con- tions associated with enzymatic transformations have made this approach an attractive alternative in the synthesis of complex bioactive compounds, which are often difficult to o

le attention has been given to the study of glyceride lipases in brain. Brain, in comparison to other organs, contains smaller quantities of neutral glycerides; amounts of triacylglycerol from whole rat brain have been established at 0.15–0.17 umol/g tissue (1). Numerous observations demonstrate tha
