Cinnamyl acetate synthesis by lipase-catalyzed transesterification in a solvent-free system.

abstract：:Various approaches for removal of high-abundance components in body fluids are currently available. While most methods are constructed for plasma depletion, there is a need for body-fluid-specific strategies. The aim of the present study was to design an affinity matrix suitable for the depletion of high-abundance pro...
