TL;DR: The use of mixtures of miscible solvents (e.g. dimethylsulfoxide and 2-methyl-2-butanol) as a general strategy to acylate enzymatically hydrophilic substrates is proposed and it is observed that decreasing the hydrophobicity of the medium can be substantially enhanced.

TL;DR: The porcine pancreatic lipase adsorbed on Celite was found to be the most effective biocatalyst tested and high activity and excellent selectivity toward the formation of intermediate acylglycerols were achieved.

TL;DR: Lipases from different origins have been immobilized in supports chosen by its different aquaphilicity and used as biocatalysts for the hydrolysis of tributyrin and Maximal yields of dibutyrin were found with the solubleCandida lipase, whereas the highest yield was obtained with the least aquaphylic derivative (Candida-Celite).

TL;DR: Transesterification between ethyl butyrate and glycerol using very different lipase preparations in a two-phase system—no extra solvent added—has been investigated and only monobutyrin was produced in all conditions tested.

TL;DR: Mixtures of 1(3)-monostearin and distearin were prepared by direct esterification of glycerol with stearic acid or transesterification using ethyl stearate as acyl donor in the presence of Candida antarctica lipase using a variety of solvents of differing polarity.
