The acylolytic cleavage of glycerol methylene acetals with fatty acids provides a new synthetic strategy that leads to pure mixed 1,2-diglycerides.

A true convert: The carboxylesterase enzyme R.34 (see picture) can be converted into a triacylglycerol lipase without modification of the shape, size, or hydrophobicity of the substrate binding site. The substitution of Asn33 by Asp results in a salt bridge between the Asp33 and Arg49, which causes a distortion of the enzyme structure that makes the catalytic site more accessible to larger substrates but also more labile.

A host-recognizing kairomone responsible for the stinging behavior of the parasitic wasp, Dinarmus basalis, was studied. Fresh azuki beans coated with an acetone extract of the azuki beans, from which both emerged wasps and their host weevils were removed, elicited stinging behavior from female wasps. The kairomone is a mixture of saturated hydrocarbons and diacylglycerols, both of which are required for activity. The kairomone is composed of normal and methyl-branched hydrocarbons with carbon numbers ranging from 25 to 35, most of which are known as the hydrocarbon constituents of an oviposition-marking pheromone of the host azuki bean weevils, Callosobruchus chinensis. This indicates that D. basalis utilizes the oviposition-marking pheromone of its host weevils as a host-recognizing kairomone.
