Egg Production Constrains Chemical Defenses in a Neotropical Arachnid. [PDF]
PLoS ONE, 2015 Female investment in large eggs increases the demand for fatty acids, which are allocated for yolk production. Since the biosynthetic pathway leading to fatty acids uses the same precursors used in the formation of polyketides, allocation trade-offs are ...

Prevention of Undesirable Isomerization during Olefin Metathesis [PDF]
, 2005 1,4-Benzoquinones have been found to prevent olefin isomerization of a number of allylic ethers and long-chain aliphatic alkenes during ruthenium-catalyzed olefin metathesis reactions. Electron-deficient benzoquinones are the most effective additives for
