When FFA is lower than about 5%, the reaction can be catalyzed with an alkali catalyst; but an additional catalyst is required to compensate for the catalyst lost in soap formation. The soap created during the reaction is either removed with the glycerol or is washed out during the water was...

Typically, alpha-2,3-sialyllactose is used as the sialic acid donor in trans-sialidase catalyzed reaction. However, due to limitations such as reversibility and cost, alternative sialic acid donors are needed. Here we show that fetuin, a glycoprotein containing abundant sialic acids at the ends ...
(ALA) was predominantly catalyzed by the bifunctional ∆12/∆15 Fad2. FAD4 was found to encode a trifunctional ∆9/∆12/∆15 FAD, playing important roles in lipid and biomass production as well as stress resistance. Furthermore, an abundantly transcribedOLE1-related gene,OLE2encoding ...
