Enzymatic phenethyl octanoate synthesis: lipase selection and reaction optimization by response surface methodology
* corresponding author. e-mail: [email protected] Phenethyl octanoate (PEO) is a natural flavour compound found in rum, spirits and wine. Six commercial and non-commercial lipase preparations were screened for 2-phenethyl octanoate synthesis activity, the most active enzymes were Lipozyme® RM IM and Palatase® 20000 L (immobilized and soluble Rhizomucor miehei lipases). Three substrates a...
متن کاملThe oxidation of octanoate by liver homogenates from leucemic mice.
We have begun an investigation of the level of enzymatic activity in tissues which have been in filtrated by malignant cells. Two preliminary re ports of this work have appeared (1, @). We are presenting herewith results of studies of fatty acid oxidase activity which have been carried out on C58 mouse liver homogenates according to Lehn inger (3, 4). In addition, results of orienting ex perime...

متن کاملModulation of pyruvate dehydrogenase kinase activity in cultured hepatocytes by glucagon and n-octanoate.
The activity of pyruvate dehydrogenase kinase in extracts of mitochondria from rat hepatocytes cultured for 21 h in medium 199 was increased 2.5-fold by the presence of 55 nM-glucagon and 1 mM-sodium n-octanoate in the culture medium. The change was comparable with that induced in vivo by 48 h starvation. The potential contribution of branched-chain complex to estimates of PDH-complex activity ...
متن کاملMicrowave Assisted Synthesis of N-Benzylenaminones Catalyzed by Chloroacetic acid
Benzylaminoalkenones and benzylaminoalkenoates 3 were synthesized from reaction of benzylamine with corresponding 1,3-diketones and 1,3-ketoesters in the presence of catalytic amount of chloroacetic acid under microwave radiation. This method offers several advantages including high yield of products, recyclable of the catalyst and easy experimental work-up procedure.
