The hypothesis that the Δ9 desaturase of Chlorella vulgaris might operate by a synchronous mechanism has been tested using a kinetic isotope effect (KIE) approach. Thus the intermolecular primary deuterium KIE on the individual C–H bond cleavage s

The whole-cell Chlorella vulgaris (211/8 K) system allows us to use thiastearate methyl esters as a mechanistic probe of the Δ12-desaturation process. The 6-, 7-, 12- and 13-thiastearates are converted intracellularly to the corresponding Δ9-desatu

The synthesis of three acids was achieved using the Wittig reaction in order to study their in vivo influence on the Δ12-desaturase of Chlorella sorokiniana. It was shown that the introduction of two methyls near the double bond prevent the desatura

The synthetic analogue of oleic acid, 13-thiaoleic acid, was readily oxidised to the corresponding S -oxide by the algae, Chlorella vulgaris . Among the thiaoleic acids tested, it was the only one that decreased the in vivo oleoyl desaturation rate o

The well known drugs (S)-Ibuprofen and (S)-Naproxen were used as NMR shift reagents for the stereochemical analysis of alkylsulfoxides. It was shown that (S)-Naproxen could be worthwhile substituted to (S)-MPA or (S)-2-NMA for the stereochemical anal

S-13 thiaoleic acid was transformed to the corresponding sulfoxide by Chlorella vulgaris (211/8k) and the likely intervention of the cytoplasmic oleoyl desaturase in this biotransformation was studied by the time-course incorporation and the transfor

Starting from gold chips, we have tailor-made three surfaces by the self-assembly monolayer technique: one entirely hydrophobic, one hydrophobic with dispersed carboxyl groups, and one hydrophilic, containing hydroxyl groups. Rhizomucor miehei lipase

The valuable nutraceutical gamma-linolenic acid (GLA, (6Z,9Z,12Z)-octadecatrienoic acid) is biosynthesized by a series of regio- and stereoselective dehydrogenation reactions that are catalyzed by a set of enzymes known as fatty acid desaturases. As

In a non aerated incubation medium, the oxidation of the tested thiaoleic acids by C. vulgaris was regioselective. Moreover the non oxidised 14-thiaoleic acid had no influence on the endogenous fatty acid pattern whereas the 13-thiaoleic acid, readil
