Lipase-catalyzed reactions in organic media: competition and applications. 1987

H Deleuze, and G Langrand, and H Millet, and J Baratti, and G Buono, and C Triantaphylides

Lipases (triacylglycerol acylhydrolase, EC 3.1.1.3) have been used in organic media for the catalysis of reactions such as hydrolysis, esterification and transesterification. In these conditions it was confirmed that all reactions proceed through an acyl enzyme intermediate in two successive steps: acyl enzyme formation and solvolysis. The competition between two acyl acceptors (acyl donors) for reaction with a donor (acceptor) is described for the first time. A kinetic model is proposed using a competitive factor which is in good accordance with experimental results. The model was used successfully for the prediction of alcohol (acid) separations and resolutions by lipases.

UI MeSH Term Description Entries
D007700 Kinetics The rate dynamics in chemical or physical systems.
D008049 Lipase An enzyme of the hydrolase class that catalyzes the reaction of triacylglycerol and water to yield diacylglycerol and a fatty acid anion. It is produced by glands on the tongue and by the pancreas and initiates the digestion of dietary fats. (From Dorland, 27th ed) EC 3.1.1.3.

D009089 Mucor A genus of zygomycetous fungi of the family Mucoraceae, order Mucorales. It is primarily saprophytic, but may cause MUCORMYCOSIS in man from spores germinating in the lungs. Mucors
D002087 Butyrates Derivatives of BUTYRIC ACID. Included under this heading are a broad variety of acid forms, salts, esters, and amides that contain the carboxypropane structure. Butyrate,n-Butyrate,Butanoic Acids,Butyric Acids,Acids, Butanoic,Acids, Butyric,n Butyrate
D002175 Candida A genus of yeast-like mitosporic Saccharomycetales fungi characterized by producing yeast cells, mycelia, pseudomycelia, and blastophores. It is commonly part of the normal flora of the skin, mouth, intestinal tract, and vagina, but can cause a variety of infections, including CANDIDIASIS; ONYCHOMYCOSIS; VULVOVAGINAL CANDIDIASIS; and CANDIDIASIS, ORAL (THRUSH).

D004951 Esterification The process of converting an acid into an alkyl or aryl derivative. Most frequently the process consists of the reaction of an acid with an alcohol in the presence of a trace of mineral acid as catalyst or the reaction of an acyl chloride with an alcohol. Esterification can also be accomplished by enzymatic processes. Esterifications
D004952 Esters Compounds derived from organic or inorganic acids in which at least one hydroxyl group is replaced by an –O-alkyl or another organic group. They can be represented by the structure formula RCOOR’ and are usually formed by the reaction between an acid and an alcohol with elimination of water. Ester
D006868 Hydrolysis The process of cleaving a chemical compound by the addition of a molecule of water.
D000438 Alcohols Alkyl compounds containing a hydroxyl group. They are classified according to relation of the carbon atom: primary alcohols, R-CH2OH; secondary alcohols, R2-CHOH; tertiary alcohols, R3-COH. (From Grant & Hackh's Chemical Dictionary, 5th ed)
