Synthesis of the naturally occurring cyclopropenoids malvalic and sterculic acids

Synthesis of the naturally occurring cyclopropenoids malvalic and sterculic acids by William David Kray Download PDF EPUB FB2

Sterculic oil contains two unique cyclopropenoic fatty acids, sterculic (55%), and malvalic (10%) acids [11] [12], which inhibit the enzymatic activity of SCD1 [9] [10]. Recently, SCD1, a major. The three cyclopropane fatty acids, identified by comparison with published mass spectra [29] such as malvalic acid, sterculic acid and dihydrosterculic acid accounted for, and %.

Most fatty acids have double bonds in the cis configuration; however, trans double bonds are also found. There are also different positional isomers, conjugated unsaturated, acetylenates, hydroxy, epoxy, and keto fatty acids. Cyclopropenoids, cyclopentenoids, and even fluoro fatty acids add more diversity to the fatty acid species.

SYNTHESIS OF FATTY ACIDS: preferably less than 18%. In an embodiment, the cottonseed oil also contains cyclopropanated fatty acids such as sterculic and malvalic acids, and may contain small amounts of gossypol.

The polynucleotide may encode an enzyme having an amino acid sequence which is the same as a sequence of a naturally occurring. See Meade () for a review on the naturally occurring acetylenic acids.

_indd 10 9/27/ PM Fatty Acid Classification and Nomenclature 11 V. OXYGENATED FATTY ACIDS The naturally occurring oxygenated fatty acids include the hydroxyl, keto, and epoxy groups, of which the hydroxy-substituted acids are most common.

The values (area percent) for fa tty acids as methyl ester were: C (%), C (%), C (%), C (%), C (%), C l (%), C plus C l (1%)> malvalic acid (%), C (%), and sterculic acid (%) Malvalic and sterculic acids were determined as AgNO3-C II3OH derivatives of their methyl.

Biosensors can have applications in proximate analysis and analysis of pesticide residues, naturally occurring toxins and antinutrients, processing changes, microbial contamination and in monitoring enzyme inactivation.

Wagner () has discussed the use of biosensors in food analysis.
