Three different tests on houseflies (Musca domestica L.) revealed that both pheromone-free pseudoflies and male partner flies exhibit in the presence of mixtures of long-chain (Z)-9-alkenes or pure (Z)-9-tricosene enhanced releasing effects for two optical cues, which stimulate male houseflies to mating strikes and houseflies of both sexes to aggregation.
The environmental conditions prevailing during growth of plant tissue cultures affect the concentration of certain lipid classes and the fatty acid patterns of the total lipids. Irrespective of whether the cultures are grown under continuous illumination or in the dark, aerated cultures contain larger proportions of sterols, steryl esters, steryl glycosides… (More)
The chromatographic behavior of some minor components of natural lipids was studied using layers of magnesium oxide and of commercial adsorbents containing magnesium oxide. The lipids investigated included wax esters, cholesteryl esters, diester waxes, and esters, ethers and ether-esters of ethanediol and glycerol. Pronounced differences were found in the… (More)
Heterotrophically grown cell suspension cultures of soya (Glycine max L.) were incubated with two different mixed substrates consisting of positional isomers of either cis-[1-14C]octadecenoic acids (Δ8 to δ15) or trans-[1-14C]octadecenoic acids (Δ8 to Δ16), each with known composition. With both substrates, about one-fourth of the radioactivity supplied was… (More)
The lipids of Chlorella fusca are composed of the ester lipids typical of photosynthetically active cells. In addition, there occurs a class of less common ether lipids, the biologically active 1(3),2-diacylglycero-3(1)-O-4'-(N,N,N- trimethyl)homoserines, at a level of about 1.3% of total lipids. The acyl moieties of the total lipids include saturated as… (More)
Resembling the lipids in the leaves and other green organs of intact plants, the lipids in photoautotrophic cell cultures of Chenopodium rubrum were found to contain high proportions of monogalactosyldiacylglycerols and digalactosyldiacylglycerols, as well as fair amounts of sulfoquinovosyldiacylglycerols and diacylglycerophosphoglycerols. Conversely, the… (More)
Long-chain alkyl and alkenyl bromides are obtained in quantitative yields by the reaction of methane-sulfonates with anhydrous magnesium bromide in absolute ether; cis-trans isomerization of double bonds does not occur.
The major alkoxylipids of human heart and aorta are alkyl and alk-1-enyl diacyl glycerols, alkyl acyl and alk-1-enyl acyl glycerophosphoryl cholines, and the corresponding glycerophosphoryl ethanolamines. There are no pronounced differences in the composition of corresponding classes of alkoxylipids from heart, aorta, and other human tissues previously… (More)
