Oral cavity discrimination of vapor-phase long-chain 18-carbon fatty acids.

Shared retronasal identifications of vapor-phase 18-carbon fatty acids.

The long-chain 18-carbon fatty acids linoleic, oleic, and stearic acids, retronasally in vapor phase, are discriminated from blanks and each other. However, ability to linguistically identify them was unknown. To explore this, a Focus Group and then Check-All-That-Apply measures gave 9 identifiers for the 3 fatty acids plus phenylethyl alcohol (PEA) and geraniol. Next, participants selected 1 o...

Inhibition of Thermophilic Anaerobic Digestion of Waste Food by Long Chain Fatty Acids and Propionate

Lipid-degrading enzyme activities associated with distribution and degradation of fatty acids in the mixing zone of Altamaha estuarine sediments

To examine the relationship between lipid-degrading enzyme activities and lipid composition in estuarine sediments, lipase activities and fatty acids in surface sediments at di€erent stations along the Altamaha River were determined during a high discharge period. Freshwater sandy sediments from upstream stations were characterized by low organic carbon and low lipid contents. Sediments from th...

A condensing enzyme from the seeds of Lesquerella fendleri that specifically elongates hydroxy fatty acids.

Lesquerella fendleri seed oil contains up to 60% hydroxy fatty acids, nearly all of which is the 20-carbon hydroxy fatty acid lesquerolic acid (D-14-hydroxyeicos-cis-11-enoic acid). Previous work suggested that lesquerolic acid in L. fendleri was formed by the elongation of the 18-carbon hydroxy fatty acid, ricinoleic acid. To identify a gene encoding the enzyme involved in hydroxy fatty acid e...

Effects of enriched Artemia with n–3 long-chain polyunsaturated fatty acids on growth performance, stress resistance and fatty acid profile of Litopenaeus vannamei postlarvae

A 15-day study was conducted to evaluate the effects of Artemia metanauplii enriched with two commercial supplements (Easy DHA-Selco and S. presso) which contained high levels of n–3 long chain polyunsaturated fatty acids (n–3 LC-PUFA) on growth performance, stress resistance and fatty acid profile of Litopenaeus vannamei post larvae (PL). In this regard, PL ...
