Chapter 13—Probes for Lipids and Membranes (3.9 MB) The probes in this section and in Sphingolipids, Steroids, Lipopolysaccharides and Related Probes—Section 13.3 bear some structural resemblance to natural lipids. Included in this section are fluorescent fatty...
Pseudomonas aeruginosa 42A2 is known to produce two hydroxy-fatty acids, 10(S)-hydroxy-8(E)-octadecenoic and 7,10(S,S)-dihydroxy-8(E)-octadecenoic acids, when cultivated in a mineral medium using oleic acid as a single carbon source. These compounds were purified, 91 and 96 % respectivel...
Various protraction mechanisms are enabled by the specific characteristics and positions of the attached fatty acid. Furthermore, the technology can ensure a long half-life following oral administration of peptide drugs, can alter the distribution of peptides and may hold potential for tissue targeting...
Semenkovich, in Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2012 Abstract Fatty acid synthase (FAS) catalyzes the de novo synthesis of fatty acids. In the liver, FAS has long been categorized as a housekeeping protein, producing fat for storage of energy when...
.49This mixture is normally stripped by overhead distillation of most of the monomer acid. Most of the residue (calledundistilled dimer) is sold as such, but some is further distilled using a wiped-film evaporator to produce adistilled dimer acidand a residue of mainly trimer acid. The ...
LIPIDSMESOGASTROPODNIGERIAThe application of a combined solid phase extraction (SPE)/clean-up procedure to the isolation of a purified fraction containing all the monomeric cyclic fatty acid methyl esters is described. Extraction of the nonpolar lipid components from nonurea-adducting (NUA) filtrates...
Biosynthesis and degradation of fatty acids and membrane lipids. ATP and reduction equivalents are colored red if consumed and green if gained. Enzymes are colored blue. FAB, fatty acid biosynthesis; FAD, fatty acid degradation. Full size image AccABCD: acetyl-CoA carboxylase Acetyl-CoA carboxylase...
honeybee queen produces pheromones such as 9-hydroxy-2-decenoic acid, and other acids functionalized at the penultimate (w-1) position (Plettner E et al., Science 1996, 271, 1851). Several parent molecules have been described in the royal jelly (Noda N et al., Lipids 2005, 40, 833)....
When cis- and trans-form of 18:1 in l-elaidate-2,3-dioleate were compared for lipolysis, lipase from G. candidum preferentially hydrolyzed the cis-form to free fatty acid (Senanayake and Shahidi, 2002). Among the currently available methods for modifying lipids, lipase-catalyzed reactions ...
When autoxidized fatty esters and purified fatty hydroperoxides were decomposed in the absence of oxygen at 210°C., the principal reaction was dimerization of the fatty acid chains with elimination of the hydroperoxide groups. Dimers isolated by molecular distillation (60 to 90% of the polymer) ...
