The potential for the preservation of lipids is relatively high since by definition they are hydrophobic and not susceptible to hydrolysis by water, unlike most amino acids and DNA. A wide range of fatty acids, sterols, acylglycerols, and wax esters have been identified in visible surface debris on pottery fragments or as residues absorbed into the permeable ceramic matrix. Isolation of lipids from these matrices is achieved by solvent extraction of powdered samples and analysis is often by the powerful and sensitive technique of combined gas chromatography-mass spectrometry (GC-MS see Section 8.4). This approach has been successfully used for the identification of ancient lipid residues, contributing to the study of artifact... [Pg.23]

In lipidomics, MS can be used either by direct infusion, that is, by the so-called shotgun MS, or in combination with chromatographic separation, typically LC and sometimes also with GC. Both approaches have their own advantages and limitations. Most targeted lipid analyses are performed with liquid chromatography coupled to mass spectrometry (LC-MS), while the use of gas chromatography-mass spectrometry (GC-MS) is utilized only for the analysis of fatty acids and some steroids. In addition, surface analysis by MS has been applied in lipid analysis of intact tissues. [Pg.380]

Virtually all volatile aromatic and flavorsome lipid-derived compounds are analyzed using gas chromatography-mass spectrometry (GC-MS). The components of interest are isolated initially, concentrated, then injected onto a suitable capillary column and detected using a mass spectrometer. [Pg.687]

The development of objectionable flavor compounds by oxidation has significant detrimental effects on consumer acceptability of edible oils. In the last four decades, much progress has been made in the chemistry of volatile products of lipid oxidation, mainly as a result of advances in separation techniques and analytical methodology, particularly gas chromatography-mass spectrometry. [Pg.428]

Lipids tend to survive better than other organic compounds in archaeological contexts and are amenable to sensitive methods of analysis such as gas chromatography/mass spectrometry (GC/MS). Their insolubility in water increases then-chances for survival. Lipids have been recovered from sediments that are millions of years old and have been identified in materials where no cellular structure remains. Lipids are also important because of their specificity. Certain kinds of lipids differ greatly not only between plants and animals, but among the various families and genera of plants and animals. [Pg.104]

Using HPLC and gas chromatography-mass spectrometry (GC-MS), Mabuchi and Nakahashi (M6) and Takeda et al. (T2) have identified the compound as 3-carboxy-4-methyl-5-propyl-2-furanpropanoic acid (CMPF) (Fig. 5). This substance, first detected in normal urine (S31) and later in uremic sera (L9, M3), belongs to a new class of endogenous metabolites called urofuranic acids (Fig. 6). Although fiiranoid fatty acids with similar chemical structures have been found in lipids in the liver and testes of several fish species, the source and metabolism of... [Pg.74]
