Lipid characterized

The results for bacterial whole-cell analysis described here establish the utility of MALDI-FTMS for mass spectral analysis of whole-cell bacteria and (potentially) more complex single-celled organisms. The use of MALDI-measured accurate mass values combined with mass defect plots is rapid, accurate, and simpler in sample preparation then conventional liquid chromatographic methods for bacterial lipid analysis. Intact cell MALDI-FTMS bacterial lipid characterization complements the use of proteomics profiling by mass spectrometry because it relies on accurate mass measurements of chemical species that are not subject to posttranslational modification or proteolytic degradation. 

There are a huge number of applications of GC/MS to lipid analysis in cultural heritage reported in the literature. Lipid characterization, together with the study of lipid degradation processes, is an important research area in conservation science [1 31].

General. Chloroform, methanol, ether, and acetone were obtained from Burdick and Jackson. All other chemicals and solvents were purchased from Aldrich Chemical Company. Triple distilled water was used in the lipid characterization studies. Polymerizable diacetylenic lipid 1,2 bis (tricosa-10,12-diynoyl)-sn-glycero-3-phosphocholine was synthesized following the procedure developed in our lab (24). Synthetic intermediates and lipids were characterized by IR (Perkin-Elmer 1800 FT-IR), and NMR (Brucker MSL-360 300 MHz) Spectrometer. Purity of all the compounds was monitored by thin layer chromatography on silica gel. M. Merck) using chloroformimethanol water (65 25 4, Solvent A) for lipid 1 and... 

Steroids are a class of lipids characterized by a sterane core and additional functional groups. Hundreds of distinct steroids are found in plants, animals, and fungi. It is possible to classify steroids based on their chemical composition into cholestanes (e.g., cholesterol), cholanes (e.g., cholic acid), pregnanes (e.g., progesterone), and androstanes (e.g., testosterone and androgen). Steroids play many important biological roles, often as hormones interacting with specific receptors. The hydrophobic...
