Download or read book Mass Spectra and GC Data of Steroids written by Hugh L. J. Makin and published by Wiley-VCH. This book was released on 1998 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the most comprehensive collection of mass spectral data for steroids available today. It contains some 2,500 newly measured EI(+) mass spectra of androgens and estrogens and their derivatives (trimethylsilyl ethers, O-methyloximes and acetates). Each spectrum is accompanied by the structure, systematic and trivial names, retention index, molecular formula, molar mass, CAS number and sample source of the steroid, with all data obtained using the same mass spectrometer under identical chromatographic and mass spectrometric conditions. Steroids are of considerable therapeutic importance, and the collection will thus be of particular interest to the pharmaceutical industry, as well as an invaluable data source for chemists and biochemists involved in drug development, drug screening and clinical toxicology, endocrinologists, natural products chemists and mass spectroscopists

Download or read book Modern Methods of Steroid Analysis written by Erich Heftmann and published by Elsevier. This book was released on 2012-12-02 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern Methods of Steroid Analysis reviews modern methods of steroid analysis such as liquid column chromatography, mass spectrometry, and gas chromatography. Topics covered include qualitative and quantitative analysis of plant sterols by gas-liquid chromatography; Raman spectroscopy of steroids; nuclear magnetic resonance; and applications of lanthanide shift reagents. A computerized method for rapid comparison and retrieval of infrared spectral data is also described. This volume is comprised of 22 chapters and begins with an analysis of hormonal steroids using liquid column chromatography, followed by a discussion on the separation of insect molting hormones using high-pressure liquid chromatography. The reader is methodically introduced to the application of gradient elution and thin-layer chromatography to the analysis of corticosteroids and 17-ketosteroids, as well as some aspects of mass spectrometry in steroid analysis. Subsequent chapters explore other methods such as optical rotatory dispersion and circular dichroism, along with radioisotope techniques. In particular, the radioimmunoassay of plasma steroid hormones and plasma aldosterone is considered. This book should be of interest to biochemists.

Download or read book Steroids and their Medicinal Potential written by Abid Hussain Banday and published by Bentham Science Publishers. This book was released on 2023-07-18 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Steroids are an important class of biomolecules with diverse roles and functions. Besides being important as structural and signaling molecules, these molecules hold promise against numerous disorders, including cardiovascular conditions, cancer, inflammation, and autoimmune disorders. Many investigations have demonstrated that steroidal frameworks may provide lipid solubility, receptor selectivity, or membrane binding properties to non-steroidal pharmacophores. However, the therapeutic use of steroids can be dangerous when they're used incorrectly. Additionally, misconceptions about steroids among athletes or recreational users can lead to steroid abuse and poor health outcomes. Steroids and their MedicinalPotential discusses the classification, distribution, biosynthesis, chemical synthesis, and semi-synthesis of different steroids. The medicinal potential of each class is exhaustively discussed in different chapters. The latest advances and developments in steroid-based drug discovery are also discussed thoroughly. The book aims to address general questions and concerns about steroids, providing readers with a useful resource on the subject. Key Features -Provides comprehensive coverage on all aspects of steroids including steroid chemistry, biochemistry, medicinal potential, drug discovery, and advances in target-binding interactions of steroid-based drugs -Includes chapters dedicated to anabolic steroids and their abuse -Designed as an accessible source of information for understanding steroidal drugs with structured chapters-Includes references for advanced readers.

Download or read book Gas Chromatography and Mass Spectrometry A Practical Guide written by O. David Sparkman and published by Academic Press. This book was released on 2011-05-17 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of Gas Chromatography and Mass Spectrometry: A Practical Guide follows the highly successful first edition by F.G. Kitson, B.S. Larsen, and C.N. McEwen (1996), which was designed as an indispensible resource for GC/MS practitioners regardless of whether they are a novice or well experienced. The Fundamentals section has been extensively reworked from the original edition to give more depth of an understanding of the techniques and science involved with GC/MS. Even with this expansion, the original brevity and simple didactic style has been retained. Information on chromatographic peak deconvolution has been added along with a more in-depth understanding of the use of mass spectral databases in the identification of unknowns. Since the last edition, a number of advances in GC inlet systems and sample introduction techniques have occurred, and they are included in the new edition. Other updates include a discussion on fast GC and options for combining GC detectors with mass spectrometry. The section regarding GC Conditions, Derivatization, and Mass Spectral Interpretation of Specific Compound Types has the same number of compound types as the original edition, but the information in each section has been expanded to not only explain some of the spectra but to also explain why certain fragmentations take place. The number of Appendices has been increased from 12 to 17. The Appendix on Atomic Masses and Isotope Abundances has been expanded to provide tools to aid in determination of elemental composition from isotope peak intensity ratios. An appendix with examples on "Steps to follow in the determination of elemental compositions based on isotope peak intensities" has been added. Appendices on whether to use GC/MS or LC/MS, third-party software for use in data analysis, list of information required in reporting GC/MS data, X+1 and X+2 peak relative intensities based on the number of atoms of carbon in an ion, and list of available EI mass spectral databases have been added. Others such as the ones on derivatization, isotope peak patterns for ions with Cl and/or Br, terms used in GC and in mass spectrometry, and tips on setting up, maintaining and troubleshooting a GC/MS system have all been expanded and updated. - Covers the practical instruction necessary for successful operation of GC/MS equipment - Reviews the latest advances in instrumentation, ionization methods, and quantitation - Includes troubleshooting techniques and a variety of additional information useful for the GC/MS practitioner - A true benchtop reference - A guide to a basic understanding of the components of a Gas Chromatograph-Mass Spectrometer (GC-MS) - Quick References to data interpretation - Ready source for information on new analyses

Available in PDF, EPUB and Kindle. Book excerpt: The volumes of this classic series, now referred to simply as "Zechmeister" after its founder, L. Zechmeister, have appeared under the Springer Imprint ever since the series' inauguration in 1938. It is therefore not really surprising to find out that the list of contributing authors, who were awarded a Nobel Prize, is quite long: Kurt Alder, Derek H.R. Barton, George Wells Beadle, Dorothy Crowfoot-Hodgkin, Otto Diels, Hans von Euler-Chelpin, Paul Karrer, Luis Federico Leloir, Linus Pauling, Vladimir Prelog, with Walter Norman Haworth and Adolf F.J. Butenandt serving as members of the editorial board. The volumes contain contributions on various topics related to the origin, distribution, chemistry, synthesis, biochemistry, function or use of various classes of naturally occurring substances ranging from small molecules to biopolymers. Each contribution is written by a recognized authority in his field and provides a comprehensive and up-to-date review of the topic in question. Addressed to biologists, technologists and chemists alike, the series can be used by the expert as a source of information and literature citations and by the non-expert as a means of orientation in a rapidly developing discipline.
