After an introduction into the main importance of chromium (bio)chemistry, and more specifically the oxo-chromium(V)-sugar complexes, a general overview is given of the current state-of-the-art EPR techniques. The next step reviews which types of EPR spectroscopy are currently applied to oxo-Cr(V) complexes, and what information about these systems can be gained from such experiments. The advantages and pitfalls of the different approaches are discussed, and it is shown that the potential of high-field and pulsed EPR techniques is as yet still largely unexploited in the field of oxo-Cr(V) complexes. Subsequently, the discussion focuses on the analysis of oxo-Cr(V) complexes of different types of sugars and the implications of the results in terms of understanding chromium (bio)chemistry.","PeriodicalId":7215,"journal":{"name":"Advances in carbohydrate chemistry and biochemistry","volume":"66 ","pages":"69-120"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/B978-0-12-385518-3.00002-X","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30289074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article details the synthesis, conformational analysis, and protein-binding properties of septanose carbohydrates. A distinction is drawn between septanoses that are substituted in the 6-position of the ring and those that are not. When a C-6 substituent is absent, the structure is essentially that of an aldohexose in its septanose, rather than furanose or pyranose, ring form; they may play as-of-yet unexplored roles in glycobiology. Septanoses having a hydroxymethyl group at C-6, on the other hand, are ring-expanded analogues of pyranoses. Syntheses have moved beyond the preparation of seven-membered ring monosaccharides to the development of septanosyl donors. These donors have been used in the synthesis of novel di- and trisaccharides that contain septanoses as well as a variety of glycoconjugates. Low-energy conformations adopted by septanoses have been organized based on ring substitution and stereochemistry. Instances where septanoses have been demonstrated to bind to natural proteins are presented and analyzed. The major conclusion drawn in the chapter is that advances in the synthesis of septanose carbohydrates now enable a detailed investigation of their activity in a number of biological contexts.","PeriodicalId":7215,"journal":{"name":"Advances in carbohydrate chemistry and biochemistry","volume":"66 ","pages":"121-86"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/B978-0-12-385518-3.00003-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30289075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lists of graduate students, post-doctoral fellows, and sabbatical visitors are provided for this period. Following a generous endowment by Dr. Herchel Smith, Professor Hall built a new Department of Medicinal Chemistry at Cambridge University, UK, and greatly expanded his researches into the technology and applications of magnetic resonance imaging (MRI) and zero quantum NMR. MRI technology was applied both to medical problems such as the characterization of cartilage degeneration in knee joints, the measurement of ventricular function, lipid localization in animal models of atherosclerosis, paramagnetic metal complexes of polysaccharides as contrast agents, and studies of many other anatomical features, but also to several aspects of materials analysis, including food analyses, process control, and the elucidation of such physical phenomena as the flow of liquids through porous media, defects in concrete, and the visualization of fungal damage to wood. Professor Hall's many publications, patents, lectures, and honors and awards are described, and also his successful effort to keep the Asilomar facility in Pacific Grove, California as the alternating venue for the annual Experimental NMR Conference. Two memorial services for Professor Hall are remembered.","PeriodicalId":7215,"journal":{"name":"Advances in carbohydrate chemistry and biochemistry","volume":"65 ","pages":"10-43"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/B978-0-12-385520-6.00002-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30010325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
