Thus, as beer volatile components represent the major contributors for beer overall and peculiar aroma properties, this work intends to perform an in-depth profiling of lager beer volatile metabolites and to generate new data that may contribute for molecules’ identification, by using multidimensional gas chromatography. A set of lager beers were used as case-study, and 329 volatile metabolites were determined, distributed over 8 chemical families: acids, alcohols, esters, monoterpenic compounds, norisoprenoids, sesquiterpenic compounds, sulfur compounds, and volatile phenols. From these, 96 compounds are reported for the first time in the lager beer volatile composition. Around half of them were common to all beers under study. Clustering analysis allowed a beer typing according to production system: macro- and microbrewer beers. Monoterpenic and sesquiterpenic compounds were the chemical families that showed wide range of chemical structures, which may contribute for the samples’ peculiar aroma characteristics.

    Journal of Physiology (1991), 437, pp. 431-448 431 With 11 figures Printed in Great Britain ACTIONS OF n-ALCOHOLS ON NICOTINIC ACETYLCHOLINE RECEPTOR CHANNELS IN CULTURED RAT MYOTUBES BY R. D. MURRELL*, M. S. BRAUNt AND THE LATE D. A. HAYDON From the Physiological Laboratory, University of Cambridge, Downing Street, Cambridge CB2 3EG (Received 14 June 1990) SUMMARY 1. The actions of the n-alcohols from pentanol to dodecanol on nicotinic acetylcholine receptor (nAChR) channels were investigated by recording single ACh- activated channel activity from inside-out membrane patches isolated from cultured rat myotubes. Alcohols were applied to the cytoplasmic side of the membrane; aqueous concentrations ranged from 11 7 mM-pentanol to 0-02 mm-dodecanol. 2. The intermediate-chain alcohols (pentanol to octanol) caused channel currents to fluctuate between the fully open and closed state level so that openings occurred in bursts interrupted by brief gaps. Closed time distributions were fitted well with two exponential components, the fast component representing the closures within a burst. The number of gaps within a burst was dependent on alcohol concentration whereas gap duration was independent of concentration but increased with increasing chain length of the alcohol up to octanol. 3. Nonanol and decanol reduced the mean duration of bursts of openings but did not cause an increase in the number of short closed intervals within a burst. Beyond decanol there was a decline in the ability of the n-alcohols to affect channel function. A saturated solution of undecanol (0-07 mM) reduced the mean open time by 33+17 %, whereas a saturated solution of dodecanol had no significant effect.

    Acknowledgement I would like to thank my advisor Prof. Zachary T. Ball for teaching me everything I know in synthetic skills during my first year and guiding me through the rest of my time here at Rice. He has helped me better myself through constant constructive criticism, both in research and writing. I would also like to thank past and present Ball group members, Dr. Brian Popp, Dr. Alex Zaykov, Dr. Jessica Herron, Vincenzo Russo, Ramya Sambasivan, Cara Bovet, Zhen Chen, Dr. Jane Coughlin, Farrukh Vohidov, Matt Minus, Rob Ferguson, Julian Cooper. They have been a very good support in discussing research, exchanging ideas, and have become great pals in the last few years. Especially, Brian and Ramya’s encouragement in tough times is really valued. I thank my friends Rajkishore Barik and Meenu Adhikari for making Houston a second home. Again, Ramya Sambasivan for being a very good friend and always a willing ear to vent out frustrations associated with the graduate life and Avani Verma for bringing all kinds of fun in life and being so encouraging during my panic moments in thesis writing process. I would like to take this opportunity to express my gratitude and respect for my father Kuru Ram, and mother Amita Kundu, for the confidence and faith they always had in me, my sister Aruna Hajra who always supported me in my endeavors. I would like to thank my fiancée Soumya Sarkar, for his never wavering trust, love and support throughout my Ph.D in our 6 yr long, long- distance relation. Last but not least thanks to everyone who cared! -Rituparna Kundu Abstract Developing Dirhodium-Complexes for Protein Inhibition and Modification & Copper-Catalyzed Remote Chlorination of Alkyl-Hydroperoxides by Rituparna Kundu The work describes the development of a new class of protein-inhibitors for protein-protein interactions, based on metallopeptides comprised of a dirhodium metal center.
