Taschenbuch. Condition: Neu. Druck auf Anfrage Neuware - Printed after ordering - The present volume is the first of two planned to provide state-of-the-art expert reviews of central topics in modern natural products chemistry and secondary metabolism. Many scientists not directly involved in these areas still view the field of natural products as focused primarily on the isolation,structure elucidation, and cataloging of new compounds (i. e. 'grind and find'),or on their chemical synthesis. However,two revolutions in experimental techniques since the early 1950's have completely transformed the understanding of chemical and biological relationships between highly diverse natural products. The first was the use isotopes to label precursors and follow the fate of key atoms during biochemical transformations to a final product. Advances in methodology that began in the mid-1970's,especially using NMR to detect stable isotopes,dramatically expanded the level of mechanistic detail available to study in vivo conversions of secondary metabolites. The second revolution started in the late 1980's as researchers developed methods to identify,purify and genetically manipulate individual enzymes - sponsible for the intricate steps leading to complex natural products. This has expanded the field from building an encyclopaedia of natural materials to being able to initiate control of biochemical pathways to secondary metabolites. Recent advances suggest it may soon be possible to rationally manipulate biochemical pathways in vivo to rapidly produce almost any target molecule,including n- natural variants,in substantial quantity.…

The Poet's Corner is illustrated with a frontispiece and twenty-four further plates; The Leaves of Southwell contains a frontispiece and thirty-two plates; The Bayeux Tapestry contains a frontispiece, eight colour plates, and over eighty further monochrome illustrations; English Book Illustration contains a frontispiece, followed by eight colour and eight monochrome plates; A Selection of Engravings features illustrated endpapers and thirty uninterrupted illustrations to the rear; British Military Uniforms contains twenty-four colour plates; Woodcuts of Albrecht Durer features 111 illustrations; Ballooning contains thirty-two plates in both colour and monochrome; both copies of Edward Gordon Craig contain a frontispiece and forty additional plates in colour and black and white; Greek Terracottas contains fifty-four plates; A Book of Scripts contains sixty-four plates; and Monumental Brasses contains thirty-two colour plates. All remaining works are illustrated with sixteen plates, a number of which are in colour. Further in-text examples can also be found throughout the collection. Collated, complete. All works are bound in the publisher's original pictorial paper-backed boards. Greek Terracottas, A Book of Scripts, Medieval Carvings and Monumental Brasses are each accompanied by the original dust wrapper, Greek Terracottas being clipped and all remaining examples being unclipped. Flowers of Marsh and Stream contains the discreet stationer's bookplate of W. L. Cameron to the front paste down. British Military Uniforms is signed by the previous owner to the front paste down.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is concerned with discovering the chemical pathways of biosynthesis. The four chapters cover the use of isotopes in biosynthetic research and the biosynthesis of enzyme cofactors and vitamin B12 and of reduced polyketides such as erythromycin. The topics covered demonstrated the revolution that has occurred in biosynthetic studies withthe advent of gene cloning and overexpression. The knowledge of biosynthetic pathways at the genetic and enzymic levels which is becoming available opens up possibilities of designing inhibitors of particular steps as new antibiotics or manipulating the genes so that new natural products are produced. However the book also shows that the more classical approach to biosynthetic studies must go hand in hand with these new techniques. 204 pp. Englisch.…
