E-Book Overview
Bound carbohydrates are an important and fascinating topic in biochemical and cancer research. Based on a series of invited lectures, this book focuses on the special role that bound carbohydrates play in nature and reflect the author's distinguished career in biochemical research. Some other topics covered are the properties of membrane glycoproteins, involved in the resistance of cells to drugs, and the metabolism of sugars and sialic acids, both of which form a pivotal role in the author's studies. The book chronicles just some of the huge advances that have been made in biochemistry over the past few decades.
E-Book Content
This book is based on a series of lectures delivered under the auspices of the University of Siena. The contents reflect and delineate the author's biochemical research. In particular, the book focuses on the special role played by bound carbohydrates in nature. The complexity of these enigmatic compounds is examined through special case studies including glycoproteins and the metabolism of sialic acids. This book will be of interest, not only to those working in biochemistry and molecular biology, but also to those in the pharmaceutical industry. It provides an entertaining and first hand account for researchers and graduate students. Bound carbohydrates in nature Lezioni Lincee Sponsored by Foundazione IBM Italia Editor: Luigi A. Radicati di Brozolo, Scuola Normale Superiore, Pisa This series of books arises from lectures given under the auspices of the Accademia Nazionale dei Lincei and is sponsored by Foundazione IBM Italia. The lectures, given by international authorities, will range on scientific topics from mathematics and physics through to biology and economics. The books are intended for a broad audience of graduate students and faculty members, and are meant to provide a 'mise au point' for the subject they deal with. The symbol of the Accademia, the Lynx, is noted for its sharp sightedness; the volumes in the series will be penetrating studies of scientific topics of contemporary interest.
