Rapid progress in the field of sialic acids has made it desirable to
collect the new data about these unique sugars and to continue the
series of books on this topic. In 1960, A. GOTTSCHALK wrote "The
Chemistry and Biology of Sialic Acids and Related Substances" (Cambridge
University Press) and in 1976, A. ROSENBERG and C. -L. SCHENGRUND
published "Biological Roles of Sialic Acids" (Plenum Press). In this
book emphasis is given to various modern methods used in the isolation
and analysis of sialic acids. New approaches to the synthesis of free
and bound sialic acids are described and the vast field of occurrence
and metabolism of these substances is reviewed. Sialidoses are dealt
with in one of the chapters, because sialidases have been recognized as
factors of pathophysiological im- portance. As knowledge is increasing
about the involvement of sialic acids in many aspects of cell biology,
another chapter is devoted to these phenomena. With this book I intend
to demonstrate modern trends in sialic acid chemistry and biochemistry,
and I hope that it will be of practical use and find its place in
laboratories rather than in libraries. This publication offers an
opportunity to thank all colleagues in many countries, including my
coworkers at the universities of Bochum and Kiel, for their cooperation,
stimulating discussions and, very important, useful criticism. The
continuous cooperation with J. F. G. VLIEGENTHART and his coworkers,
Utrecht, has been rewarding in many respects.
