Full Description
Thoroughly updated edition of the leading textbook on carbohydrate chemistry
From synthesis to biological function, Essentials of Carbohydrate Chemistry and Biochemistry introduces the entire range of modern carbohydrate chemistry and chemical biology. In this new edition, the increasing recognition of the role of carbohydrates in biology, pharmacology, and medicine is reflected in greatly expanded sections on glycobiology and glycomimetics. The new edition also features a new set of illustrations, many of which are now in color, as well as intriguing practical examples and story-telling text boxes providing context for the relevance of carbohydrates in science and society.
Didactically written by an experienced lecturer and graduate student advisor, Essentials of Carbohydrate Chemistry and Biochemistry includes information on:
Protecting groups for carbohydrates, including protection of the anomeric center, acyl, ether, and acetal protecting groups
Methods for the analysis of carbohydrates, covering polarimetry, NMR spectroscopy, and mass spectrometry
Important modifications and functionalizations of the sugar ring, such as deoxy derivatives, anhydro sugars, and epimerizations
Principal approaches to the chemical and enzymatic synthesis of glycosides and glycopeptides, and modern examples of advancing the art of glycoside synthesis employing solution as well as solid phase methods
Structural diversity and biosynthesis of oligosaccharides and glycoconjugates
A greatly expanded section on glycobiology that focuses on the role of carbohydrates in membrane architecture, cell-cell-recognition. cell adhesion, and their biomedical applications
Updated and thoroughly modernized for more efficient classroom teaching and self-learning, the Fourth Edition of Essentials of Carbohydrate Chemistry and Biochemistry is essential reading for students in chemistry, biochemistry, biotechnology, and pharmacy with an interest in glycochemistry and glycobiology.
