Book Reviews COMPREHENSIVE BIOCHEMISTRY• VOL. 17: CARBOHYDRATE METABOLISM, Edi,ted by Marcel Florkin and Elmer H. Stotz. American Elsevier Pub- lishing Co., Inc. New York, N.Y. 1969. $08 pages, indexed. Price $17.00. Vol. 17 of this series, "Carbohy- drate Metabolism," is divided into seven chapters. The first four of these concern themselves with review- ing the major aspects of carbohydrate metabolism commencing with a brief discussion of the mechanisms of in- testinal transport of simple sugars. The second chapter on glycogen, starch, and cellulose synthesis and breakdown is an extensive and well- referenced ($51) discussion of the individual enzymes concerned with particular emphasis being placed on phosphorylase and glycogen synthe- tase. Chapters III and IV deal with Glycolysis and Hexose-Monophos- phate Oxidation, respectively, with primary emphasis again being placed on the regulation and mechanism of the enzymes involved in each bio- chemical process. The remaining chapters deal with more specialized areas of carbohy- drate metabolism which are more 199 often found as the subjects of sep- arate reviews or monographs. The first of these deals with the metabo- lism of carbohydrate in brain tissue, followed by an interesting review of aldonic and uronic acids. The last chapter, "The Metabolism of Gly- cosaminoglygans," concerns itself with amino sugars and mucopolysac- charides. In general, the material in this vol- ume is largely restricted to mam- malian metabolism of carbohydrate with only limited excursions into bacterial, yeast, or higher plant bio- chemistry. As such, the first [our chapters provide interesting reading into the fa.te of carbohydrates from salivary ovamylase to the generation of high-energy phosphate com- pounds. Each author tends to pre- sent his material in a well-organized concise manner, touching on the highlights of each topic without ex- hausting detail. However, the chap- ters are well-referenced and provide ample opportunity [or the reader to obtain considerable supplemental reading material should he so desire. In general, all of the contributors to this volume bring together valu- able information in specialized areas
