Book reviews RODD'S CHEMISTRY OF CARBON COMPOUNDS. 2nd edn. Editor: S. Coffey. Vol. 1. Part F: Carbohydrate Chemistry. Pp. xvi + 780 (1967). Elsevier, Amsterdam, London, New York. oe14.75. Not only is this volume a welcome addition to the second edition of Rodd's Chemistry of Carbon Compounds but it is a useful acquisi- tion to present-day literature of organic chemistry. In the period since the publication of the first edition there have been major advances in organic chemistry. The present volume significantly differs from its predecessor in its use of modern physico-chemical techniques and there are sections dealing with the pro- perties of the monosaccharides in terms of crystal structure, infra-red and nuclear magnetic resonance spectroscopy, mass spec- trometry, optical rotatory dispersion and molecular disymmetry. The various chromato- graphic techniques---column, paper, thin- layer, gas-liquid and paper electrophoresis-- for the separation, identification and estima- tion of monosaccharides are finding wide- spread application in qualitative and quan- titative work and these are dealt with most efficiently. The use of radio-active isotopes is not forgotten either. Whilst most work in this field has concerned use of •4C, the authors correctly refer to the value of deuterium and tritium in the investigation of biochemical processes and in the study of reaction mech- anisms of carbohydrates. Almost all the volume under review is concerned with saccharide chemistry but the short opening chapter describes the penta-, hexa-, and higher polyhydric alcohols. All in all, this work is to be recommended. It is a well printed and well set-out book in which the structural formulae, usually a difficult problem with carbohydrates, are very clearly drawn. C.B. 73 STRUCTURE AND BONDING. Vol. 7. Editors: P. Hemmerich, C. K. Jorgensen, J. B. Neilands, Sir Ronald S. Nyholm, D. Reinen and R. J.P. Williams. Pp. 154+Ill. (1970). DM. 38.00 $10.50. Vol. 8. Pp. 196 -• Ill. (1970) DM. 42. Springer-Verlag, Berlin, Heidelberg, New York. The Editors see this series as providing a discussion of structure and bonding in com- plexes, covering both chemical physics and biological chemistry. It is not restricted to organic chemistry and is an excellent medium for what is necessarily a multi-disciplinary field. There is little of direct practical concern to the cosmetic chemist in the present two volumes, but they will be invaluable to the research worker studying the particular subjects under review. Volume 7 includes work on the spectra of ferric haems and haemoproteins, the absolute configuration of transition metal complexes, the application of nuclear quadrupole resonance spectroscopy to the study of transition metal compounds and a paper in German-- Kationenverteilung zweiswetiger 3d-nIonen in oxidischen Spinell-, Granat- und anderen Strukturen. Volume 8 studies iron electronic configura- tions in proteins (studies by Mossbauer spectroscopy), structural studies of haemes and haemoproteins by nuclear magnetic resonance spectroscopy, the clinical nature and reactivity of cytochrome P-450 and cobalt (II) in metalloenzymes. It is thought that a list of the subject matter in these books will be of value since the papers are so specialized. M.A. COOKE
