The text under review is designed for use in an introductory-level course in bioinorganic chemistry, a field that has only recently come of age. Most institutions do not yet offer a separate undergraduate course in this area, but rather include selected topics in a regular inorganic chemistry course. However, anyone teaching such a course would find this text worthy of consideration. Since not many introductory-level texts are available, this is a welcome addition to the relatively short list.
The authors mention that this book is a result of a
two-semester course taught at two German universities.
Basic knowledge of chemistry and biochemistry acquired in
the first year at university level is considered sufficient
background for this course sequence. This would not be the
case at most U.S. institutions. Owing to the highly
interdisciplinary nature of the area, at least a semester each of
inorganic chemistry and biochemistry beyond the usual the
organic and physical chemistry would be recommended.
Thus, this text would be more suitable for a course at the
senior, possibly junior, level.
The authors aspire to comprehensive coverage of
their subject. The 19 chapters cover a wide range of topics,
which are treated in sufficient depth. Literature references up
to 1993 are cited at the end of each chapter. The first
chapter provides a brief historical background of the subject,
and the second provides the basis for examining living
systems and their processes from an inorganic perspective. The
function of inorganic elements required by these systems,
biomolecules that are potential ligands, and metals in
various roles are examples of some topics surveyed in this
chapter. It concludes with a discussion of the approach used by
inorganic chemists to study biological systems, namely,
utilizing model compounds.
Of the remaining chapters, 12 are devoted to the
occurrence and participation of particular elements in
various processes. For example, one chapter is devoted to
nickel-containing enzymes and another to copper-containing
proteins; yet another looks at the biological functions of
molybdenum, tungsten, vanadium, and chromium. Biomineralization, functions of nonmetallic elements,
and bioinorganic chemistry of toxic metals are each treated in
a separate chapter. The final two chapters deal with
medical applications of radionuclides and chemotherapeutic
compounds.
In the individual chapters, before the
bioinorganic chemistry of an element(s) is discussed, the relevant
basic chemistry is reviewed first when appropriate. For
instance, in Chapter 5 on dioxygen, the properties of this
molecule and its behavior as an oxidant are first examined, as
are its various modes of coordination to metals. In other
cases, the overview of the chapter provides background
information of a biochemical nature, such as in the chapter on
ironsulfur proteins, which first reviews their occurrence
and function in a variety of situations. Also given
throughout the text are "boxed sections", which are used to review
or introduce specific ideas pertinent to the discussion at
hand. In Chapter 2, for example, hardsoft interactions and
the basics of ligand field theory are reviewed in this way.
Theoretical background on physical methods used to obtain
important evidence is also provided briefly in boxed
sections. In the case of alkylcobalamins, for example, EPR is used
to determine which of the three possible pathways for
CoC bond cleavage, each resulting in a different intermediate,
is likely under physiological conditions. A short discussion
of this technique is thus included. In a later chapter, more
on EPR is given in another boxed section, but this further
development is necessary to the topic of discussion in
that chapter. These brief interludes are quite effective in
that they do not unduly distract the reader from the main
discussion.
While there is naturally a certain amount of
referring to earlier sections, the chapters are sufficiently
free-standing to permit a course to utilize a selection of chapters,
even in a sequence different from that in the text. I have
offered a one- or two-credit course called "Special Topics in
Inorganic Chemistry", in which topics from bioinorganic
chemistry can be covered in some depth. I would consider
adopting this text the next time the course is offered and using
a few selected chapters.
The fact that the book is a product of courses
already taught is an advantage. The organization and the way
the material is treated is student-tested. In conclusion,
this would make a very good primary text for a course
in bioinorganic chemistry for students with the
necessary background. It would not be easy to cover the entire text
in a single semester, but a good selection of chapters
resulting in a coherent course may be put together without much
difficulty.
