Book Description
The properties of proteins are determined not only by the sequence of amino-acid residues in the polypeptide chains, but also by the con figuration of the chains-the way in which the chains are coiled or folded. It is probable that denaturation, the loss of some of the specific properties of a native protein, may in many cases be the result simply of a change in configuration of the polypeptide chains, without any change whatever in the sequence of amino-acid residues. During the past few years great progress has been made in the attack on the determination of the sequence of amino-acid residues in the poly peptide chains of proteins, through the work of SANGER and his collabora tors (Io9, IIO) and of other investigators. There has also been significant progress in the attack on the problem of the configuration of polypeptide chains, largely through the application of the X-ray diffraction technique.

Book Description
The volumes of this classic series, now referred to simply as "Zechmeister” after its founder, L. Zechmeister, have appeared under the Springer Imprint ever since the series’ inauguration in 1938. The volumes contain contributions on various topics related to the origin, distribution, chemistry, synthesis, biochemistry, function or use of various classes of naturally occurring substances ranging from small molecules to biopolymers. Each contribution is written by a recognized authority in his field and provides a comprehensive and up-to-date review of the topic in question. Addressed to biologists, technologists, and chemists alike, the series can be used by the expert as a source of information and literature citations and by the non-expert as a means of orientation in a rapidly developing discipline.

Book Description
Since the late 1950's when proton n. m. r. spectroscopy was first used in organic natural products studies the technique has increasingly con of this important area of chemistry. tributed to the rapid advancement Although the potential utility of 13C n. m. r. was recognized very early, essentially no application of 13C n. m. r. appeared in the literature prior to 1966 and 95% of the existing data are less than five years old. The initially slow growth had its cause in inadequate instrumentation, insufficient sensitivity being the main obstacle. This situation drastically changed with the advent and commercial availability of broadband ex citation and Fourier transform methods, giving natural-abundance 13C n. m. r. and its numerous chemical applications a tremendous impetus. Today BC spectra can be recorded on sample quantities down to the submilligram level, which until recently even withstood proton n. m. r. Paralleling the development of experimental techniques considerable progress has also been made on an understanding of spectral parameters, in particular their stereochemical implications on natural products. Although the large majority of data present up to now deals with known structures, an adequate basis now exists which allows the chemist to use the technique for tackling real problems on unknown molecules.
