In the few years since the first edition of this book made its appearance, under takings in the area of protein sequence determination have increased at an almost logarithmic pace.

Enzyme kinetics has undergone very rapid growth and development during the past fifteen years and has been well received by the biochemical community.

These reac tions, in accord with CZAPEK (1921) and PAECH (1950), are summed up under the term "secondary metabolism", and their products are called "secondary metabolites.

A systematic study traced the cause of this absorption, showing that the covered frequency range and the intensity of the absorption were related in a predictable manner to the rate at which ions can interact and form structures differing in volume from the non interacting species.

The principles described in the latter discus sions are broadly applicable, for example to the promising tech niques of X-ray spectroscopy (utilizing synchrotron radiation) and lanthanide-perturbed, very high-resolution nuclear magnetic resonance spectroscopy.
