"Biochemistry of Catalysts" is intended for those who wish to understand living organisms, especially man. Biochemistry is Essential for this purpose, but it would be almost impossible for a Student to survey on his own the massive body of existing knowledge, constantly augmented by a remarkable torrent of brilliant discoveries. The Purpose of the book, then is to organize our Knowledge into something that can be comprehended in a relatively short time and still convey a reasonable complete Picture of the chemical structure and function of man. Readability without sacrifice of coverage has been a prime goal. An important device in gaining that goal is to keep attention constantly focused on function, with repeated use of rationalization to show that the chemical facts are not isolated, but part of a whole. Biochemistry has two major goals as a fundamental science, it treats the vital functions from the standpoint of Physical chemistry, and as an applied discipline, it points out practical applications for the Wealth of Scientific knowledge it has acquired.
