Biochemistry is a fundamental subject in medicine, founded on general chemistry, physics and biology. This book assumes that the student has training in these subjects. While it is intended to be a practical companion to the general subject of biochemistry, considerable explanatory matter is added to help correlate the subject and to save time for the student. It aims to combine the quantitative methods of the chemist with the comparative ones of the biologist. Throughout, one encounters valuable suggestions that only experience can give. For example, in the determination of urea by the Folin-Wu method, "Never add paraffin oil or caprylic alcohol or other alcohols to prevent foaming. They interfere with nesslerization later." The book is divided into three parts, which are subdivided into thirteen chapters, as follows: 1. Cell constituents—carbohydrates, lipins, proteins, nucleoproteins and nucleic acids, hydrogen ion concentration. 2. The chemistry of the digestive tract—salivary digestion, gastric digestion,
