Description 6 TWENTY-SECOND ANNUAL REYNOLDS LECTURE coveries of X-rays and radioactivity. Exciting developments in our understanding of the substances which promote chemical reactions in cells and of the mode of operation of genetic factors have occurred recently. We have obtained some glimpses into the nature of these processes and because the tools are becoming available to attack these problems, progress will come at an accelerating rate. I have said that these problems are exciting; nothing is of greater interest to living beings than the nature of life. In recent years, we have come to appreciate more and more the unity of life, for the underlying structural basis and the chemical mechanisms present in all organisms existing at present appear to be much the same. This evening only a few recent developments can be mentioned and, with the kind indulgence of my scientific colleagues, they will be discussed with as little technical jargon as possible. Before proceeding to more complex matters, we might first review very briefly some fundamental aspects of Biochemistry and thus put in perspective the developments which concern our understanding of the machinery of the living cell and of the inherited factors which serve to guide the formation of this machinery. In the simplest sense, there are two major aspects of the study of the chemistry of living cells. One is the behavior of the molecules which are derived from the diet. These are transformed to substances which can serve as sources of energy which cells need to perform work, or they can be utilized for the synthesis of the structural components of cells. The other type of fundamental study concerns the structure and behavior of the large molecules, which constitute the machinery of the cell itself. These problems, which are similar for all living cells, are the ones with which we shall be concerned more immediately. We shall leave for others to discuss the integrative aspects which exist in higher organisms where cells are differentiated, both structurally and functionally. Ill There are three main types of large molecules in living cells. These are the carbohydrates, consisting of simple and complex sugars, the lipids, including the ordinary fats, and the proteins. Lipids and carbohydrates serve mainly as energy stores or as inert supporting structures of cells. Some proteins also serve as insulators or skeletal supports but their principal importance resides in the
