Description CHEMICAL KEYS TO AN UNDERSTANDING OF LIFE PROCESSES 21 In this egg were all the potentialities for the development of a human being, complete as to organs and tissues such as heart, lungs, liver, sex organs and a brain. Just imagine not only the complexity but the beauty of this integrated development in terms of chemical processes. As yet, only bits and pieces of this process are known but enough of a look has been obtained to lead us further in attempting to elucidate all the chemical processes which are involved. What is so spectacular is that, despite the fact that proteins are made up of the same twenty simple amino acids, the tremendous diversity and specificity of function can be achieved simply by variations in the way these amino acids are arranged. The same is true of the nucleic acids. The same few nucleotide units can be reshuffled to give presumably all the variations in the pattern of inheritance which distinguish existing species. Thus is achieved all of the complexity of life from a few fundamental chemical compounds which are not in the least complex. VII It is obvious that the investigation of proteins and nucleic acids has altered and will alter further the way in which we look upon life. Biochemistry has indeed become the key science in the investigation of the living cell. The greater our knowledge concerning the structure and function of the normal organism, the better we shall be able to understand the deviations from normal. These two problems must go hand in hand. Not only does our progress in the study of the normal find application in medicine with its emphasis on the pathological, but medicine contributes richly to the development of our fundamental knowledge. The study of abnormal hemoglobins, mentioned above, has greatly increased our knowledge of normal protein behavior and many, many examples could be cited in which study of disease has called our attention to phenomena of which we were otherwise unaware. In fact, in many cases, it is the only way in which we can approach an understanding of the chemistry and functions of living cells. The living organism operates so smoothly in its chemical transformations and so many of its parts exist in such minute amounts, that we have remained unaware of the existence of constituents and functions until the pathological or abnormal has brought them to our attention. The existence of vitamins and the role of these substances in metabolism were discovered, in large part, by the study of the diseases produced by the
