Plant Biochemistry is not only an important field of basic science explaining the molecular function of a plant but is also an applied science that is in the position to contribute to the solution of agricultural and pharmaceutical problems. Plant Biochemistry is the study of chemical processes within and relating to living organisms. By controlling information flow through biochemical signaling and the flow of chemical energy through metabolism, biochemical processes give rise to the complexity of life. Bbiochemistry has become so successful at explaining living processes that now almost all areas of the life sciences from botany to medicine are engaged in biochemical research. Today the main focus of Plant Biochemistry is in understanding how biological molecules give rise to the processes that occur within living cells, which in turn relates greatly to the study and understanding of whole organisms.
