Biochemistry is a branch which is concerned with the chemistry of the biological processes. The study of biochemistry agreements with the chemical combinations and reactions which take place in biological processes such as growth, metabolism, reproduction, heredity etc., as well as the effect of the environment on living organisms. Studying structures and functions of enzymes, protiens, carbohydrates, fats, process of metabolism and the molecular basis of the action of genes also form a part of biochemistry. Advances made in biochemistry has made significant contributions towards elucidation and understanding of the DNA structure.
Biochemistry, sometimes called biological chemistry, 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. Over the last decades of the 20th century, biochemistry has become so successful at explaining living processes that now almost all areas of the life sciences from botany to medicine to genetics are engaged in biochemical research. Today, the main focus of pure biochemistry is on 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 tissues, organs, and whole organisms—that is, all of biology.
