The study of the chemical components of living things is known as biochemistry, which is a branch of chemistry. Important chemical processes that occur inside live creatures are the focus of this field of research, which examines interactions between living organic cells and the fluids or matter around them. Structural, biology, Metabolism, and enzymology are the three subfields of biochemistry that further categories the field. Together, towards the end of the 20th century, these three variations adequately explained the life process. Biology is the study of organisms, including their structure, function, and chemical makeup. The human skeleton and muscular system are also examined. Thus, the study of biochemistry is useful for gaining insight into the molecular interactions between and within living organisms. This, in turn, is connected to our knowledge of the anatomy and physiology of cells, tissues, including organs. Molecular biology which focuses on the underlying molecular processes of biological events might be thought of as another definition of biochemistry.
