Life is a chemical process. An understanding of life requires an understanding of the chemical basis of life.The cell being the basic unit of life contain the molecules that are lifeless. But,these inanimate molecules, when organized into living organisms, exhibit extra ordinary attributes. Structural complications, extraction and usage of energy from their environment, capacity to reproduce by the process of self replication and self assembly are some among them. Somewhere in the transition from molecules to cells, they cross the blurry boundary between nonlife and life.
The important foundation for any biologist who wants to understand molecular mechanisms underlying all life is to understand chemistry of biologically important molecules.
Biochemistry is the branch of science which deals with the study of the chemical reactions associated with the biological processes, which in turn relates greatly to the study and understanding of tissues, organs, and whole organisms that is, all of biology.
Here, we focus on the basic laws of chemistry which includes the key properties of matter ,the particles they contain, how they are organized, and how they form chemical bonds with one another.
