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.

Molecular biology concerns the molecular basis of biological activity between biomolecules in the various systems of a cell, including the interactions between DNA, RNA, and proteins and their biosynthesis, as well as the regulation of these interactions.

Writing in Nature in 1961, William Astbury described molecular biology as:

Applied science is a discipline of science that applies existing scientific knowledge to develop more practical applications, like technology or inventions.

A reagent is a substance or compound added to a system to cause a chemical reaction, or added to test if a reaction occurs.

The terms reactant and reagent are often used interchangeably—however, a reactant is more specifically a substance consumed in the course of a chemical reaction.

Solvents, though involved in the reaction, are usually not called reactants.

Similarly, catalysts are not consumed by the reaction, so they are not reactants.

In biochemistry, especially in connection with enzyme-catalyzed reactions, the reactants are commonly called substrates.
