What is Biochemistry?

Biochemistry is the science of living organisms. This field of study includes many different topics like the structure of proteins, carbohydrates, and lipids; the energy metabolism of cells; the formation of biological macromolecules, such as RNA and DNA; the reproduction of cells and organisms; and the control of biological processes by chemical signals. In addition to the basics of science, a basic knowledge of chemistry is necessary to understand the topics of biochemistry.

The structure of proteins

Proteins are very important and play an essential role in the life of an organism. They are the building blocks of all living things. Proteins are composed of different types of groups of atoms called amino acids. Each of these amino acids has a specific structure. The structure of a protein determines its function. The different types of proteins are divided into five groups based on their functions.

The function of a protein

All living things are composed of cells. The cell is the smallest unit of life. It is divided into two parts, the cytoplasm and the nucleus. The cytoplasm is the part that contains the cell's machinery and resources for growth and reproduction. The nucleus is the part that contains the DNA. The DNA is the genetic material that is responsible for the production of new proteins and for the modification of genes.
