What is biochemistry?

   Biochemistry is the field of study concerning the composition, structure, function and chemical reactions of the substances found within living organisms. It is a combination of organic, inorganic and physical chemistry. This field of study combines different sciences to derive the sources of energy in which living things can work. There is overlap between biochemistry and the other sciences, such as biology, genetics and molecular biology. 

   In comparison to genetics, biochemistry looks further in depth to the chemical basis of heredity rather than the proteins, amino acids and traits studied in genetics. In molecular biology, the essential macromolecules are studied to understand life processes of cellular respiration, excretion and reproduction. Biology appears to be a more generalized study of life. The concepts of evolution, origin, cell structures, mitosis, meiosis, interactions and relationships are some of the few areas considered by biologists. In other words, the material studied in biochemistry stems from previous knowledge learned throughout prior sciences courses and combines them for a new understanding of metabolic pathways of life.
