Biochemistry can be defined as the study of chemical compounds that occur in living organisms (plants and animals), and the vital processes that occur in their metabolism and catabolism. Biochemistry combines elements from both biology and chemistry and it involves the study of large biological molecules such as proteins, carbohydrates and lipids, nucleic acids and enzymes in terms of their interactions, functions and structures. Biochemistry can be divided into three disciplines which are; protein science, molecular genetics, and metabolism.
