Biochemistry allows us to understand how various chemical processes in all
living organisms interact and function to support life. It covers a wider range of
scientific disciplines, which are sub-categorised into different branches. In this unit, the
importance of biochemistry in medicine, health sectors, nutrition, and the living system
has been discussed in detail. It also helps to understand biological phenomena of the
environment and its conversation, genetic manipulations of genes via recombinant
DNA technology and gene sequencing via human genome project. The knowledge of
biochemistry has advanced tremendously and in forthcoming years, it has a potential
role in unravelling the mystery of life processes.
