Biochemistry
Biochemistry can be defined as the science
concerned with the chemical basis of life
The cell is the structural unit of living systems.
Thus, biochemistry can also be described as the
science concerned with the chemical constituents
of living cells and with the reactions and
processes they undergo.
The Aim of Biochemistry Is to
Describe &Explain, in Molecular
Terms, All Chemical Processes of
Living Cells
Biochemistry describes in molecular terms:
the structures,mechanisms, and chemical
processes shared by all organisms and provides
organizing principles that underlie life in all its
diverse forms, principles we refer to collectively as
the molecular logic of life .
Biochemistry provides important insights and
practical applications in medicine, agriculture,
nutrition, and Industry .

In this plant cell, the nucleus is an organelle containing several types of
supramolecular complexes, including chromosomes. Chromosomes
consist of macromolecules of DNA and many different proteins.
Each type of macromolecule is made up of simple subunits—DNA of
nucleotides (deoxyribonucleotides), for example.
