What is Biochemistry? How does it differ from other sciences like chemistry, biology, molecular biology, and genetics?

                Biochemistry is a branch of science that studies the chemistry of living organisms.  Its main focus is on the chemical reaction, structure, and pathways of bio-molecules in plants, animals, and microorganisms.  These bio-molecules include lipids, carbohydrates, nucleic acids, and amino acids.  The study of biochemistry integrates many aspects of other discipline (like biology, physics, chemistry and organic chemistry) to interpret essential chemical functions within living organism. 

                Biochemistry differs from many other sciences.   In comparison with chemistry and biology, biochemistry is more specific than either of the two and it focuses more on the biological reactions within living organisms.  Chemistry and biology provides a broad range of knowledge that serves as a basis for specialized disciplines like biochemistry. 

                Biochemistry also differs from more specialized studies like genetics and molecular biology.  In genetics, the primary focus is in on the science of genes, gene expression, heredity, and variation among organism.  Genetics essentially examines the results of the chemical reaction of life and not the reaction itself.  In molecular biology, the main focus is on the interaction between cells, organelles, and system in living organisms.  Their studies are centered around the transcription and translation of DNA and RNA where as biochemistry tend to focus more on molecular composition, structure, and functions of these molecules.

                Biochemistry can differ from these sciences but all similar in the fact that they all look to obtain knowledge from the study of life.  These studies are essential in helping with the fight against diseases to improve the quality of life itself.  Many of these different disciplines complement one other and are essential for the advancement of knowledge in science.
