Biochemistry is at the interface of Chemistry and Biology, and explores the chemical processes within and related to living organisms. It is an experimental discipline that uses chemical knowledge and techniques to understand and solve biological problems. ?Biochemistry focuses on cellular processes at the molecular level, involving the study of components like proteins, lipids and organelles. Biochemistry is also used to provide insights into questions such as how cells communicate with each other, or integrate together to promote growth or fight illness.
