Biochemistry is the study of the structure and function of biological
molecules such as proteins, nucleic acids, carbohydrates and lipids.
Biochemistry is also used to describe techniques suited to understanding the
interactions and functions of biological molecules and it is a laboratory based
science that brings together biology and chemistry. By using chemical knowledge
and techniques, biochemists can understand and solve biological problems.
Biochemistry focuses on processes happening at a molecular level and it focuses
on what’s happening inside our cells. It also looks at how cells communicate
with each other, for example during growth or fighting illness. Medicine is a
broad category but relates to biochemistry on many levels. Doctors and nurses
give drugs to patients to help cure a disease or prevent it. This is since when
that drug is added to the human system, it alters how other chemicals in the
body function, resulting in disease prevention or recovery.
