At its core, chemical studies encompass five main branches analytical, organic, inorganic, physical, and biochemistry. Analytical chemistry focuses on the identification and quantification of chemical components, while organic chemistry delves into the chemistry of carbon compounds, the building blocks of life. Inorganic chemistry, on the other hand, investigates the behavior of elements and their compounds, excluding carbon compounds. Physical chemistry merges principles from physics to understand the fundamental laws governing chemical reactions. Lastly, biochemistry explores the chemical processes within living organisms, providing a molecular blueprint for life.
