  What Are Biomolecules? Biomolecules are the natural chemical compounds that living organisms are made of. They are produced inside cells and are essential for life because they: Build the structure of cells and tissues Store and transfer genetic information Provide energy Control chemical reactions in the body Biomolecules are mainly made from six key elements: carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulphur. Major Types of Biomolecules Carbohydrates – provide quick energy Proteins – build body structures and act as enzymes Lipids – store energy and form cell membrane. Nucleic acids – DNA and RNA, which store genetic information Conjugated molecules – combinations like glycoproteins and lipoproteins In short: > Biomolecules are the chemical substances that make life possible. Introduction to Biochemistry Biochemistry is the branch of biology that studies the chemical basis of life. It focuses on the structure, composition, and reactions of the molecules found insid...
