Substances made of atoms that are found in living things, including proteins, nucleic acids, and carbohydrates.
Proteins and DNA are examples of biomolecules essential for life.
Biomolecule is formed from "bio-" (from Greek "bios", meaning life) and "molecule" (from Latin "molecula", meaning a small mass or particle). The word refers to a small particle that is essential for life, such as proteins, nucleic acids, carbohydrates, and lipids.
Think of 'bio-' meaning life, and 'molecule' as a small particle — together they describe a small particle that is essential for life.
