Biomolecules are organic molecules produced by living organisms, primarily composed of carbon, hydrogen, and oxygen. They include carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are sugars and starches, while lipids encompass fats and oils. Proteins are formed from amino acids, and nucleic acids like DNA and RNA carry genetic information. Key processes include dehydration synthesis, which bonds monomers and releases water, and hydrolysis, which breaks bonds using water. This overview highlights the essential roles of these molecules in life.

Biomolecules • An organic molecule produced by living organisms and made mostly of carbon, hydrogen, and oxygen
Organic molecules • Molecules that contain carbon; the “chemicals of life”
Monomer • Small molecules that are the subunits or building blocks of larger molecules
Polymer • A chain of many monomer molecules bonded together to form a large molecule
Carbohydrates • Group of organic biomolecules made up of C, H and O and the include sugars, starches, and cellulose
Lipids • Group of organic biomolecules made up of C, H and O and that include fats, waxes, oils, phospholipids and steroids.
Proteins • Group of organic biomolecules made up of C, H, O and N that are chains of many amino acids bonded together.
Nucleic Acids • Group of organic biomolecules made up of C, H, O, N, and P and that include DNA and RNA.
Dehydration Synthesis • The creation of a bond between monomers that releases a molecule of water when the bond is created; used to build biomolecules
Hydrolysis • The breaking of the bonds between monomers of a biomolecule using a molecule of water to break the bond.
