| Term | Definition |
|---|---|
| Organic compound | Molecules built around the element carbon (C) that serve as the main chemical components of living organisms. |
| Macromolecule | Large, complex molecules made by bonding smaller molecules together that play essential roles in the structure, function, and regulation of living organisms. |
| Monomer | Smaller molecules that act as the basic "building blocks" of organic molecules. |
| Polymer | A large molecule made up of linked repeating monomer subunits (such as proteins and nucleic acids). |
| Carbohydrate | A class of macromolecules composed of carbon, hydrogen, and oxygen atoms in a 1:2:1 ratio that serve as a primary source of energy and provide structural support. |
| Monosaccharide | The most basic carbohydrates, consisting of simple sugars like glucose |
| Disaccharide | A sugar consisting of two monosaccharide units joined together, such as sucrose and lactose. |
| Lipid | Molecules such as fats, oils, and waxes that serve as the body's secondary source of energy and act as long-term energy storage. |
| Phospholipid | A type of lipid that makes up the protective outer cell membrane, forming a bilayer that controls what enters and leaves the cell. |
| Protein | A polymer composed of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur, made of amino acid monomers. |
| Amino Acid | The structural monomer building blocks of proteins, composed of an amine group, a carboxyl group, and a variable side chain. |
| Enzyme | Proteins that act as biological catalysts to speed up chemical reactions by breaking down or synthesizing molecules. |
| Nucleic Acid | Biomolecules made of carbon, hydrogen, oxygen, nitrogen, and phosphorus that are responsible for storing and expressing genetic information. |
| Nucleotide | The three-part monomer unit of nucleic acids consisting of a 5-carbon sugar, a phosphate group, and a nitrogenous base. |
