A molecule made of sugars that is one of the body’s main sources of quick energy. Examples include glucose, starch, and glycogen.

A molecule made of amino acids. Proteins help build and repair tissues and can act as enzymes and hormones.

A group of molecules that includes fats and oils. Lipids store long-term energy, protect organs, and are important parts of cell membranes.

A molecule that stores and passes on genetic information. DNA and RNA are nucleic acids.

A small molecule that forms the backbone of fats (triglycerides). It attaches to fatty acids.

Unsaturated triglyceride

A fat contains one or more double bonds in its fatty acid chains. It is usually liquid at room temperature, like many plant oils.

Saturated triglyceride

A fat with no double bonds in its fatty acid chains. It is often solid at room temperature, like butter.

The building block of DNA and RNA. It contains a sugar, phosphate group, and nitrogen-containing base.

A functional group written as –COOH. It is found in fatty acids and amino acids and can act as an acid.

A functional group written as –OH. It is found in molecules such as sugars and alcohols.

A functional group containing phosphorus and oxygen. It is important in DNA, RNA, ATP, and energy transfer.

The cell’s main energy-carrying molecule. Cells use ATP to power many activities.

A functional group written as –NH₂. It is one of the important parts of an amino acid.

Dehydration Synthesis

A reaction that joins smaller molecules together to make a larger molecule by removing water.

A reaction that breaks a larger molecule into smaller molecules by adding water.
