👉 Non-citable is a scientific term used in biology, chemistry and physics to describe materials that are not able to be converted into chemical energy or stored as matter. These materials can include organic molecules like proteins, carbohydrates, lipids, and nucleic acids, which cannot be broken down by enzymes during cell division or metabolism. These non-citable materials are often found in living organisms, such as plants, algae, fungi, and bacteria. They are not able to undergo chemical reactions that would generate energy
