👉 Nonnitric is a term used in the fields of chemistry and biology to describe substances that do not contain nitrogen. These substances are usually found in organic compounds, such as proteins, carbohydrates, lipids, and other organic molecules. Nonnitric substances typically have a high melting point, which means they can be solid at room temperature or below. They also often show unusual chemical properties, such as having low boiling points, poor reactivity with acids, and sometimes being toxic to humans.
