Nitrogen-bearing is a commonly used term in chemistry and biology to describe substances that contain nitrogen. However, there are several synonyms that can be used to describe this type of substance. Some of the synonyms for nitrogen-bearing include nitrogenous, azotic, and nitrous. Nitrogenous refers to any compound that contains nitrogen, while azotic is a rare term used to describe nitrogen in its pure form. Nitrous, on the other hand, refers specifically to compounds that contain nitrogen and oxygen. Using these synonyms can help make scientific writing more concise and varied, while still conveying the intended meaning.
