In many biological samples, up to 50% of the nitrogen in human milk is non-protein nitrogen, which is a crucial factor in accurate nutritional assessment. To understand the true protein content of a sample, one must first learn how to calculate non-protein nitrogen (NPN), a process that involves differentiating nitrogen from genuine protein sources versus other nitrogenous compounds.

According to the US EPA, excess nitrogen in water bodies is a major contributor to eutrophication, leading to harmful algal blooms and depleted oxygen levels. Calculating total nitrogen is essential for assessing environmental health, which involves quantifying all nitrogen compounds present in a sample, including organic nitrogen, ammonia, nitrate, and nitrite.
