Glutamine (Gln) Unit Converter
Glutamine is the most abundant free amino acid in the human body. It is critical for nitrogen transport, serves as a major energy source for immune and gut cells, and plays a vital role in detoxifying toxic ammonia by synthesizing it from Glutamic Acid and Ammonia.
Clinically, elevated plasma Glutamine levels are a sensitive marker for Urea Cycle Disorders (UCDs), as the body aggressively synthesizes glutamine to safely sequester excess ammonia, a process that relies heavily on Glutamine. High levels also correlate with severe sepsis and metabolic stress. This converter facilitates accurate switching between the conventional mass unit (mg/dL) and the International SI unit (µmol/L).

Clinical Context
Reference Range (Fasting): Plasma Glutamine levels are high, typically maintained around 400–800 µmol/L.
Hyperammonemia (high ammonia) is often accompanied by elevated Glutamine, as the body uses Glutamine synthesis as a temporary detoxification method. This is a critical finding in UCDs and severe liver failure. The conversion factor relies on MW 146.15 g/mol: 1 mg/dL ≈ 68.42 µmol/L.

Frequently Asked Questions & Tips
1 mg/dL ≈ 68.42 µmol/L.
Yes. Glutamine is essential for gut function; blood levels can fluctuate rapidly after a meal, making fasting crucial for diagnostic baseline measurements.
