Tryptophan Unit Converter
Tryptophan (Trp) is an essential amino acid necessary for normal growth and nitrogen balance. It serves as a precursor for several biologically important molecules, including serotonin, melatonin, and niacin (Vitamin B3).
Clinically, plasma tryptophan levels are measured as part of an amino acid profile to diagnose metabolic disorders (e.g., Hartnup disease) or monitor nutritional status. This converter facilitates switching between the standard SI molar units (μmol/L) and mass units (mg/dL).
SI Units / Standard
RecommendedMicromoles per liter (Standard for amino acid analysis).

Clinical Context
Reference Ranges (Plasma/Serum):
• Adults: 30 – 80 μmol/L (0.6 – 1.6 mg/dL).
• Infants: Typically 40 – 100 μmol/L.
Conversion Logic:
Molecular Weight of Tryptophan: 204.23 g/mol.
1 mg/dL ≈ 48.96 μmol/L.
1 μmol/L ≈ 0.0204 mg/dL.
