Aspartic Acid (Asp) Unit Converter
Aspartic Acid (also known as Aspartate) is a non-essential, acidic alpha-amino acid. It plays a crucial role in the urea cycle and acts as a precursor for the synthesis of other amino acids (including asparagine, arginine, lysine, and methionine), nucleotides, and fumarate in the Krebs cycle. In the central nervous system, aspartate functions as an excitatory neurotransmitter, similar to glutamate.[Image of urea cycle]
Clinically, measuring plasma aspartic acid is part of amino acid analysis used to diagnose inborn errors of metabolism. Elevated levels may be seen in Dicarboxylic Aminoaciduria, a rare transport defect involving glutamate and aspartate. It is also relevant in monitoring patients with neurological disorders due to its excitotoxic potential. This converter allows precise switching between the standard molar unit (µmol/L) and mass-based units like mg/dL.

Clinical Context
Aspartic Acid levels in plasma are typically low compared to other amino acids because it is rapidly metabolized or transported into cells. Reference ranges for adults generally fall between 0 – 6 µmol/L (though some labs quote up to 25 µmol/L depending on the method).
Unlike essential amino acids, low levels are rarely of clinical concern. Elevations are significant when investigating specific transport defects or metabolic acidosis. The conversion factor is based on MW 133.10 g/mol: 1 mg/dL ≈ 75.1 µmol/L.

Frequently Asked Questions & Tips
1 mg/dL = 75.13 µmol/L. This is based on the molecular weight of Aspartic Acid (133.10 g/mol).
Yes, amino acid levels fluctuate with diet. Overnight fasting is usually required for accurate baseline measurement.
