Methionine (Met) Unit Converter
Methionine (Met) is an essential sulfur-containing amino acid that serves as a precursor for crucial molecules, including Cysteine and the dangerous cardiovascular risk factor Homocysteine. Methionine’s metabolic pathway, the methionine cycle, relies heavily on Vitamin B12 and Folate.
Clinically, Methionine levels are monitored in amino acid analysis. High levels can indicate rare metabolic enzyme deficiencies (like Methionine Adenosyltransferase Deficiency). Due to its link with Homocysteine, Methionine metabolism is a key area of study in cardiovascular disease and neurological function. 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 Methionine levels are typically maintained around 20 – 50 µmol/L.
Hyperhomocysteinemia (elevated homocysteine) is the most common pathology linked to Methionine’s pathway, often caused by deficiencies in Folate or Vitamin B12. Extremely high Methionine levels can be seen in rare metabolic diseases. The conversion factor relies on MW 149.21 g/mol: 1 mg/dL ≈ 67.02 µmol/L.

Frequently Asked Questions & Tips
1 mg/dL ≈ 67.02 µmol/L.
Vitamin B12 and Folate are essential cofactors needed to efficiently convert Homocysteine back into Methionine, preventing toxic accumulation of Homocysteine.
