Pyrrolysine (Pyl) Unit Converter
Pyrrolysine (Pyl) is known as the “22nd amino acid.” It is a lysine derivative encoded by the UAG codon in certain methanogenic archaea and bacteria.
While primarily a subject of biochemical research rather than a routine clinical test, accurate unit conversion is essential for preparing reagents, culture media, and analyzing mass spectrometry data. This converter facilitates switching between standard molar concentrations (μmol/L) and mass concentrations (μg/mL, mg/L).
SI / Molar Units
