Common NameCarbamic acid
DescriptionCarbamic acid products of several amines, such as beta-N-methylamino-L-alanine (BMAA), ethylenediamine, and L-cysteine have been implicated in toxicity. Studies suggested that a significant portion of amino-compounds in biological samples (that naturally contain CO2/bicarbonate) can be present as a carbamic acid. There has been no obvious species specificity for their formation and no preference for 1 or 2 degree amines. Many biological reactions have also been described in the literature that involve the reaction of CO2 with amino groups of biomolecules. For example, CO2 generated from cellular respiration is expired in part through the reversible formation of a carbamate between CO2 and the -amino groups of the alpha and beta-chains of hemoglobin. The carbamic acid is also a substrate for glucuronidation and results in a stable carbamate glucuronide metabolite. The detection and characterization of these products has been facilitated greatly by the advent of soft ionization mass spectrometry techniques and high field NMR instrumentation.
