It was considered that an acidic species can intervene in the decomposition process of urea by expediting the isomerization process of the cyanic acid form into the isocyanic acid form (Eq.
However, gaseous isocyanic acid is stable in the presence of water vapor for several seconds and at temperatures up to 1000 K.
Allen, "Characterization of the X 1A' state of isocyanic acid," The Journal of Chemical Physics, vol.
The expected mass of the neutral loss of isocyanic acid was determined by subtracting the product of a 43 Da loss divided by the peptide charge from the observed mass of the peptide sequence [37].
New device measures atmospheric isocyanic acid. Environ Health Perspect 119(8):A338 (2011); http://dx.doi.org/10.1289/ehp.119-a338a.
Scientists in the US studied exposure levels of isocyanic acid. Lead researcher Dr Jim Roberts, from the National Oceanic and Atmospheric Administration in Boulder, Colorado, said: "We found isocyanic acid in a number of places, from air in downtown Los Angeles and air downwind of a Colorado wildfire, to cigarette smoke.
With 1:2 ratio of choline chloride: urea, the by-products include by-products in case of 1:1 ratio and isocyanic acid. This is the factor which changes products' comeback initial state and crystallize at room temperature.
The first step consists of the thermolysis of urea into isocyanic acid and ammonia due to the heat (Eq.
Carbamylation of proteins results from nonenzymatic chemical modification by isocyanic acid derived from urea and an alternative route, the MPO-catalyzed oxidation of thiocyanate.
Carbamylation results from the covalent binding of isocyanic acid to proteins and is one of the nonenzymatic reactions involved in protein molecular ageing (i.e., glycation, oxidation, or carbonylation).
Isocyanic acid in the atmosphere and its possible link to smoke-related health effects.
Isocyanic acid (chemically HNCO), a contaminant linked to cataracts and heart disease, has for the first time been measured in the atmosphere.
Another nonenzymatic posttranslational modification of proteins is carbamylation, which corresponds to the binding of isocyanic acid to amino groups.
