NMTCA  (Synonyms: NMTPRO; N-Nitroso-2-methylthiazolidine 4-carboxylic acid; N-nitrosomethylthioproline)

NMTCA (NMTPRO) is a sulfur-containing N-nitrosamino acid. NMTCA can be used as an indicator of endogenous nitrosation by gas chromatography-thermalenergyanalysis^[1][2].

Smoking is one of the important factors in determining the amounts of NTCA and NMTCA in human urine^[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
