AalphaC  (Synonyms: 2-Amino-α-carboline; AαC)

AalphaC (AαC) is a potential carcinogen with carcinogenic activity. AalphaC is an important biomarker in tobacco smoke and is associated with tobacco smoke exposure. Urinary concentrations of AalphaC are significantly higher in dedicated smokers than in non-smokers, indicating its importance in monitoring tobacco exposure. AalphaC levels increase significantly with increasing serum nicotine levels, indicating its close relationship with tobacco use. In addition, consuming high-temperature cooked beef significantly increases the amount of AalphaC in urine, while consuming vegetables is associated with a decrease in AalphaC concentrations. Smoking half a pack of cigarettes is associated with a significant increase in the amount of AalphaC, which further confirms the biological activity of AalphaC and its association with dietary habits^[1].
