In the Southeast Asia, sodium cyanide (NaCN) is still used as a method for fishing (Mak et al. 2005). In plants, metabolism of cyanides involves β-cyanoalanine formation due to reaction of hydrogen cyanide with cysteine. Then, β-cyanoalanine is transformed into asparagine (Fig. (Fig.5) 5) (ATSDR 1997; Zagrobelny et al. 2004).
