The levels of the cyanoglucoside linamarin and the activity of its major metabolising enzymes (linamarase, rhodanase and β‐cyanoalanine synthase) were studied in various tissues of the cassava plant. Leaf, stem and rind tissues contained very high levels of both linamarin and linamarase, while lower levels were observed in edible tuber. Rhodanese activity was detected only in leaf tissue. High activity of β‐cyanoalanine synthase in all tissues indicated that the major pathway of cyanoglucoside turnover in cassava was by conversion to asparagine.
