Fig. 1. Fecal β-glucosidase activity of 100 Koreans. (A) Distribution of β-glucosidase activity. (B) Average β-glucosidase activity. (C) Comparison of β-glucosidase activity between male (closed circle) and female (open circle), or between ages. The β-glucosidase activity was measured using p-nitrophenyl-β-D-glucopyranoside (PNG) as a subtrate.
