Silkworms have a unique ability to eat toxic mulberry leaves without
feeling ill, and researchers have come one step closer to understanding
why: silkworms contain a special digestive enzyme that is not affected
by mulberry's toxic chemicals.
leaves contain an extremely high amount of alkaloids that inhibit
enzymes that break down sucrose (sugar), and thus are potentially quite
toxic. However, one type of sucrase called beta-fructofuranosidase is
not affected by these alkaloids.
