these proteins has been found to bind IgE from sera of allergic patients
(Moreno & Clemente, 2008).
On the other hand, this compact structural feature appears to have
significant beneficial effects. Maintenance of the native conformation
of the inhibitory domain after processing and during gastrointestinal digestion
has been hypothesized to be essential for protective antiproliferative

recovered in an intact form in the liver, kidney and lung after ingestion
