In their study, the authors stated that the negative effect of the faba bean on birds' performance could be ascribed to various reasons: lower level of some essential amino acids and the presence of
vicine, convicine and tannins as anti-nutritional factors.
(17) Active ingredients include charantin,
vicine, and polypeptide-p.
Its leaves and stems are used to cure diseases due to its hypoglycaemic effect (Fernandes et al., 2007), and contain charantin, a steroidal glycoside;
vicine, a glycoalkaloid and polypeptide 'p', a 166 residue insulinomimetic peptide.
Its chemical composition includes amino acids, alkaloids, lectins, polypeptides, momorcharins, aromatic oils, cytokins, fatty acids,
vicine, sterol glycosides, triterpene glycosides and fixed oils.
The presences of -cyanoalanine,
vicine and convicine among thefactors and substances in raw CVS limit its use in the diets of monogastric animals (Ressler and Takate, 2001; Darre et al., 1998).
Tra le lettere del periodo salzanese, ad esempio, due missive confermano la competenza del futuro riformatore della musica sacra, fornito di un piccolo <<archivio musicale>> e impegnato nella preparazione di messe cantate nelle parrocchie

" It contains at least three active substances with anti- diabetic properties, including charantin, which has been confirmed to have a blood glucose lowering effect,
vicine and an insulin- like compound known as polypeptide- p," Dr Misra says.
Almost unique to faba bean are
vicine and convicine, the causative agents of favism in many human populations.
