It's a protein called lectin
A Lectin is any protein which specifically interacts with sugar molecules
(carbohydrates) and are found in a variety of species from insects to man.
They serve many different biological functions from the regulation of cell
adhesion to glycoprotein synthesis and the control of protein levels in the
blood. Lectins are also known to play important roles in the immune system by
recognising carbohydrates found exclusively on patho

I am in a glycobiology lab and happened to use pea lectin
in an experiment recently. My feeling is that, though lectin will
cause health problem, they have generally minor effects. Lectins
with different recognition specificity are found in a wide range
of crops other than beans , like peanuts,soybean, wheat, pea...
The toxic stuff in the raw beans people are talking about is actually
cyanogen compounds (not proteins) in the beans. These compounds are
more dangerous than lectins. Fortunat
