) is a dense, rounded, deciduous tree or large multi-stemmed shrub which are commercially grown for their edible nuts. It is grown worldwide although primarily native to western Asia.
appears similar to the peach tree. The fruits and wilting leaves of the tree contain cyanogenic glycosides, which release toxic hydrogen cyanide when chewed.
The bitterness of almond is determined by the amount of the cyanogenic diglucoside amygdalin in the plant tissue. Diglucoside amygdalin is a cyanogenic glucoside, which if disturbed, causes the plant the respond with an immediate chemical defense which causes the release of Glc, an aldehyde or ketone, and HCN, a toxic substance to animals.
