Amygdalin, Amygdaline, a-mig′da-lin, n. a crystalline principle existing in the kernel of bitter almonds.
Emulsine has the property of being able to hydrolyse the glucoside amygdalin to glucose, benzaldehyde, and hydrocyanic acid.
Amygdalin was first discovered in 1830, and was one of the first substances to be recognized as a glucoside.
In the amygdalin molecule, it exists in the dextro form, which has been named "prunasin."
It is, therefore, similar to amygdalin, except that one glucose molecule is replaced by arabinose.
