LINAMARIN Structural

What is LINAMARIN?

Description

Linamarin is a glucoside of acetone cyanohydrin found in the leaves and roots of cassava, lima beans, and flax. It is thought to function in the transport of nitrogen from plant leaves to roots in young plants but also serves as a plant defense mechanism. Linamarin is converted to toxic hydrocyanic acid or prussic acid when it comes into contact with linamarase, an enzyme that is released when the cells of cassava roots are ruptured.
