Linamarin toxicity

NettetCassava and bamboo shoots, grown primarily in the tropics, contain potentially toxic compounds called cyanogenic glycosides, linamarin and taxiphillin respectively, which break down upon disruption of the plant cells to form hydrogen cyanide. The toxicity of cyanogenic glycosides can be reduced by appropriate preparation of the plant material … Nettet9. mar. 2007 · However, unmetabolized linamarin was found in the urine after oral administration of cassava; thus, we hypothesized that konzo could be caused by direct toxicity of the unmetabolized linamarin that was transferred to the brain and could be transported into neural cells via a glucose transporter.
