Chemical Information

FooDB Name

(E)-2-Octenal

Description

2-octenal, also known as 2-octenal, (Z)-isomer, is a member of the class of compounds known as medium-chain aldehydes. Medium-chain aldehydes are an aldehyde with a chain length containing between 6 and 12 carbon atoms. 2-octenal is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 2-octenal has a fatty and green taste. 2-octenal can be found primarily in blood. 2-octenal is a non-carcinogenic (not listed by IARC) potentially toxic compound. As a uremic toxin, this compound can cause uremic syndrome. Uremic syndrome may affect any part of the body and can cause nausea, vomiting, loss of appetite, and weight loss. It can also cause changes in mental status, such as confusion, reduced awareness, agitation, psychosis, seizures, and coma. Abnormal bleeding, such as bleeding spontaneously or profusely from a very minor injury can also occur. Heart problems, such as an irregular heartbeat, inflammation in the sac that surrounds the heart (pericarditis), and increased pressure on the heart can be seen in patients with uremic syndrome. Shortness of breath from fluid buildup in the space between the lungs and the chest wall (pleural effusion) can also be present (T3DB).
