Cannabis Compound Identification
Common Name3-Methyl-2-butenal
Description3-Methyl-2-butenal, also known as senecialdehyde or 3,3-dimethylacrolein, belongs to the class of organic compounds known as enals. These are an alpha,beta-unsaturated aldehyde of general formula RC=C-CH=O in which the aldehydic C=O function is conjugated to a C=C triple bond at the alpha,beta position. 3-Methyl-2-butenal is an extremely weak basic (essentially neutral) compound (based on its pKa). 3-Methyl-2-butenal exists in all living organisms, ranging from bacteria to humans. 3-Methyl-2-butenal is a sweet, almond, and brown tasting compound. Outside of the human body, 3-Methyl-2-butenal has been detected, but not quantified in, several different foods, such as wild celeries, chinese cinnamons, persimmons, cereals and cereal products, and beans. This could make 3-methyl-2-butenal a potential biomarker for the consumption of these foods. An enal consisting of but-2-ene with a methyl substituent at position 3 and an oxo group at position 1. 3-Methyl-2-butenal is expected to be in Cannabis as all living plants are known to produce and metabolize it.

General function:
Involved in oxidoreductase activity
Specific function:
NADPH-dependent reductase with broad substrate specificity. Catalyzes the reduction of a wide variety of carbonyl compounds including quinones, prostaglandins, menadione, plus various xenobiotics. Catalyzes the reduction of the antitumor anthracyclines doxorubicin and daunorubicin to the cardiotoxic compounds doxorubicinol and daunorubicinol. Can convert prostaglandin E2 to prostaglandin F2-alpha. Can bind glutathione, which explains its higher affinity for glutathione-conjugated substrates. Catalyzes the reduction of S-nitrosoglutathione.
