Definition

ChEBI: Grasshopper ketone is a member of the class of allenes that is cyclohexane substituted by 3-oxobut-1-en-1-ylidene, methyl, hydroxy, hydroxy, methyl and methyl groups at positions 1, 2, 2, 4, 6 and 6, respectively (the 2R,3R,4S-stereoisomer). It is isolated from the grasshopper, Romalea microptera. It has a role as a phytotoxin, a plant metabolite, an algal metabolite, an anti-inflammatory agent, a marine metabolite and an animal metabolite. It is a tertiary allylic alcohol, a member of cyclohexanols, a diol, a methyl ketone, a secondary alcohol, an enone and a member of allenes.
