Sesquiterpenoids are terpenes with three consecutive isoprene units. Gamma-atlantone is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Gamma-atlantone can be found in turmeric, which makes gamma-atlantone a potential biomarker for the consumption of this food product. gamma-(E)-Atlantone C15H22O 218.3346 218.167065326 2-methyl-6-[(1Z)-4-methylcyclohex-3-en-1-ylidene]hept-2-en-4-one 2-methyl-6-[(1Z)-4-methylcyclohex-3-en-1-ylidene]hept-2-en-4-one 108549-47-9 CC(C)=CC(=O)C\C(C)=C1\CCC(C)=CC1 InChI=1S/C15H22O/c1-11(2)9-15(16)10-13(4)14-7-5-12(3)6-8-14/h5,9H,6-8,10H2,1-4H3/b14-13+ QEAHSEZXAQIWSW-BUHFOSPRSA-N belongs to the class of organic compounds known as sesquiterpenoids.
