Stemar-13-ene
IUPAC 名称
(1R,2S,7S,10S,13R)-2,6,6,12-tetramethyltetracyclo[11.2.1.0¹,¹⁰.0²,⁷]hexadec-11-ene
描述
Stemar-13-ene is a member of the class of compounds known as stemarane diterpenoids. Stemarane diterpenoids are diterpenoids with a structure characterized by a stemarane skeleton. Some characteristics include the bicyclic system C/D that is constituted by a bicyclo[3.2.1]octane fused to the bicyclic A/B system in a different fashion with respect to other tetracyclic diterpenes possessing the bicyclo[3.2.1]octane system. Moreover, the two contiguous quaternary carbon atoms, C(9) and C(10), are present, the former being a spirocyclic atom. Oxygenation can happen at positions C(2), C(7), C(13), C(17), C(18), and C(19). Thus, stemar-13-ene is considered to be an isoprenoid lipid molecule. Stemar-13-ene can be found in rice, which makes stemar-13-ene a potential biomarker for the consumption of this food product.
