Common Name

ent-Cassa-12,15-diene

Description

Ent-cassa-12,15-diene is a member of the class of compounds known as isocopalane and spongiane diterpenoids. Isocopalane and spongiane diterpenoids are diterpenoids with a structure based on the isocopalane (Tetradecahydro-1,1,4a,7,8,8a-hexamethylphenanthrene) or the 15,16-epoxyisocopalane skeleton. Thus, ent-cassa-12,15-diene is considered to be an isoprenoid lipid molecule. Ent-cassa-12,15-diene can be found in rice, which makes ent-cassa-12,15-diene a potential biomarker for the consumption of this food product.
