Geochemistry

Molecule of the month - 25-Norhopanes

By Paul Farrimond

25-Norhopanes have been reported in biodegraded oils since the late 1970s, and Seifert & Moldowan (1979) proposed that the methyl group at C-25 in the regular hopanes was removed by microbial demethylation associated with the degradation at the oil/water contact of an oil accumulation.
