WebThe coincidence of high abundances of C24-C30 tetracyclic terpanes(17,21-secohopanes) and regular hopanes, together with high abundance of C22-C27 sterenes and the absence of common regular C27-C29 steranes, also suggests the unusual C22-C27 sterenes, similarly to C24-C30 tetracyclic terpanes, might be product of microbial transformation in … Webtified in the source rocks and the oil, the methyl group lost at A fragment should be the angle methyl group at C-10 position, but the position of the lost methyl group at B fragment depends fishing tn

The most common member, 28,30-bisnorhopane, can be found in high concentrations in petroleum source rocks, most notably the … See more 28,30-bisnorhopane exists in three epimers: 17α,18α21β(H), 17β,18α,21α(H), and 17β,18α,21β(H). During GC-MS, the three epimers coelute at the same time and are nearly indistinguishable. However, mass spectral fragmentation … See more The exact origins of 28,30-bisnorhopane have not been conclusively established, however, there are analytical implications towards generation from chemoautotrophic bacteria.
