The rdentrfrcatron of a sedrmentary Csa lsoprenord alkane as 2,6.10,14,18-pentamethyl-7-(3-methylpentyl)nonadecane IS confirmed by syntheses Synthetrc studres conducted by Yon er al ' and more recently by ourselves' have shown that the widely distributed and abundant acyclic C,, and C,, alkenes present m recent sediments are 'I-rsopranylfarnesenes (I,II), although the exact posrtrons of the double bonds m the varrous isomers remains unknown The brologrcal sources of these compounds are probably algaea Co-occurrmg with the C,,
