Most notably, they are produced by Emiliania huxleyi (Volkman et al. 1980), which is found throughout the modern ocean (Westbroek et al. H. Freeman and M. 2. The molecular structures of C37:2 and C37:3 alkenones. phyrocapsa oceanica (Volkman et al. 1995). The most commonly observed structures are the C37, C38, and C39 methyl and ethyl ketones (de Leeuw et al. , Brassell et al. 1986; Reviewed by Brassell 1993; Sachs and Lehman 1999). Rechka and Maxwell (1988a, b) confirmed the trans configuration of the double bonds and suggested this property makes them more resistant to biological degradation.
