| contents | The distribution of acyclic and cyclic biphytanediols, the putative breakdown products of glycerol dialkyl glycerol tetraethers (GDGTs), was investigated for recent marine sediments from Nankai Trough, offshore Kii Peninsula. The most abundant diol is tricyclic biphytanediol, whose relative abundance is in the range 32–46%. Its carbon skeleton, with two cyclopentane rings and one cyclohexane ring, is the same as would be expected via a crenarchaeol origin. Based on the structure of crenarchaeol, the tricyclic biphytanediol is considered to be derived not only from crenarchaeol but also from other unknown sources. The ring distributions of the biphytanediols are different from those of the biphytanes obtained from intact polar lipids by way of chemical treatment, suggesting that biphytanediols are not solely the diagenetic products of in situ GDGTs. |
