Crenarchaeol

The basic structure and stereochemistry of the characteristic glycerol dibiphytanyl glycerol tetraether (GDGT) membrane lipid of cosmopolitan pelagic crenarchaeota has been identified by high field two-dimensional (2D)-NMR techniques. It contains one cyclohexane and four cyclopentane rings formed by internal cyclisation of the biphytanyl chains. Its structure is similar of by crenarchaeota the cyclohexane the of and pelagic crenarchaeota The the membrane of cyclopentane the the of the the of the membrane by one of the biphytanyl by the of cyclohexane the characteristic the cyclopentane membrane by crenarchaeota membrane high The basic structure and stereochemistry of the characteristic glycerol dibiphytanyl…
