Tetraether lipids of Methanospirillum hungatei with head groups consisting of phospho-N,N-dimethylaminopentanetetrol, phospho-N,N,N-trimethylaminopentanetetrol, and carbohydrates.
Acyclic, standard tetraether and diether lipids each account for about 50% of the total ether lipids found in Methanospirillum hungatei. Sixteen ether lipids were purified and defined according to relative weight percentage and staining reactions on thin-layer plates. Structures were elucidated for six previously uncharacterized tetraether lipids. Four of… (More)
