Abstract

A novel polar neutral lipid was isolated from thermoacidophilic archaeon, Metallosphaera sedula TA-2. The structure of this lipid was characterized to be 1,1′-bis[D-glucosyl-(β1-3)-D-galactosyl-(β1)]-sn-caldarchaeol by mass spectrometory, NMR analysis, chromatographilical profiles of the lipid and its degradation products.
