Early steroid sulfurisation in surface sediments of a permanently stratified lake (Ace Lake, Antarctica) Geochimica et Cosmochimica Acta, 2000 (Ref: 9305)
Category 1: Peer-reviewed literature

Surface sediments (0-25 cm) from Ace Lake (eastern Antarctica), a saline euxinic lake, were analyzed to study the early incorporation of reduced inorganic sulfur species into organic matter. The apolar fractions were shown to consist predominantly of dimeric (poly)sulfide linked C-27-C-29 steroids.
