Structures and profiles of novel sulfur-linked chlorophyll derivatives in an Antarctic lake sediment
High performance liquid chromatography-mass spectrometry has permitted the identification of a homologous series of novel alkylsulfide derivatives of chlorophyll a containing between one and five carbon atoms, in sediment from a coastal Antarctic lake. The sulfur-containing compounds are present in...
