title: Chlorophyll c(CS-170) isolated from Ostreococcus sp. is [7-methoxycarbonyl-8-vinyl]protochlorophyllide a.
abstract: The controversial molecular identification of the so-called chlorophyll cCS-170 has been settled. Despite its relevance as a potential biomarker in the study of eukaryotic picophytoplankton, the structure of this chlorophyll remained so far uncertain. A full characterization by NMR, UV-vis, and ESI-MS is reported, revealing this chlorophyll as [7-methoxycarbonyl-8-vinyl]-protochlorophyllide a.
