Arsenolipids in the green alga Coccomyxa (Trebouxiophyceae, Chlorophyta) Author Řezanka, Tomáš Institute of Microbiology of the Czech Academy of Sciences, Prague, Czech Republic Author Nedbalová, Linda Author Barcytė, Dovilė Author Vítová, Milada Author Sigler, Karel text Phytochemistry 2019 2019-08-31 164 243 251 http://dx.doi.org/10.1016/j.phytochem.2019.05.002 journal article 10.1016/j.phytochem.2019.05.002 1873-3700 10482845 2.1. Fatty acids and lipids from Coccomyxa The fatty acids (FA) in the algal biomass of the genus Coccomyxa identified in the literature were in particular, C16 and C18 FA including eight FA ranging from saturated to triunsaturated ones, i.e. 16:0, 16:1, 16:2, 16:3, 18:0, 18:1, 18:2, 18:3, but not C20 or C22 FA such as arachidonic, eicosapentaenoic or docosahexaenoic FA. The taxonomic classification of the genus Coccomyxa to the class Trebouxiophyceae indicates the possible content of fatty acids ( Lang et al., 2011 ), and other authors dealing with this genus ( Abe et al., 2014 ; Bogen et al., 2013 ; Guschina et al., 2003 ; Guschina and Harwood, 2006 ; Msanne et al., 2012 ) have also presented similar data on FA identified in Coccomyxa algal biomass. Furthermore, common classes of individual lipids were also identified in the biomass of Coccomyxa strains by different authors (see below), Similarly to other representatives of the genus, these included neutral lipids (triacylglycerols (TAG), diacylglycerols (DAG), and sterol esters (SE)) ( Guschina et al., 2003 ) or polar lipids, i.e. phosphatidylcholines (PC), phosphatidylethanolamines (PE), phosphatidylglycerols (PG), phosphatidylserines (PS) ( Kiseleva and Kotlova, 2007 ), phosphatidylinositols (PI) ( Guschina et al., 2003 ), glycolipids - monogalactosyldiacylglycerols (DGGG), diacylglyceryltrimethylhomoserine DGTS) ( Kiseleva and Kotlova, 2007 ), and also sulphoquinovosyl diacylglycerols (SQDG) ( Guschina et al., 2003 ) or trigalactosyldiacylglycerols (TGDG) ( Allen et al., 2017 ).
