Very-long-chain iso and anteiso branched fatty acids in N-acylphosphatidylethanolamines from a natural cyanobacterial mat of Calothrix sp.
A combination of TLC, ESI-MS/MS and GC-MS was used to identify unusual molecular species of N-acylphosphatidylethanolamines containing very-long-chain anteiso branched fatty acids (VLCFAs) from Calothrix sp. collected in Antarctica and determine their component VLCFA up to 33-methyltetratriacontanoic acid as picolinyl ester derivatives using GC-MS.
