Relative abundance (RA) of molecular species of betaine lipids identified in F. vesiculosus collected in winter (February) and spring (May), determined by HILIC LC–MS: (a) DGTS; (b) MGTS; (c) DGTA; (d) MGTA molecular species. Numbers in parentheses (C:N) indicate the number of carbon atoms (C) and double bonds (N) in the fatty acid side chains. The species with higher relative abundance were DGTS (32:1), MGTS (16:0), DGTA (32:1), DGTA (32:2), MGTA(18:1), and MGTA (18:2).
