SUMMARY The total pool of coral lipids consists produced by both the host and its symbiotic dinoflagellates family Symbiodiniaceae. Betaine (BL) are characteristic plasma membranes microalgae. Composition such BL as 1,2‐diacylglyceryl‐3‐ O ‐carboxy‐(hydroxymethyl)‐choline (DGCC) that occur in symbionts may depend on either Symbiodiniaceae species or species. Membrane‐forming DGCC have a zwitterion structure similar to phosphatidylcholine (PC). They can substitute for each other substantial extent, certainly relation membrane functions. In present study, profiles diacyl PC molecular from Acropora sp., Millepora platyphylla Sinularia flexibilis were determined high‐performance liquid chromatography with high‐resolution mass‐spectrometry. Colonies sp. characterized higher contents eicosapentaenoic acid (20:5 n ‐3) C 28 polyunsaturated fatty acids; S. , content palmitic (16:0); M. docosahexaenoic (22:6 ‐3). Although profile corals under study has distinctive features, it shows similarities differences previously studied corals. Probably, symbiont own specific is additionally modified certain way depending environmental conditions created host. Molecular different. most abundant 16:0/22:5 38:4 sp.; 39:5 ; 38:6, 18:0/22:6 . Thus, there no clear evidence any compensation interchangeability between DGCC.
