Individual variations in the phospholipid compositions of the organs of marine invertebrates were investigated in the representatives of three phyla: Arthropoda [decapods: Paralithodes camtschaticus (Tilesius, 1815) and Erimacrus isenbeckii (Brandt, 1848)]; Echinodermata [starfishes: Distolasterias nipon (Doderlein, 1902) and Evasterias echinosoma Fisher,(More)
This study examines the crystal-liquid crystal phase transitions of the major phospholipids, phosphatidylcholine (PC) and phosphatidylethanolamine (PE), from muscle tissue of marine fish living at temperatures of 0–4.1°C (the Pacific cod Gadus macrocephalus, banded Irish lord Hemilepidotus gilberti, Pacific halibut Hippoglossus hippoglossus, black edged(More)
The phospholipid compositions of organs and tissues were determined in representatives of two phyla of marine invertebrates: Echinodermata [Asteroidea: Aphelasterias japonica (Bell, 1881), Evasterias echinosoma Fisher, 1926, Distolasterias nipon (Doderlein, 1902), Asterias amurensis Lutken, 1871; Echinoidea: Strongylocentrotus intermedius (A. Agassiz,(More)
This study examines the fatty radical (FR) composition and heat-induced crystalline to liquidcrystalline phase transitions of phosphatidylcholine (PC) and phosphatidylethanolamine (PE) from the gills, hepatopancreas, gonads, and muscle of the tanner crab Chionoecetes bairdi, which was collected in the summer at a near-bottom water temperature of 2.8°C.

To study the adjuvant activity and to optimize tubular immunostimulating complexes (TI complexes) with respect to the soluble antigen, an investigation was performed on cucumariosides and their fractions, i.e., individual triterpene glycosides that were obtained from the holothurian Cucumaria japonica, as well as on phospholipids from the sea urchin(More)
This study examines the molecular species composition and heat-induced crystalline-liquid crystalline phase transitions of phosphatidylcholine (PC) and phosphatidylethanolamine (PE) from the muscle tissues of six species of echinoderms that were collected during the summer: the starfishes Distolasterias nipon and Asterias amurensis, the sea urchin(More)
