Va. Stonik et al., FREE STEROL COMPOSITIONS FROM THE SEA-CUCUMBERS PSEUDOSTICHOPUS-TRACHUS, HOLOTHURIA (MICROTELE) NOBILIS, HOLOTHURIA-SCABRA, TROCHOSTOMA-ORIENTALE AND BATHYPLOTES-NATANS, Comparative biochemistry and physiology. B. Comparative biochemistry, 120(2), 1998, pp. 337-347
Free sterol fractions from the sea cucumbers Pseudostichopus trachus,
Holothuria (Microtele) nobilis, Holothuria scabra, Bathyplotes natans
and Trochostoma orientale have been isolated and studied by HPLC, GLC,
GLC-MS, and NMR methods. About 80 sterols were found and 69 of these
were identified, including-several new and rare ones. Peculiarities of
biosynthesis and metabolism of sterols, as well. as a probable evolut
ionary influence of the presence of membranolytic oligoglycosides on c
ompositions of free sterol fractions in these sea cucumbers, are discu
ssed. (C) 1998 Elsevier Science Inc. All rights reserved.
