Isolation and Structure of a Galactocerebroside from the Sea Cucumber Bohadschia argus

Fatty acid composition of the edible sea cucumber Athyonidium chilensis

“…These 2-hydroxy fatty acids are characteristic of echinoderm sphingolipids and have previously been identified in the glucosylceramides of the starfishes Allostichaster inaequalis (Dı´az de Vivar et al, 2002) and Cosmasterias lurida (Maier, Kuriss, & Seldes, 1998) and in the galacto-and glucosylceramides of the holothurians Bohadschia argus (Ikeda et al, 2009) and Stichopus japonicus (Kisa, Yamada, Kaneko, Inagaki, & Higuchi, 2005). Heptadecanal (17 : 0) was identified in low amounts in tubules (0.70-1.07%), internal organs (0.81-0.90%) and body wall (0.61-0.75%) PL and phospholipids.…”

Isolation and Anti-Fatty Liver Activity of a Novel Cerebroside from the Sea CucumberAcaudina molpadioides

“…[1][2][3][4] Analysis of the chemical composition of AMC-2. AMC-2 (2.0 mg) was heated with 10% HCl in MeOH (1 mL) at 70 C for 18h.…”

“…GSLs are classified into cerebrosides, sulfatides, ceramide oligohexosides, globosides, and gangliosides based on the constituent sugars. Most of the cerebroside constituents of the sea cucumber are the same glucocerebrosides (GluCer) as in other animals, [1][2][3][4] except for a few constituents. 5) Cerebrosides from sea cucumber are composed of three different structural units: a polar head group (monosaccarides, such as glucose or galactose), an amide-linked fatty acid, and a long-chain base (LCB) which is also called a sphingoid base.…”

Glycolipids from Marine Invertebrates

“…In addition to the glucocerebrosides identified in lipids of the sea cucumber Bohadschia argus, a new galactosylceramide, BAC-4-4a, was obtained from its parent molecular species (Ikeda et al, 2009). This contained a 2-hydroxy D15(Z)-C 24:1 acid, and normal and iso-saturated sphingoid bases.…”
