Some components in SC such as cerebrosides (Kawai and Ikeda, 1985), SPG (Kumari et al.
Cerebrosides are present in SC and they are able to block calcium-activated chloride channels in rat pulmonary artery smooth muscle cells (Gao et al.
Amongst the lipids, it is usually the phospholids that can be considered as micronutrients but one should also consider free fatty acids, cerebrosides
and cholesterol, and there are some minor fatty acids in the triglycerides that are considered to be important.
Nonetheless, polar steroids are proved to be an important natural product isolated from brittle stars which are responsible for their cytotoxicity, terpenes, naphthoquinones, phenylpropanoids, carotenoids and cerebrosides
have been isolated from brittle stars and might have pharmacological activities (13).
Ali, Longifoside-A and -B: Two New Cerebrosides
from Mentha longifolia (Lamiaceae), Nat.
Antibacterial and xanthine oxidase inhibitory cerebrosides
from Fusarium sp IFB-121, an endophytic fungus in Quercus variabilis.
Recent research revealed that certain sphingolipids, including cerebrosides
and ceramides, form tubular microstructures upon hydration.
Furthermore, the existence of cerebrosides
and alkaloids isolated from brittle star has been reported but no reports related to extraction of polysaccharide from brittle star exist (12).
The concentration of cerebrosides
and sulfatides is decreased during ischemia (Mikulas et al.
