Fatty Acids of Echinoderms: Diversity, Current Applications and Future Opportunities

Area of Science:

• Marine Biology
• Biochemistry
• Pharmacology

Background:

• Echinoderms (Asteroidea, Ophiuroidea, Echinoidea, Holothuroidea, Crinoidea) are marine invertebrates.
• They are commercially valuable and recognized for bioactive metabolites.
• Dietary polyunsaturated fatty acids (PUFAs) are crucial for human health.

Purpose of the Study:

• To review the distribution of fatty acids (FAs) in echinoderm classes.
• To describe the structures, biosynthesis, and bioactivity of echinoderm FAs.
• To emphasize FAs specific to echinoderms and their therapeutic potential.

Main Methods:

• Literature review of accumulated information on echinoderm FAs.
• Analysis of biosynthetic capabilities and feeding habits.
• Compilation of data on FA distribution, structures, and bioactivities.

Main Results:

• Echinoderms possess diverse and unusual FAs, influenced by biosynthesis and diet.
• Certain FAs can serve as chemotaxonomic markers for echinoderm classes.
• Many echinoderm-derived FAs exhibit significant biological activities.

Conclusions:

• Echinoderms are a promising source of essential fatty acids (EFAs) and bioactive compounds.
• Understanding echinoderm FA profiles aids in chemotaxonomy and drug discovery.
• Further research into echinoderm FAs may yield novel therapeutic applications.
