“…The amino acid profile of the studied species agrees with the reported in literature for the same species (Sicuro et al 2012) and also for different sea cucumbers genera, such as Cucumaria and Actinopygia (Zhong et al 2007;Wen et al 2010). The richness of glycine is highly relevant, since the intake of food rich in that amino acid is associated with the reduction in total cholesterol levels in serum (Aljawad et al 1991;Ikeda et al 1993). The lysine/arginine ratios are usually linked to hypocholesterolemic effects (Bordbar et al 2011) and were lower than those usually described in different sea cucumbers species (Bordbar et al 2011).…”

This work makes a comparative evaluation of the biochemical profile of three sea commercial cucumber species (Holothuria mammata, H. polii and H. tubulosa) caught from different locations of the Mediterranean Sea (SE Spain). All species had high levels of moisture (from 73.6% in H. mammata to 81.2% in H. tubulosa), crude ash (from 9.61% in H. mammata to 14.7% in H. tubulosa) and protein (3.01% in H. tubulosa to 11.1% in H. mammata). They also had a low fat content, from 0.21% in H. tubulosa to 0.55% in H. mammata. Holothuria polii had intermediate values between the other two species, for all considered variables. All species had adequate protein/lipid ratios (H. mammata, 20:1; H. polii, 23:1; H. tubulosa, 14:1) and low lipid levels, enriched in omega-3 polyunsaturated fatty acids, especially arachidonic acid. The fatty acid profile suggests that H. polii is feeding on sediments more influenced by terrestrial inputs than the remaining species. Holothuria mammata and H. tubulosa are feeding on marine food sources mainly, but also with some terrestrial influence. The most abundant amino acids detected were alanine, arginine, glutamic acid, and glycine. All species had similar contents of essential amino acids (EAA) and ratios of EAA/non-essential amino acids. Holothuria tubulosa had a high content of toxic metals including Cr, Pb and Ni. This work highlights differences in compositional characteristics between different species of the same genus (Holothuria) from different locations.

“…It has been found also that glycine reduced serum total cholesterol level (Aljawad et al, 1991;Ikeda et al, 1993). The present result agrees with that of Wen et al (2010) who showed that glycine was abundant in Stichopus herrmanni, Thelenota ananas, Thelenota anax, Holothuria fuscogilva, Holothuria fuscopunctata, Actinopyga caerulea and Bohadschia argus.…”

Functional food that contains biologically-active compounds is an important source for prevention, management and treatment of chronic diseases in the modern age. The present work showed the quality of some Egyptian sea cucumbers to encourage Egyptian natives using them as an alternative food. The present work investigated the morphometric parameters, the proximate chemical composition, the amino acids and fatty acid profiles of Actinopyga mauritiana, Holothuria scarba, Bohadschia marmorata and Holothuria leucospilota. The results showed that Actinopyga mauritiana had the highest length, width, weight, and body wall thickness. All the investigated sea cucumbers had high content of protein (43.23 to 48.27%), carbohydrates (44.62 to 48.56%) and very low content of fats (4.6 to 5.66%). Among the investigated specimens A. mauritiana showed the highest percentage of total protein (48.27%), Holothuria leucospilota showed the lowest level of total lipids (4.6%), while Holothuria scarba showed the highest percentage of carbohydrates (48.65%). Glycine was the most abundant amino acids in all studied sea cucumbers (18.38 to 19.172 g/100 g) and constituted 37 to 39% of the total amino acids. Lycine: argignin ratio was low in H. scarba, H. leucospilota and B. marmorata (0.410, 0.428 and 0.9, respectively) while was higher in A. mauritiana (3.56). Myristic acid was the most abundant saturated fatty acid (SFA) in all studied sea cucumbers (19.789 to 37.036 %) followed by palmitic acid (16.93 to 16.926%). Among the unsaturated fatty acid (UFA) oleic and linoelaidic acids were the most abundant acids in all investigated cucumbers. On the other side linoleic acid (omega 6) was abundant in H. scarba and constituted 26% of the UFA. In conclusion, all investigated sea cucumbers had high protein and low fat contents and the bioactive compounds in the sea cucumbers describe its efficacy in tissue regeneration and inflammatory diseases.
