“…Our results for molluscs differ from those found by Srilatha et al (2013), who reported moderate concentrations of arginine and high concentrations of lysine, glycine, and phenilalanine in the clam Meretix casta from the southeast coast of India. The octopus E. massyae showed similarities in its amino acid composition in comparison to some species of fish analyzed by Diniz et al (2013), such as the high concentrations of lysine and leucine.…”

“…However, it is possible to compare data on its chemical composition with those of other bivalve species. For instance, the protein content recorded by us in I. bicolor is similar and it is within the range of temporal variation found by Srilatha et al (2013) for the clam, Meretrix casta, sampled in southern India (30-45% dw). The protein content of I. bicolor is also similar to those reported for edible bivalves, such as Mytilus galloprovincialis (Fuentes et al, 2009) and Crassostrea rhizophorae (Lira et al, 2013), among others.…”

ABSTRACT. The chemical profiles of Desmapsamma anchorata, Hymeniacidon heliophila (Porifera), Bunodosoma caissarum, Renilla muelleri (Cnidaria), Aplysia brasiliana, Eledone massyae, Isognomon bicolor (Mollusca), Echinaster brasiliensis, Echinometra lucunter, Holothuria grisea, Lytechinus variegatus (Echinodermata), and Phallusia nigra (Chordata) were determined. Hydrosoluble protein was the most abundant class of substances for all species, except for the ascidian Phallusia nigra, in which the carbohydrate content was higher. The percentages of hydrosoluble protein (dry weight, dw) varied widely among the invertebrates, ranging from 5.88% (R. muelleri) to 47.6% (Eledone massyae) of the dw .The carbohydrate content fluctuated from 1.3% (R. muelleri) to 18.4% (Aplysia brasiliana) of the dw. For most of the species, lipid was the second most abundant class of substances, varying from 2.8% (R. muelleri) to 25.3% (Echinaster brasiliensis) of the dw. Wide variations were also found for the invertebrates nitrogen content, with the lowest value recorded in the cnidarian R. muelleri (2.02% of the dw) and the highest in the molluscan E. massyae (12.7% of the dw). The phosphorus content of the dw varyed from 0.24% (R. muelleri) to 1.16% (E. massyae). The amino acid composition varied largely among the species, but for most of the species glycine, arginine, glutamic acid, and aspartic acid were the most abundant amino acids, with histidine and tyrosine among the less abundant amino acids. The actual content of total protein in the samples was calculated by the sum of amino acid residues, establishing dw values that fluctuated from 11.1% (R. muelleri) to 66.7% (E. massyae). The proteinaceous nitrogen content was high in all species, with an average value of 97.3% of the total nitrogen. From data of total amino acid residues and total nitrogen, specific nitrogen-to-protein conversion factors were calculated for each species. The nitrogen-to-protein conversion factors ranged from 5.10 to 6.15, with an overall average of 5.45. The use of the specific nitrogen-to-protein conversion factors established here is recommended, since it would yield more accurate determinations of total protein in the species tested in this study.

Noble scallop Chlamys nobilis is an economically important edible marine bivalve that display polymorphism in shells and flesh colors. The present study was carried out to investigate whether there is a difference in amino acid (AA) content and composition between the two polymorphic scallops. The AA content and compositions of the whole edible flesh, adductor, and mantle were extracted and analyzed using high‐performance liquid chromatography. The results of this study revealed that golden and brown scallops have a similar AA composition, but distinctive content, and the differences in AA contents are obvious in adductor. Moreover, regardless of shells and flesh color, both noble scallops have high quantity and high‐quality proteins that are easily digested and contain dietary essential AAs in quantities corresponding to human requirements. The present study demonstrates for the first time that polymorphisms in aquatic animals have different AA contents but similar composition. Practical applications The noble scallop is an economically important edible marine bivalve that is widely distributed in Japan, Indonesia, and the Southern Sea of China. They have been widely cultivated in South China since the 1980s. The present study not only provides knowledge of the AA composition of scallops which serves as a basis for establishing their potential nutritive value, but also provides the first reference for AA content and compositions of polymorphism.

Turban snails (family Turbinidae) are gastropod molluscs that are harvested for human consumption yet little is known about the nutritional properties of these snails, particularly from Australian waters. This study compares the proximate composition (ash, moisture, protein, and lipid content), fatty acid profiles, mineral, and trace element content of three species of turbinid snails; Turbo militaris, Lunella undulata, and Lunella torquata from northern New South Wales, Australia. They were all found to have relatively high protein in their flesh (16.0% to 18.5% of the fresh weight). L. torquata had a significantly higher lipid content (8.5% w/w) than L. undulata (5.2% w/w), whereas T. militaris (5.6% w/w) was not significantly different to either. Analysis with gas chromatography showed there was no significant difference in monounsaturated fatty acid (MUFA) content, with an average of approximately 14% of the total fatty acids in all three species. However, saturated fatty acids (SFA) were significantly higher in T. militaris (41%), whereas polyunsaturated fatty acids (PUFA) were significantly higher in L. undulata (46%). The ratio of n−3/n−6 fatty acids ranged from 1.1 in T. militaris to 1.4 in L. torquata, which is good for human health and comparable to other high value gastropods. The results indicate that T. militaris, L. undulata, and L. torquata provide a good source of essential elements such as zinc, selenium, and iron. At the location studied, toxic metals and metalloids were below safe recommended standards for human consumption. Overall, this study confirms the suitability of turban snails as a nutritional food for human consumption.
