FATTY ACID AND AMINO ACID COMPOSITIONS OF THE GASTROPODS, TONNA DOLIUM (LINNAEUS, 1758) AND PHALIUM GLAUCUM (LINNAEUS, 1758) FROM THE GULF OF MANNAR, SOUTHEAST COAST OF INDIA

Abstract
The amino acid and fatty acid contents of two gastropods viz. Tonna dolium and Phalium glaucum were determined from the Gulf of Mannar. The presences of 7 fatty acids were recorded in both species. The total fatty acid contents in T. dolium and P. glaucum were 7.63% and 6.34 % respectively. PUFA were the dominant fatty acid group, followed by SFA in both the species. For T. dolium, the most abundant fatty acids were, in decreasing order, C18:2ω-6, C18:0, C18:3ω-3, and C16:0 whereas in P. glaucum it were C18:2ω6, C18:3ω-3, C18:0 and C16:0. The total amino acid (TAA) contents of T. dolium and P. glaucum were 19.07% and 17.3% respectively. Among the TAA contents, the percentage of EAA and NEAA in T. dolium and P. glaucum were found to be 9.96%, 8.05% and 9.11%, 9.25% respectively. Methionine (1.40%), phenylalanine (1.31%), isoleucine (1.20%) and leucine (1.20%) in T. dolium and isoleucine (1.24%), methionine (1.12%) and phenylalanine (1.06%) in P. glaucum were determined as the most abundant EAA whereas alanine (1.40%) arginine (1.34%) and glycine (1.18%) in T. dolium and alanine (1.15%) arginine (1.15%) and glutamic acid (1.14%) in P. glaucum contributed as major non-essential amino acids.
