This study was carried out on the composition of fatty acids in selected tissues (gonad, mantle, hepatopancreas, foot and whole body) of Eobania vermiculata (Muller, 1774) with the purpose of associating nutritional value of the edible parts. A total of 22 fatty acids were detected and quantified by gas chromatography-flame ionization detection (GC-FID). In all tissues, C16:0, C18:0, C18:1ω9, C18:2ω6, C20:2ω6 and C20:4ω6 have been discovered as dominant components. C18:1ω9 was found in high levels in whole body (21.20%) and in hepatopancreas (18.18%). C18:2ω6 was low in the gonad (15.83%) compared to the other four tissues. C20:4ω6, precursor of eicosanoids, was detected at the highest level in the gonad (17.98%) and at the lowest level in the hepatopancreas (9.75%). C20:2ω6 was found at high proportions in mantle and gonad tissues, 14.52% and 14.49%, respectively. The ∑PUFA levels were higher than the ∑SFA and ∑MUFA levels in all tissues. ∑PUFA were between 55.73% and 61.57%. The overall ratio of ω6/ω3 was defined as follows: gonad 13.23, mantle 7.66, hepatopancreas 2.40, foot 7.01, and whole body 4.87. Edible snails have significant amounts of essential fatty acids, minerals, vitamins A, K, E and B12 and low cholesterol. They are a good source of PUFAs, which help heart disease and boost the immune system. Consequently, the study found that five tissues from E. vermiculata are good sources of PUFA, the essential fatty acids C18:2ω6, C20:2ω6 and C20:4ω6.
