초록

The proximate, fatty acid and dimethyl acetal (DMA) composition, and mineral and total amino acid content of limpets Cellana spp. were studied. Limpets contained 17.6% protein, 1.82% lipids, and 1.28% ash. The most prominent fatty acids in limpets were 20:4n-6, 20:5n-3, 18:1n-9, 16:0, 18:0, and 22:2 nonmethylene-interrupted diene (7,13). Limpets contained significant amounts of 18:0DMA (7.79%) and 20:0DMA (2.45%) derived from plasmalogen. They also contained large amounts of calcium (192.4 mg/100 g) and iron (9.4 mg/100 g), which are components of limpet teeth. The most prominent total amino acids were glutamic acid, arginine, aspartic acid, leucine, lysine, and glycine. These results suggest that limpets are a good source of n-3 and n-6 fatty acids, plasmalogen, calcium iron, and arginine.
