Lipids, Vinyl Alcohols, and Fatty Acids From Soft Tissues of the Bivalve Mollusk Mactra chinensis

The compositions of lipids, vinyl alcohols, and fatty acids from total lipids of the soft tissues of the bivalve mollusk Mactra chinensis were analyzed. Bound lipids were found to be dominant in all parts and made up > 83.3% of the lipid mass predominantly in adductor. The total contents of dimethylacetals in various mollusk parts were 3.3-11.9% of the total FAs predominantly in motor muscle and viscera. The lipids contained 39 FAs of various structures with different quantitative contents and localizations of which 6 were saturated; 14, unsaturated, and 19, polyunsaturated. Adductor and muscle contained 37 FAs; viscera, 38 FAs.
