The Content of Fat and Polyenoic Acids in the Major Food Sources of the Arctic Diet. Localization of Double Bonds in Fatty Acids by Means of Mass Spectrometry of Fatty Acid Pyrrolidides
Abstract The fatty acid pattern of muscle and fat tissue of the arctic seal, birds and mammals are presented and compared with the fatty acid pattern of the corresponding tissues of domestic animals normally used as meat sources in western countries. The triglyceride content of muscle samples were a...
