生物体内的长链不饱和脂肪酸、不饱和脂肪醇(醛)和长链烯烃等大多具有各种不同的生物活性,具有生长、性吸引、警报和通讯等功能。其活性常决定于化合物中双键的数目和位置以及混合物中各组分的比例。近年来,用化学衍生和GC/MS手段确定脂肪酸和烯烃双键位置的工作已大量开 In vivo, most of the long chain unsaturated fatty acids, unsaturated fatty alcohols (aldehydes) and long-chain olefins have a variety of different biological activity, growth, sexual attraction, alarm and communication functions. Its activity is often determined by the number and position of double bonds in the compound and the proportions of the individual components in the mixture. In recent years, the use of chemical derivatization and GC / MS to determine the position of fatty acid and olefin double bonds has been largely open
