Organic chemical analysis and biosynthetic study of fatty acids and the metabolites produced by mites

亚油酸的生物合成一般仅限于能够在油酸的ω-6位插入双键的动物，包括特定类别的昆虫。通过同位素标记化合物的掺入实验，证明了亚油酸的从头合成。为了证明亚油酸直接转化为不饱和烃，用核磁共振波谱测定了这些化合物的标记位置和掺杂率。因此，这些数据支持亚油酸通过释放CO_2或CO而转化为不饱和烃的机理。

The biosynthesis of linoleic acid is generally restricted to animals capable of inserting a double bond into theω-6 position of oleic acid, and includes specific class of insects. The de novo biosynthesis of linoleic acid was demonstrated by incorporation experiments of isotope-labeled compounds in astigmatid mites. To demonstrate the direct conversion of linoleic acid into unsaturated hydrocarbon, labeled positions and incorporation rates in those compounds were determined by NMR spectra. As a result, the data support a mechanism in which linoleic acid is converted to unsaturated hydrocarbon by release of CO_2 or CO.
