Positional isomers of decenoic, dodecenoic, and tetradecenoic acids of human adipose tissue have been separated by gas-liquid chromatography and their amounts determined by oxidative cleavage. The following acids have been shown to be present: 7-decenoic, 8-decenoic, 9-decenoic, 7-, 8-, and 9-dodecenoic, and 7-, 8-, 9-, and 11-tetradecenoic acids. Among all isomers of the even-numbered acids from C(10) to C(18) the cis-9-isomer predominates. With increasing chain length, however, the content of 9-isomer decreases and the number of isomers increases. No 3- or 5-enoic acids could be detected. The origin and biosynthesis of all isomers are discussed.
人脂肪组织中癸烯酸、十二碳烯酸和十四碳烯酸的位置异构体已通过气液色谱法分离，并通过氧化裂解测定了它们的含量。已证明存在以下几种酸：7-癸烯酸、8-癸烯酸、9-癸烯酸、7-、8-和9-十二碳烯酸，以及7-、8-、9-和11-十四碳烯酸。在从C(10)到C(18)的偶数酸的所有异构体中，顺式-9-异构体占主导。然而，随着链长的增加，9-异构体的含量降低，异构体的数量增加。未检测到3-或5-烯酸。讨论了所有异构体的来源和生物合成。
