It has been demonstrated that conjugated linoleic acid isomers with the first double bond in position 9 (cis) or 10 (trans), added exogenously, can be desaturated in position 6 by the cyanobacterium
Spirulina platensis
. The metabolites, 6-cis, 9-cis, 11-trans-octadecatrienoic and 6-cis,10-trans,12-cis-octadecatrienoic acids, which have not previously been characterized, were isolated by a combination of chromatographic techniques and the structures were confirmed by gas chromatography-mass spectrometry in the form of picolinyl ester and dimethyloxazoline derivatives.
研究表明,外源添加的共轭亚油酸异构体的第一个双键位于第 9 位(顺式)或第 10 位(反式),可以通过蓝藻的作用使第 6 位脱饱和
蓝藻
.这些代谢物,即 6-顺式、9-顺式、11-反式-十八碳三烯酸和 6-顺式、10-反式、12-顺式-十八碳三烯酸,以前从未被表征过,它们通过色谱技术的组合被分离出来,并以吡啶酯和二甲基噁唑啉衍生物的形式通过气相色谱-质谱法确认了其结构。
