摘要

采用放射性标记基质,研究了马铃薯块茎片对花生四烯酸(AA)和其他选定脂肪酸的代谢。观察到的主要代谢物是甘油。大量未代谢的酸也被回收。在培养条件下,没有检测到由无细胞系统产生的预期的AA代谢物,如氢过氧化物或环戊烯酮。脂肪酸的激发子活性与其代谢速率不相关。

The metabolic fate of arachidonic acid applied to potato tuber slices

The metabolism of arachidonic acid (AA) and other selected fatty acids by potato (Solanum tuberosum) tuber slices was followed with the use of radioactive labeled substrates. The predominant metabolites observed were glyceries. Significant quantities of the unmetabolized acids were also recovered. None of the expected AA metabolites such as hydroperoxides or cyclopentenones that are produced by cell-free systems could be detected under the incubation conditions. The elicitor activity of the fatty acids could not be correlated with their rate of metabolism.
