Abstract
Leaf slices from spinach exhibited considerable variation in their incorporation of [(14)C]bicarbonate and [1-(14)C]acetate into fatty acids. Reductive ozonolysis studies indicated that all the (14)C-labeled fatty acids were synthesized de novo; no in vivo evidence was found for the previously proposed elongation of hexadecatrienoate to alpha-linolenate.
摘要
菠菜叶片在将 [(14)C]碳酸氢盐和 [1-(14)C]乙酸盐掺入脂肪酸方面表现出相当大的差异。还原臭氧化研究表明，所有标记的 (14)C 脂肪酸都是从头合成的；没有体内证据表明先前提出的将十六碳三烯酸延伸为α-亚麻酸。
