The fact that palmitoyl-l-carnitine is oxidized by avocado mitochondria at a rate comparable with that of succinate oxidation suggests that there are at least two systems for beta-oxidation in higher plants. The carnitine-associated system is located in a mitochondrial fraction, whereas the glyoxylate-cycle-associated system is located in the glyoxysomes.
事实上,鳄梨线粒体氧化棕榈酰肉碱的速度与琥珀酸氧化的速度相当,这表明高等植物中至少存在两种β-氧化系统。肉碱相关系统位于线粒体部分,而乙醛酸循环相关系统位于乙醛酸体中。
