Abstract
A major pathway for fatty acid oxidation in several plants is a-oxidation. In animals a-oxidation is an alternative pathway to β-oxidation and the activity is low. The localization and mechanism of a-oxidation is not fully understood either in plants or in animals. An a-oxidation system in plants has been suggested [1] (Fig. 1), the first step involving decarboxylation of a long-chain fatty acid (Cn) to a long-chain aldehyde (Cn-1). This aldehyde is rapidly oxidized by a NAD+ dependent long-chain aldehyde dehydrogenase to the corresponding free fatty acid (Cn-1) which can then be recycled into the sequence for further a-oxidation. Earlier we observed high a-oxidation activity in cucumber, the activity being located in particles sedimenting with a s-value of 10 500 ± 850 S [2].
