The metabolism of phytanic acid involves alpha-oxidation in the peroxisome, which converts phytanic acid to pristanic acid. Peroxisomes involved in the catabolism of very long chain fatty acids and phytanic acid. Peroxisomal malfunctioning can lead to over-accumulation of very long chain fatty acids and phytanic acid, among other things. HP:0010571 An abnormal elevation of phytanic acid.
