The chemical reactions and pathways involving tetraterpenoid compounds, terpenoids with eight isoprene units. A cyclic series of interconversions involving three xanthophylls, violoxanthin, antheraxanthin, and zeaxanthin. The xanthophyll cycle is involved in regulating energy dissipation in light harvesting complex II. The chemical reactions and pathways resulting in the breakdown of xanthophylls, oxygen-containing carotenoids. The chemical reactions and pathways involving xanthophylls, oxygen-containing carotenoids. The chemical reactions and pathways resulting in the formation of xanthophylls, oxygen-containing carotenoids. The chemical reactions and pathways involving carotenoids, tetraterpenoid compounds in which two units of 4 isoprenoid residues joined head-to-tail are themselves joined tail-to-tail.
