The chemical reactions and pathways involving brassinosteroids, any of a group of steroid derivatives that occur at very low concentrations in plant tissues and may have hormone-like effects.

The chemical reactions and pathways resulting in the breakdown of phytosteroids, steroids that differ from animal steroids in having substitutions at C24 and/or a double bond at C22. Phytosteroids are so named because they occur in higher plants; some, notably ergosterol, are also found in fungi.
