| GO:0006713 | 0 | The chemical reactions and pathways resulting in the breakdown of glucocorticoids, hormonal C21 corticosteroids synthesized from cholesterol. |
| GO:0008208 | 0 | The chemical reactions and pathways resulting in the breakdown of C21-steroid hormones, steroid compounds containing 21 carbons which function as hormones. |
| GO:0016127 | 0 | The chemical reactions and pathways resulting in the breakdown of sterols, steroids with one or more hydroxyl groups and a hydrocarbon side-chain in the molecule. |
| GO:0016130 | 0 | The chemical reactions and pathways resulting in the breakdown of phytosteroids, steroids of higher plants differing from animal steroids C1 or C2 residues at C24 and/or a double bond at C22. |
| GO:0030573 | 0 | The chemical reactions and pathways resulting in the breakdown of bile acids, any of a group of steroid carboxylic acids occurring in bile. |
| GO:0042369 | 0 | The chemical reactions and pathways resulting in the breakdown of vitamin D, any of a group of related, fat-soluble compounds that are derived from delta-5,7 steroids and play a central role in calcium metabolism.
