Stéaróideach

Is éard is stéaróideach ann ná lipid theirpéinóideach arb é a príomhthréith a chroí steréin agus grúpaí feidhmiúla breise. Tá a croí comhdhéanta de struchtúr carbóin de cheithre fáinní comhleáite: trí fáinní cioglaiheacsán agus fáinne amháin cioglaipeintáine. Athraíonn na stéaróidigh de réir na grúpaí feidhmiúla a ghabhann leis na fáinní seo agus staid ocsaídithe na bhfáinní.

Tarlaíonn raon leathan de chomhdhúile ceimiceacha go
nádúrtha i bplandaí, in ainmhithe, agus i bhfungais.

However, retinoic acid is not a steroid because it does not have the defining ring structure. See: Steroids and Related Hydrophobic Molecules.
