Are steroids unsaturated or saturated lipids?

Steroids are classified as a type of lipid, but they do not fall neatly into the categories of saturated or unsaturated fats. Instead, steroids are characterized by a structure of four fused carbon rings and can have various functional groups attached. While they are not defined by saturation levels like fatty acids, some steroid molecules can have double bonds within their rings, which might give them properties akin to unsaturated compounds in certain contexts.
