Steroids belong to the class of biochemicals called lipids.

Here's why:

* Lipids are a broad category of organic molecules that are characterized by their insolubility in water and their solubility in organic solvents. They include fats, oils, waxes, phospholipids, and steroids.

* Steroids are a specific type of lipid that have a characteristic four-ring structure. They are essential for various biological processes, including hormone production, cell signaling, and membrane structure.

So, while steroids are a distinct group, they fall under the larger category of lipids.
