Verified step by step guidance

Steroid hormones are a class of lipids that are derived from a specific precursor molecule. To solve this, we need to identify the biochemical origin of steroid hormones.

Recall that steroid hormones, such as cortisol, testosterone, and estrogen, share a common structural feature: a four-ringed sterane backbone. This structure is synthesized from a precursor lipid molecule.

Cholesterol is the precursor molecule for all steroid hormones. It undergoes enzymatic modifications in the mitochondria and endoplasmic reticulum of steroidogenic tissues to produce various steroid hormones.

Fatty acids, phospholipids, and triglycerides are other types of lipids, but they do not serve as precursors for steroid hormones. Instead, they have roles in energy storage, membrane structure, and signaling.

Thus, the correct answer is 'Cholesterol,' as it is the lipid from which all steroid hormones are derived.
