Cholesterol synthesis is a multi-step process starting from acetyl-CoA and resulting in a 37-carbon molecule.

“how do we make cholesterol very complexly it's a multi-stage process 20 to 30 individual steps where one molecule is changing into another into another and at the end of the day cholesterol is made and it starts very small it's basically acetyl co a acetyl co a it's two carbon chain molecule that keeps growing in length because cholesterol is 37 carbons in it”
