A cholesterol sample is prepared using acetyl CoA molecules in which both the methyl group and the carboxyl functional group of the acetyl are radiolabeled with ¹⁴C. In the cholesterol product, the ¹⁴C label would appear:

		a) only in the fused ring structure carbons of cholesterol.
		b) only in the hydrocarbon chain carbons of cholesterol.
		c) in all of the carbons of the cholesterol molecule.
		d) in one half of the carbons of cholesterol, as the carboxyl group of acetyl is release as CO2 in the synthesis of cholesterol.
