Question

Lipids (select the BEST CORRECT statement)

		Dihydrotestosterone is a chemical derivative of cholesterol.
		The more saturated a fatty acid is, the more likely it is to be solid at room temperature.
		Both glycerol and monoglycerides can freely diffuse across the apical membrane of intestinal epithelial cells.
		In triglyceride molecules, the fatty acids are linked to glycerol by covalent bonds.
		All of the above are correct
		Only (a), (b), and (c) are correct

Answer 1

All the above are correct

The principal androgens in humans are testosterone and dihydrotestosterone. The precursors of which are cholesterol

Saturated fatty acid means containing single bonds. Hence these are more closely packed together giving it a solid appearance at room temperature.

Glycerol and monoglycerides are monomers or simple molecules and hence can diffuse through the intestinal membrane.

In triglycerides, three fatty acids are linked to by glycerol through covalent bonds.
