(part b) Both fats and oils are glycosides in sequence. They are classed as "nonpolar fatty acid-containing lipids." Cattle use fats as protracted energy storage. They're molecules that aren't polar.

Found in cell membranes.

(part a) Cholesterol is a hydrocarbon that would be an essential constituent of the membrane of animal cells.

Thus the correct options are (a) Cholesterol

Found in cell membranes.

It also serves as a catalyst for the manufacture of growth factors. Glycolipids include carbohydrates that've been linked to bilayers in living cells.

Thus the correct options are (c) Carbohydrates.
