Which Component of Cholesterol Would Classify It as a Lipid

Question

Which component of cholesterol would classify it as a lipid?
A) carbohydrates
B) phosphates
C) glycerol
D) hydrocarbons

Accepted Answer

Cholesterol is classified as a lipid because it is made up of hydrocarbons, specifically a four-ring hydrocarbon structure. Lipids are defined by their hydrophobic characteristic and a high proportion of nonpolar C-H bonds, which are present in cholesterol. The other options, carbohydrates, phosphates, and glycerol, are all hydrophilic components commonly found in other types of biomolecules such as nucleic acids and lipids.
