검증된 단계별 안내1
Identify the structure of a glycerol backbone, which is a three-carbon molecule with hydroxyl groups attached to each carbon.
Understand that a triacylglycerol is formed when three fatty acid molecules are esterified to the hydroxyl groups of the glycerol backbone.
Recognize that a sphingolipid typically contains a sphingosine backbone, not glycerol, and usually has one fatty acid attached.
Note that a phospholipid consists of a glycerol backbone, two fatty acids, and a phosphate group, not three fatty acids.
Cholesterol is a sterol and does not have a glycerol backbone or fatty acids attached, distinguishing it from triacylglycerols.
