Interpretation: Among the terms glycerophospholipid, sphingophospholipid and sphingoglycolipid, the term that can be applied to the given characterization has to be predicted.
Concept introduction: The lipid that is composed of one fatty acid and one carbohydrate unit which are joined to a sphingosine molecule is known as sphingoglycolipid. The fatty acid of sphingoglycolipid is also joined to the sphingosine molecule with the help of amide linkage. The carbohydrate unit joined to a sphingosine molecule with the help of glycosidic linkage.
The lipids based on glycerol are called glycerophospholipids. They are basically made up of two fatty acids, a phosphate group which is esterified to glycerol and an alcohol group which is esterified to the phosphate group.
The lipids that are composed of a fatty acid and a phosphate group which is joined with a sphingosine molecule and an alcoholic group is known as sphingophospholipids.
