Concept explainers
(a)
Interpretation: The classification of the given component of a sphingoglycolipid whether being a part of its “head” or part of its “tail” has to be predicted.
Concept introduction: The lipid that is composed of one fatty acid and one carbohydrate unit which is 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.
