Answer:
A phosphatidyl choline molecule with one molecule of palmitate and one molecule of oleate as its fatty acid side chains
Explanation:
Sphingomyelin is a sphingolipid conisting of following components :
1) Phosphocholine head group
2) Sphingosine ( amino alcohol containing long unsaturated hydrocarbon chain )
3) Fatty acid.
A bend is introduced due to the presence of oleate in one of the side chains that will closely resemble the shape of sphingomyelin, because the latter also has a double bond and hence a bend.
Hence a phosphatidyl choline molecule with one molecule of palmitate and one molecule of oleate as its fatty acid side chains will resemble a sphingomyelin molecule more closely.
