Which would you expect to resemble a sphingomyelin molecule more closely: a molecule of phosphatidyl choline containing two mole

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.
