What are the types of water-labile bonds present in both Sphingomyelin and phosphatidylcholine?
Homework Answers
Sphingomyelin is also called ceramide 1-phosphocholine,since it consists of a phosphorylcholine moiety attached to position 1 of the sphingoid base component. It is zwitter ionic. sphingomyelin has a hydroxyl on position 3 and an amide bond at position 2 of the sphingoid base, both groups are capable of hydrogen bonding. It also consists of trans double bond which appears to assist intermolecular interactions in membranes. Whereas in phosphatidylcholine, the two ester carbonyl groups can act only as hydrogen acceptors. The degree of unsaturation of the alkyl moieties in sphigomyelin and phosphatidylcholine is very different, and results in the dissimilarity of packing properties in membranes.
