Which of the following molecules contain sphingosine? Select all that apply.
Revelant knowledge
Sphingosine: A long-chain, unsaturated amino alcohol C 18H 37O 2N that is found primarily in cell membranes. It’s the main component of sphingolipids.
Molecules: A group of atoms that are joined together, which is the smallest elemental component that makes up a chemical compound which is able to participate in chemical reactions.
The knowledge of sphingomyelins or sphingosines is the basis for the solution to the problem.
Sphingomyelins, sphingolipids, are found in the cell membranes and myelin sheaths of nerve cells. It is made up of the sphingosine molecular, a fatty acid, and the phosphorylcholine. These combine together to create the sphingomyelin.
Structure of molecule B doesn’t contain sphingosine
Similar to phosphatidylcholine, it does not contain sphingosine.
Sphingosine generally consists of an 18-carbon chain with an amino alcohol group attached.
Sphingosine is composed of an ammonium group that attacks on the carbonyl carbon in the fatty acids to form an amide derivative.
This is the reaction of sphingosine and the fatty acid:
The active phosphate group attack of the terminal oxygen atom in the sphingosine derivative is the phosphoryl choline. This attack on the phosphate group creates the phosphoester bonds which form sphingomyelins.
These are the reactions of phosphoryl Choline and its sphingosine derivative:
