For this example question it says, which one of the following statements about sphingomyelins is incorrect? Here, the fatty acid at carbon 2 is attached through an amide linkage. That there is true, so this can't be an answer. The Baquemolecule in sphingomyelins is Sphingosine. That is also true. It's not glycerol like we've seen in other molecules, it's sphingosine. Sphingomyelins are essential for the structural integrity of the myelin sheath. This is an important fact when it comes to our sphingomyelin. So, this is also true. So, odd one out is d. Let's see why that why that is. A sphingomyelin has only one tail because it contains one fatty acid. So, here we have a fatty acid chain at carbon number 2, but it has more than one tail. It has also a hydrocarbon tail at carbon number 3, but we have also the presence of that trans double bond. So here, this statement is incorrect. So here, the answer would be option d. This is the only incorrect statement out of the 4 given to us.
