Great comprehensive article on sphingomyelin. At this stage, if you are preparing for the MCAT, it may not be wise to try to learn the deeper biochemistry of sphingomyelin, so you might treat the material after the first few paragraphs as optional reading comprehension.

Biological Membranes

In the biosynthesis of phosphoglycerides, an important component of cell membranes, two of the hydroxyl groups of glycerol are esterified to a fatty acid while the third is esterified to a phosphoric acid moeity. The phosphoric acid moeity has been further modified by esterifying to an additional alcohol, usually choline.
