Sphingomyelin (d18:1/24:1, d18:2/24:0)

Sphingomyelin (d18:1/24:1(15Z)) or SM(d18:1/24:1(15Z)) is a type of sphingolipid found in animal cell membranes, especially in the membranous myelin sheath which surrounds some nerve cell axons. It usually consists of phosphorylcholine and ceramide. SM(d18:1/24:1(15Z)) consists of a sphingosine backbone and a nervonic acid chain. In humans, sphingomyelin is the only membrane phospholipid not derived from glycerol. Like all sphingolipids, SM has a ceramide core (sphingosine bonded to a fatty acid via an amide linkage). In addition, it contains one polar head group, which is either phosphocholine or phosphoethanolamine. The plasma membrane of cells is highly enriched in sphingomyelin and is considered largely to be found in the exoplasmic leaflet of the cell membrane. However, there is some evidence that there may also be a sphingomyelin pool in the inner leaflet of the membrane. Moreover, neutral sphingomyelinase-2, an enzyme that breaks down sphingomyelin into ceramide, has been found to localize exclusively to the inner leaflet further suggesting that there may be sphingomyelin present there. Sphingomyelin can accumulate in a rare hereditary disease called Niemann-Pick Disease, types A and B. Niemann-Pick disease is a genetically-inherited disease caused by a deficiency in the enzyme sphingomyelinase, which causes the accumulation of sphingomyelin in spleen, liver, lungs, bone marrow, and the brain, causing irreversible neurological damage. SMs play a role in signal transduction. Sphingomyelins are synthesized by the transfer of phosphorylcholine from phosphatidylcholine to a ceramide in a reaction catalyzed by sphingomyelin synthase.

C51H88O7 (812.653)

Diglycerides (DGs) are also known as diacylglycerols or diacylglycerides, meaning that they are glycerides consisting of two fatty acid chains covalently bonded to a glycerol molecule through ester linkages. DG(13D5/13D5/0:0), in particular, consists of one chain of 13-(3,4-dimethyl-5-pentylfuran-2-yl)tridecanoic acid at the C-1 position and one chain of 13-(3,4-dimethyl-5-pentylfuran-2-yl)tridecanoic acid at the C-2 position. Mono- and diacylglycerols are common food additives used to blend together certain ingredients, such as oil and water, which would not otherwise blend well. Diacylglycerols are often found in bakery products, beverages, ice cream, chewing gum, shortening, whipped toppings, margarine, and confections.

Sphingomyelin (d18:2(4E,14Z)/24:0) or SM(d18:2(4E,14Z)/24:0) is a type of sphingolipid found in animal cell membranes, especially in the membranous myelin sheath which surrounds some nerve cell axons.
