What is a Sphingolipid?

Sphingolipids are amphiphilic lipids containing a sphingosine skeleton. One end is connected to a long-chain fatty acid and the other end is a polar alcohol. Sphingomyelin, including sphingomyelin, cerebroside, and ganglioside, is generally found in plant and animal membranes, especially in tissues of the central nervous system. Also known as sphingomyelin, sphingosine phospholipid, or neurophospholipid. A molecule composed of sphingosine, fatty acids, and phosphorylcholine. It is a typical representative of sphingomyelins, and is extremely abundant in the tissues of higher animals. The hydrolysis of phospholipids is catalyzed by the neurophospholipase in the lysosome. The hydrolysate is ceramide and choline phosphate, which can continue to be metabolized. Congenital defects of phospholipase cause sphingomyelin to accumulate in the tissue; it can cause liver and spleen Swelling, severe cases affect the central nervous system, and even life-threatening

Sphingolipid fraction

Sphingomyelin is an important component of the structure of biofilms. With the in-depth study of sphingolipids in animals and yeast, it has been discovered that sphingolipids and their metabolites are important active molecules that participate in regulating cell growth, differentiation, and aging. And programmed cell death, etc. Many important signal transduction processes. Studies on sphingolipids in plants have only begun in recent years, and the function of plant sphingolipids is not very clear. Recent studies have found that sphingolipids and their metabolites are found in plants. It also plays an important role as a signal molecule. ^[
