sphingolipid

 [sfing″go-lip´id]
a phospholipid containing sphingosine (e.g., ceramides, sphingomyelins, gangliosides, and cerebrosides), occurring in high concentrations in the brain and other nerve tissue.

sphin·go·lip·id

(sfing'gō-lip'id),
Any lipid containing a long-chain base like that of sphingosine (for example, ceramides, cerebrosides, gangliosides, sphingomyelins); a constituent of nerve tissue.

sphingolipid

(sfĭng′gə-lĭp′ĭd, -lī′pĭd)
n.
Any of a group of lipids, such as the ceramides, that yield sphingosine or its derivatives upon hydrolysis. They are major components of cell membranes and play a role in signaling and regulatory functions.

sphin·go·lip·id

(sfing'gō-lip'id)
Any lipid containing a long-chain base like that of sphingosine (e.g., ceramides, cerebrosides, gangliosides, sphingomyelins); a constituent of nerve tissue.

These metabolites belong to the categories of glycerophospholipids, sphingolipids, steroids and fatty acids, which were involved into glycerophospholipid metabolism, sphingolipid metabolism, fatty acid [beta]-oxidation pathway and bile acid biosynthesis.

A complex aspect of the "sphingolipid rheostat" is that ceramide can be converted to other sphingolipids with signalling properties.
In preliminary clinical studies, the technology demonstrated significantly better barrier function with substantial improvement in moisture retention when compared to commercially available sphingolipid compounds.
Discovery of the GlcCer-deficient cells and subsequent success in the molecular cloning of the GlcCer synthase gene triggered my research interest to re-focus metabolism and functions of common, basic, and simple sphingolipids instead of studying complex GSLs.
Their product line includes a broad range of sphingolipids, glycolipids, glycosphingolipids, fatty acids and esters, sterols, and vitamin E isomers (tocopherols and tocotrienols).
They looked specifically at acylcarnitines, phospholipids, lysophospholipids, and sphingolipids. They found that phospholipids were elevated in schizophrenia patients, compared with controls, and even more elevated in patients with bipolar disorder.
The toxicity can be explained by differences in sphingolipids, especially glycosylphosphatidyl inositol, present in the plasma membranes of both types of plants.
Within the refined profile, five clusters of metabolites emerged with prominent subpathways, including known mediators of lung disease such as sphingolipids (elevated in cases of WTC-LI), and branched-chain amino acids (reduced in cases of WTC-LI).
Deficient activity of N-acetylglucosamine-1-phosphotransferase leads to defective posttranslational modification of lysosomal enzymes, promoting the intracellular accumulation of both partly degraded glycosaminoglycans and sphingolipids. (1-3) The trafficking process that transports the lysosomal enzymes to the interior of lysosomes is impaired.
Sphingolipids are essential structural components of all cell membranes and highly bioactive compounds that play important roles in signal transduction and numerous other cellular processes such as cell proliferation, differentiation, and apoptosis.
