c22 glucosylceramide (d18:1/22:0)

C22 Glucosylceramide (d18:1 22:0) is an endogenous glucosylceramide. Glucosylceramides are major constituents of skin lipid membranes where they play a role in maintaining the water permeability barrier. They are precursors in the synthesis of lactosylceramide , as well as oligoglycolipids and gangliosides. Phospholipase A2 (PLA2) type XIIA knockdown increases C22 glucosylceramide (d18:1 22:0) expression in rat brain. It is also increased in the brain, but not the liver or spinal cord, of mice fed a methionine-restricted diet. In human athletes, plasma levels of C22 glucosylceramide (d18:1 22:0) increase during exercise and return to basal levels during recovery. This product contains C22 glucosylceramide (d18:1 22:0) isolated from bovine buttermilk.

C22 Galactosylceramide is a sphingolipid that has been found in the central nervous system.1,2C22 Galactosylceramide levels are increased in the spinal cord, but not the brain or liver, of mice fed a methionine-restricted diet.1C22 Galactosylceramide has been found in postmortem hippocampus from patients with Alzheimer's disease.2[Matreya, LLC.]

C22 Sphingomyelin is a naturally occurring form of sphingomyelin . Plasma levels of C22 sphingomyelin positively correlate with hepatic steatosis severity in patients with chronic hepatitis C virus (HCV). C22 Sphingomyelin levels are decreased in T-47D mammary epithelial cells and increased in MDA-MB-231 breast cancer cells relative to C16 sphingomyelin .

C22 Ceramide (d18:1/22:0) (C22 Ceramide) 是一种从海绵Haliclona koremella 中分离出含有山嵛酸的长链神经酰胺，是一种内源性生物活性鞘脂。C22 Ceramide (d18:1/22:0) 可特异性抑制MCSR，降低离体大鼠肝线粒体和脂质体中 C16-神经酰胺通道的形成。
