C22 Galactosylceramide (d18:1/22:0)

C22 Galactosylceramide is a sphingolipid that has been found in the central nervous system. C22 Galactosylceramide levels are increased in the spinal cord, but not the brain or liver, of mice fed a methionine-restricted diet. C22 Galactosylceramide has been found in postmortem hippocampus from patients with Alzheimer's disease. As this product is derived from a natural source, there may be variations in the sphingoid backbone. [Matreya, LLC.
