Galactosylsphingosine
Galactosylsphingosine (also known as psychosine), is an intermediate in the biosynthesis of cerebrosides. It is formed from the reaction of sphingosine with UDP-galactose and then reacts with fatty acid-coenzyme A to form the cerebroside. It is a galactoside metabolite of sphingosine and can function as a neurotoxin and a metabotoxin. A neurotoxin is a compound that disrupts or attacks neural cells and neural tissue. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of galactosylsphingosine are associated with globoid cell leukodystrophy (Krabbe disease), which is characterized by the dysfunction of galactosylceramidase. Galactosylsphingosine is a highly cytotoxic lipid capable of inducing cell death in a wide variety of cell types including oligodendrocytes. It is known to accumulate in the nervous system in the absence of galactosylceramidase. Galactosylsphingosine localizes to lipid rafts and perturbs membrane integrity. It also inhibits protein kinase C translocation to the plasma membrane (PMID: 24006512). Symptoms of Krabbe disease begin between the ages of 3 and 6 months with irritability, fevers, limb stiffness, seizures, feeding difficulties, vomiting, and slowing of mental and motor development. In the first stages of the disease, the symptoms are often mistaken with those of cerebral palsy. Other symptoms include muscle weakness, spasticity, deafness, optic atrophy, optic nerve enlargement, blindness, paralysis, and difficulty when swallowing. An intermediate in the biosynthesis of cerebrosides. It is formed by reaction of sphingosine with UDP-galactose and then itself reacts with fatty acid-Coenzyme A to form the cerebroside.

Glucosylsphingosine
Glucosylsphingosine is a cytotoxic compound. Accumulation of glucosylsphingosine in brain and other tisues occurs in patients with Gaucher disease, which is an inherited deficiency of lysosomal glucocerebrosidase. Glucocerebrosidase converts glucosylsphingosine to glucose and sphingosine. [HMDB] Glucosylsphingosine is a cytotoxic compound. Accumulation of glucosylsphingosine in brain and other tisues occurs in patients with Gaucher disease, which is an inherited deficiency of lysosomal glucocerebrosidase. Glucocerebrosidase converts glucosylsphingosine to glucose and sphingosine. Glucosylsphingosine (lyso-Gb1) is a deacylated form of glucosylceramide and is also degraded by the glucocerebrosidase. Glucosylsphingosine is a very promising, reliable and specific biomarker for monitoring Gaucher disease[1].
