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].
(5Z,8Z,10E,14Z,17Z)-12-Hydroxyicosa-5,8,10,14,17-pentaenoylcarnitine
C27H43NO5 (461.31410680000005)
(5Z,8Z,10E,14Z,17Z)-12-hydroxyicosa-5,8,10,14,17-pentaenoylcarnitine is an acylcarnitine. More specifically, it is an (5Z,8Z,10E,14Z,17Z)-12-hydroxyicosa-5,8,10,14,17-pentaenoic acid ester of carnitine. Acylcarnitines were first discovered more than 70 year ago (PMID: 13825279). It is believed that there are more than 1000 types of acylcarnitines in the human body. The general role of acylcarnitines is to transport acyl-groups (organic acids and fatty acids) from the cytoplasm into the mitochondria so that they can be broken down to produce energy. This process is known as beta-oxidation. According to a recent review [Dambrova et al. 2021, Physiological Reviews], acylcarnitines (ACs) can be classified into 9 different categories depending on the type and size of their acyl-group: 1) short-chain ACs; 2) medium-chain ACs; 3) long-chain ACs; 4) very long-chain ACs; 5) hydroxy ACs; 6) branched chain ACs; 7) unsaturated ACs; 8) dicarboxylic ACs and 9) miscellaneous ACs. Short-chain ACs have acyl-groups with two to five carbons (C2-C5), medium-chain ACs have acyl-groups with six to thirteen carbons (C6-C13), long-chain ACs have acyl-groups with fourteen to twenty once carbons (C14-C21) and very long-chain ACs have acyl groups with more than 22 carbons. (5Z,8Z,10E,14Z,17Z)-12-hydroxyicosa-5,8,10,14,17-pentaenoylcarnitine is therefore classified as a long chain AC. As a long-chain acylcarnitine (5Z,8Z,10E,14Z,17Z)-12-hydroxyicosa-5,8,10,14,17-pentaenoylcarnitine is generally formed through esterification with long-chain fatty acids obtained from the diet. The main function of most long-chain acylcarnitines is to ensure long chain fatty acid transport into the mitochondria (PMID: 22804748). Altered levels of long-chain acylcarnitines can serve as useful markers for inherited disorders of long-chain fatty acid metabolism. Carnitine palmitoyltransferase I (CPT I, EC:2.3.1.21) is involved in the synthesis of long-chain acylcarnitines (more than C12) on the mitochondrial outer membrane. Elevated serum/plasma levels of long-chain acylcarnitines are not only markers for incomplete FA oxidation but also are indicators of altered carbohydrate and lipid metabolism. High serum concentrations of long-chain acylcarnitines in the postprandial or fed state are markers of insulin resistance and arise from insulins inability to inhibit CPT-1-dependent fatty acid metabolism in muscles and the heart (PMID: 19073774). Increased intracellular content of long-chain acylcarnitines is thought to serve as a feedback inhibition mechanism of insulin action (PMID: 23258903). In healthy subjects, increased concentrations of insulin effectively inhibits long-chain acylcarnitine production. Several studies have also found increased levels of circulating long-chain acylcarnitines in chronic heart failure patients (PMID: 26796394). The study of acylcarnitines is an active area of research and it is likely that many novel acylcarnitines will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered. An excellent review of the current state of knowledge for acylcarnitines is available at [Dambrova et al. 2021, Physiological Reviews].
