N-Glycolylneuraminic acid

(2S,4S,5R,6R)-2,4-dihydroxy-5-(2-hydroxyacetamido)-6-[(1R,2R)-1,2,3-trihydroxypropyl]oxane-2-carboxylic acid

C11H19NO10 (325.1009)


N-Glycolylneuraminic acid (Neu5Gc) is a widely expressed sialic acid found in most mammalian cells. Although humans are genetically deficient in producing Neu5Gc, small amounts are present in human cells and biofluids. Humans cannot synthesize Neu5Gc because the human gene CMAH is irreversibly mutated, though it is found in apes. This loss of the CMAH gene was estimated to have occurred two to three million years ago, just before the emergence of the genus Homo. A dietary origin of Neu5Gc was suggested by human volunteer studies. These trace amounts of Neu5Gc were determined to come from the consumption of animals in the human diet (i.e. red meats such as lamb, pork, and beef). Neu5Gc can also be found in dairy products, but to a lesser extent. Neu5Gc is not found in poultry and is found in only trace amounts in fish (Wikipedia). Isolated from beef serum KEIO_ID G062

   

Glucosamine

(3R,4R,5S,6R)-3-Amino-6-(hydroxymethyl)oxane-2,4,5-triol

C6H13NO5 (179.0794)


Glucosamine (C6H13NO5) is an amino sugar and a prominent precursor in the biochemical synthesis of glycosylated proteins and lipids. Glucosamine is part of the structure of two polysaccharides, chitosan and chitin. Glucosamine is one of the most abundant monosaccharides. Produced commercially by the hydrolysis of shellfish exoskeletons or, less commonly, by fermentation of a grain such as corn or wheat, glucosamine has many names depending on country. Although a common dietary supplement, there is little evidence that it is effective for relief of arthritis or pain, and is not an approved prescription drug. In the United States, glucosamine is not approved by the Food and Drug Administration for medical use in humans. Since glucosamine is classified as a dietary supplement, evidence of safety and efficacy is not required as long as it is not advertised as a treatment for a medical condition. Nevertheless, glucosamine is a popular alternative medicine used by consumers for the treatment of osteoarthritis. Glucosamine is also extensively used in veterinary medicine as an unregulated but widely accepted supplement. Treatment with oral glucosamine is commonly used for the treatment of osteoarthritis. Since glucosamine is a precursor for glycosaminoglycans, and glycosaminoglycans are a major component of joint cartilage, supplemental glucosamine may help to rebuild cartilage and treat arthritis. However, there is little evidence that any clinical effect of glucosamine works this way. Its use as a therapy for osteoarthritis appears safe but there is conflicting evidence as to its effectiveness. Glucosamine is naturally present in the shells of shellfish, animal bones, bone marrow, and fungi. D-Glucosamine is made naturally in the form of glucosamine-6-phosphate, and is the biochemical precursor of all nitrogen-containing sugars. Specifically in humans, glucosamine-6-phosphate is synthesized from fructose 6-phosphate and glutamine by glutamine—fructose-6-phosphate transaminase as the first step of the hexosamine biosynthesis pathway. The end-product of this pathway is uridine diphosphate N-acetylglucosamine (UDP-GlcNAc), which is then used for making glycosaminoglycans, proteoglycans, and glycolipids. As the formation of glucosamine-6-phosphate is the first step for the synthesis of these products, glucosamine may be important in regulating their production; however, the way that the hexosamine biosynthesis pathway is actually regulated, and whether this could be involved in contributing to human disease remains unclear. Present in mucopolysaccharides and in polysaccharides found in bacteria, fungi, higher plants, invertebrates, vertebrates, antibiotics and UDP complexes.

UDP-α-D-N-Acetylglucosamine disodium

(2R,3R,4R,5S,6R)-3-(Acetylamino)-4,5-dihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl [(2R,3S,4R,5R)-5-(2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-3,4-dihydroxytetrahydrofuran-2-yl]methyl dihydrogen diphosphoric acid (non-preferred name)

C17H27N3O17P2 (607.0816)


Uridine diphosphate-N-acetylglucosamine (uridine 5-diphosphate-GlcNAc, or UDP-Glc-NAc) is an acetylated aminosugar nucleotide. UDP-GlcNAc is the donor substrate for modification of nucleocytoplasmic proteins at serine and threonine residues with N-acetylglucosamine (O-GlcNAc). Nutrient sensing in mammals is done through the hexosamine biosynthetic pathway (HSP), which produces uridine 5-diphospho-N-acetylglucosamine (UDP-Glc-NAc) as its end product. Mammals respond to nutrient excess by activating O-GlcNAcylation (addition of O-linked N-acetylglucosamine). O-GlcNAc addition (and removal) is key to histone remodeling, transcription, proliferation, apoptosis, and proteasomal degradation. This nutrient-responsive signaling pathway also modulates important cellular pathways, including the insulin signaling cascade in. Alterations in O-GlcNAc metabolism are associated with various human diseases including diabetes mellitus and neurodegeneration. (PMID: 16317114) Due to the chemical makeup of UDP-GlcNAc, it is well positioned to serve as a glucose sensor in that it is a high-energy compound that requires and/or responds to glucose, amino acid, fatty acid and nucleotide metabolism for synthesis. Elevated levels of O-GlcNAc have an effect on insulin-stimulated glucose uptake. (PMID: 12678487).

β-D-Fructose 6-phosphate

[(2R,3R,4S)-2,3,4,6-tetrahydroxy-5-oxohexyl] dihydrogen phosphate

C6H13O9P (260.0297)


Fructose 6-phosphate (F6P) belongs to the class of organic compounds known as hexose phosphates. These are carbohydrate derivatives containing a hexose substituted by one or more phosphate groups. F6P is a derivative of fructose, which has been phosphorylated at the 6-hydroxy group. Fructose 6-phosphate is a fundamental metabolite and exists in all living species, ranging from bacteria to plants to humans. The great majority of glucose is converted to fructose 6-phosphate as part of the glycolytic metabolic pathway (glycolysis). Specifically, F6P is produce is produced by the isomerisation of glucose 6-phosphate via the enzyme phosphoglucose isomerase. F6P is in turn further phosphorylated to fructose-1,6-bisphosphate by the enzyme phosphofructokinase-1. Glycolysis is the metabolic pathway that converts glucose into pyruvic acid. The free energy released in this process is used to form ATP and reduced nicotinamide adenine dinucleotide (NADH). In addition to its key involvement in glycolysis, fructose 6-phosphate can also be biosynthesized from glucosamine 6-phosphate via the enzyme glucosamine-6-phosphate isomerase 1. In addition, fructose 6-phosphate and L-glutamine can be converted into glucosamine 6-phosphate and L-glutamic acid through the action of the enzyme glutamine--fructose-6-phosphate aminotransferase. An important intermediate in the Carbohydrates pathway. The interconversion of glucose-6-phosphate and fructose-6-phosphate, the second step of the Embden-Meyerhof glycolytic pathway, is catalyzed by the enzyme phosphoglucose isomerase (PGI). In gluconeogenesis, fructose-6-phosphate is the immediate precursor of glucose-6-phosphate (wikipedia) [HMDB] Acquisition and generation of the data is financially supported in part by CREST/JST.
