Saccharopine

(2S)-2-{[(5S)-5-amino-5-carboxypentyl]amino}pentanedioic acid

C11H20N2O6 (276.1321)

Saccharopine is an intermediate in the degradation of lysine, formed by the condensation of lysine and alpha-ketoglutarate. The saccharopine pathway is the main route for lysine degradation in mammals, and its first two reactions are catalyzed by enzymatic activities known as lysine-oxoglutarate reductase (LOR) and saccharopine dehydrogenase (SDH), which reside on a single bifunctional polypeptide (LOR/SDH) (EC 1.5.1.8). The reactions involved with saccharopine dehydrogenases have very strict substrate specificity for L-lysine, 2-oxoglutarate, and NADPH. LOR/SDH has been detected in a number of mammalian tissues, mainly in the liver and kidney, contributing not only to the general nitrogen balance in the organism but also to the controlled conversion of lysine into ketone bodies. A tetrameric form has also been observed in human liver and placenta. LOR activity has also been detected in brain mitochondria during embryonic development, and this opens up the question of whether or not lysine degradation has any functional significance during brain development. As a result, there is now a new focus on the nutritional requirements for lysine in gestation and infancy. Finally, LOR and/or SDH deficiencies seem to be involved in a human autosomal genetic disorder known as familial hyperlysinemia, which is characterized by serious defects in the functioning of the nervous system and characterized by a deficiency in lysine-ketoglutarate reductase, saccharopine dehydrogenase, and saccharopine oxidoreductase activities. Saccharopinuria (high amounts of saccharopine in the urine) and saccharopinemia (an excess of saccharopine in the blood) are conditions present in some inherited disorders of lysine degradation (PMID: 463877, 10567240, 10772957, 4809305). If present in sufficiently high levels, saccharopine can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Saccharopine is an organic acid. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). Many affected children with organic acidemias experience intellectual disability or delayed development. Amino acid from Saccharomyces cerevisiae and Neurospora crassaand is also found in mushrooms and seeds

5-Amino-6-ribitylamino uracil

5-amino-6-{[(2S,3S,4R)-2,3,4,5-tetrahydroxypentyl]amino}-1,2,3,4-tetrahydropyrimidine-2,4-dione

C9H16N4O6 (276.107)

5-Amino-6-ribitylamino uracil is an intermediate in riboflavin metabolism. It is converted from 5-amino-6-(5-phosphoribitylamino)uracil via dephosphorylation by the enzyme phosphohistidine phosphatase 1 (EC 3.1.3.-). It is considered to be the second product of the riboflavin synthase reaction (PMID: 14245407). Humans do not have all the enzymes needed to synthesize or metabolize riboflavin. However, gut microflora do have the necessary enzymatic machinery to produce and metabolize this vitamin. Riboflavin (or vitamin B2) is an easily absorbed micronutrient with a key role in maintaining health in humans and animals. It is the central component of the cofactors FAD and FMN, and is therefore required by all flavoproteins. Riboflavin is yellow or yellow-orange in colour and in addition to being used as a food colouring it is also used to fortify some foods including baby foods, breakfast cereals, pastas, sauces, processed cheese, fruit drinks, vitamin-enriched milk products, some energy drinks, and vitamin supplements. 5-amino-6-(d-ribitylamino)uracil, also known as 5-amino-6-ribitylamino-2,4-(1h,3h)pyrimidinedione or 5-arpd, is a member of the class of compounds known as pentoses. Pentoses are monosaccharides in which the carbohydrate moiety contains five carbon atoms. 5-amino-6-(d-ribitylamino)uracil is soluble (in water) and a very weakly acidic compound (based on its pKa). 5-amino-6-(d-ribitylamino)uracil can be found in a number of food items such as radish (variety), chinese cabbage, common beet, and spinach, which makes 5-amino-6-(d-ribitylamino)uracil a potential biomarker for the consumption of these food products. 5-amino-6-(d-ribitylamino)uracil exists in E.coli (prokaryote) and yeast (eukaryote).

N-lactoyl-Tryptophan

(2S)-2-{[(2S)-1,2-dihydroxypropylidene]amino}-3-(1H-indol-3-yl)propanoate

C14H16N2O4 (276.111)

N-lactoyl-Tryptophan is lactoyl derivative of tryptophan. N-lactoyl-amino acids are ubiquitous pseudodipeptides of lactic acid and amino acids that are rapidly formed by reverse proteolysis. A protease, cytosolic nonspecific dipeptidase 2 (CNDP2), catalyzes their formation. The plasma levels of these metabolites strongly correlate with plasma levels of lactate and amino acid.
