Glyoxylic acid

2-oxoacetic acid

C2H2O3 (74.0004)


Glyoxylic acid or oxoacetic acid is an organic compound that is both an aldehyde and a carboxylic acid. Glyoxylic acid is a liquid with a melting point of -93°C and a boiling point of 111°C. It is an intermediate of the glyoxylate cycle, which enables certain organisms to convert fatty acids into carbohydrates. The conjugate base of glyoxylic acid is known as glyoxylate (PMID: 16396466). In humans, glyoxylate is produced via two pathways: (1) through the oxidation of glycolate in peroxisomes and (2) through the catabolism of hydroxyproline in mitochondria. In the peroxisomes, glyoxylate is converted into glycine by glyoxylate aminotransferase (AGT1) or into oxalate by glycolate oxidase. In the mitochondria, glyoxylate is converted into glycine by mitochondrial glyoxylate aminotransferase AGT2 or into glycolate by glycolate reductase. A small amount of glyoxylate is converted into oxalate by cytoplasmic lactate dehydrogenase. Glyoxylic acid is found to be associated with primary hyperoxaluria I, which is an inborn error of metabolism. Under certain circumstances, glyoxylate can be a nephrotoxin and a metabotoxin. A nephrotoxin is a compound that causes damage to the kidney and kidney tissues. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. High levels of glyoxylate are involved in the development of hyperoxaluria, a key cause of nephrolithiasis (commonly known as kidney stones). Glyoxylate is both a substrate and inductor of sulfate anion transporter-1 (SAT-1), a gene responsible for oxalate transportation, allowing it to increase SAT-1 mRNA expression, and as a result oxalate efflux from the cell. The increased oxalate release allows the buildup of calcium oxalate in the urine, and thus the eventual formation of kidney stones. As an aldehyde, glyoxylate is also highly reactive and will modify proteins to form advanced glycation products (AGEs). Glyoxylic acid, also known as alpha-ketoacetic acid or glyoxylate, is a member of the class of compounds known as carboxylic acids. Carboxylic acids are compounds containing a carboxylic acid group with the formula -C(=O)OH. Glyoxylic acid is soluble (in water) and a moderately acidic compound (based on its pKa). Glyoxylic acid can be found in a number of food items such as european chestnut, cowpea, wheat, and common thyme, which makes glyoxylic acid a potential biomarker for the consumption of these food products. Glyoxylic acid can be found primarily in blood, cerebrospinal fluid (CSF), feces, and urine, as well as throughout all human tissues. Glyoxylic acid exists in all living species, ranging from bacteria to humans. In humans, glyoxylic acid is involved in a couple of metabolic pathways, which include alanine metabolism and glycine and serine metabolism. Glyoxylic acid is also involved in several metabolic disorders, some of which include lactic acidemia, pyruvate carboxylase deficiency, 3-phosphoglycerate dehydrogenase deficiency, and hyperglycinemia, non-ketotic. Moreover, glyoxylic acid is found to be associated with transurethral resection of the prostate and primary hyperoxaluria I. Glyoxylic acid or oxoacetic acid is an organic compound. Together with acetic acid, glycolic acid, and oxalic acid, glyoxylic acid is one of the C2 carboxylic acids. It is a colourless solid that occurs naturally and is useful industrially .

N-Nitrosodimethylamine

N-Methyl-N-nitrosomethanamine, 9ci

C2H6N2O (74.048)


N-Nitrosodimethylamine is found in pepper (Capsicum annuum). N-Nitrosodimethylamine is a food contaminant especially in cured meat products. N-Nitrosodimethylamine (NDMA), also known as dimethylnitrosamine (DMN), is a semi-volatile organic chemical that is highly toxic and is a suspected human carcinogen. The US Environmental Protection Agency has determined that the maximum admissible concentration of NDMA in drinking water is 7 ng L 1. The EPA has not yet set a regulatory maximum contaminant level (MCL) for drinking water. At high doses, it is a "potent hepatotoxin that can cause fibrosis of the liver" in rats. The induction of liver tumors in rats after chronic exposure to low doses is well-documented. Its toxic effects on humans are inferred from animal experiments but not well-established experimentally. NDMA is an industrial by-product or waste product of several industrial processes. It first came to attention as a groundwater contaminant in California in 1998 and 1999 at several sites that produced rocket fuel. Manufacturing of unsymmetrical dimethylhydrazine (UDMH), which is a component of rocket fuel that requires NDMA for its synthesis, proved to be the culprit in these cases. Of more general concern, water treatment via chlorination or chloramination of organic nitrogen-containing wastewater can lead to the production of NDMA at potentially harmful levels. Further, NDMA can form or be leached during treatment of water by anion exchange resins. Finally, NDMA is found at low levels in numerous items of human consumption including cured meat, fish, beer, and tobacco smoke, it is, however, unlikely to bioaccumulate CONFIDENCE standard compound; EAWAG_UCHEM_ID 3447 Food contaminant especies in cured meat products

   

Methyl acetate

Ethyl ester OF monoacetic acid

C3H6O2 (74.0368)

Propionic acid

propionate;Methylacetic acid

C3H6O2 (74.0368)


Propionic acid (PA) is an organic acid. It exists a clear liquid with a pungent and unpleasant smell somewhat resembling body odor. Propionic acid (PA) is widely used as an antifungal agent in food. It is present naturally at low levels in dairy products and occurs ubiquitously, together with other short-chain fatty acids (SCFA), in the gastro-intestinal tract of humans and other mammals as an end-product of the microbial digestion of carbohydrates. The metabolism of propionic acid begins with its conversion to propionyl coenzyme A, the usual first step in the metabolism of carboxylic acids. Since propionic acid has three carbons, propionyl-CoA cannot directly enter either beta oxidation or the citric acid cycles. In most vertebrates, propionyl-CoA is carboxylated to D-methylmalonyl-CoA, which is isomerised to L-methylmalonyl-CoA. Propionic acid has significant physiological activity in animals. Propionic acid is irritant but produces no acute systemic effects and has no demonstrable genotoxic potential (PMID 1628870). The human skin is host of several species of bacteria known as Propionibacteria, which are named after their ability to produce propionic acid. The most notable one is the Cutibacterium acnes (formerly known as Propionibacterium acnes), which lives mainly in the sebaceous glands of the skin and is one of the principal causes of acne. Propionic aciduria is one of the most frequent organic acidurias, a disease that comprise many various disorders. The outcome of patients born with Propionic aciduria is poor intellectual development patterns, with 60\\\% having an IQ less than 75 and requiring special education. Successful liver and/or renal transplantations, in a few patients, have resulted in better quality of life but have not necessarily prevented neurological and various visceral complications. These results emphasize the need for permanent metabolic follow-up whatever the therapeutic strategy (PMID 15868474). Decreased early mortality, less severe symptoms at diagnosis, and more favorable short-term neurodevelopmental outcome were recorded in patients identified through expanded newborn screening. (PMID 16763906)↵ When propionic acid is infused directly into rodents brains, it produces hyperactivity, dystonia, social impairment, perseveration and brain changes (e.g., innate neuroinflammation, glutathione depletion) that may be used as a means to model autism in rats. Propionic acid is a metabolite of Bacteroides, Clostridium, Dialister, Megasphaera, Phascolarctobacterium, Propionibacterium, Propionigenum, Salmonella, Selenomonas and Veillonella (https://www.mdpi.com/2311-5637/3/2/21). Propionic acid, also known as propionate or ethanecarboxylic acid, is a member of the class of compounds known as carboxylic acids. Carboxylic acids are compounds containing a carboxylic acid group with the formula -C(=O)OH. Thus, propionic acid is considered to be a fatty acid lipid molecule. Propionic acid is soluble (in water) and a weakly acidic compound (based on its pKa). Propionic acid can be found in a number of food items such as celery stalks, burbot, sapodilla, and dock, which makes propionic acid a potential biomarker for the consumption of these food products. Propionic acid can be found primarily in most biofluids, including feces, saliva, blood, and urine, as well as throughout most human tissues. Propionic acid exists in all living species, ranging from bacteria to humans. In humans, propionic acid is involved in a couple of metabolic pathways, which include propanoate metabolism and vitamin K metabolism. Propionic acid is also involved in few metabolic disorders, which include malonic aciduria, malonyl-coa decarboxylase deficiency, and methylmalonic aciduria due to cobalamin-related disorders. Moreover, propionic acid is found to be associated with propionic acidemia. Propionic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound.

3-Hydroxypropanal is a broad-spectrum antimicrobial substance termed reuterin produced by Lactobacillus reuteri. L. reuteri resides in the gastrointestinal tract of healthy humans and animals, and is believed to. function as a symbiont in the enteric ecosystem. Synthesis of such an antimicrobial substance by an enteric resident raises a number of interesting questions and possibilities as to the role these residents may play in the health of the host. (PMID 3245697). In vivo, glycerol is converted in one enzymatic step into 3-Hydroxypropanal. The 3-Hydroxypropanal -producing Lactobacillus reuteri is used as a probiotic in the health care of humans and animals. 3-Hydroxypropanal forms, together with Hydroxypropanal-hydrate and Hydroxypropanal-dimer, a dynamic, multi-component system (Hydroxypropanal system) used in food preservation, as a precursor for many modern chemicals such as acrolein, acrylic acid, and 1,3-propanediol (1,3-PDO), and for polymer production. 3-Hydroxypropanal can be obtained both through traditional chemistry and bacterial fermentation. To date, 3-HPA has been produced from petrochemical resources as an intermediate in 1,3-PDO production. The biotechnological production of 3-Hydroxypropanal from renewable resources is desirable both for use of 3-Hydroxypropanal in foods and for the production of bulk chemicals. The main challenge will be the efficient production and recovery of pure 3-Hydroxypropanal.

These are carboxylic acid derivatives in which the carbon atom from the carbonyl group is attached to an alkyl or an aryl moiety through an oxygen atom (forming an ester group). Ethyl formate is an alcohol, bitter, and cognac tasting compound. Ethyl formate has been detected, but not quantified, in several different foods, such as citrus, pineapples, apples, fruits, and pomes. This could make ethyl formate a potential biomarker for the consumption of these foods. It occurs naturally in the body of ants and in the stingers of bees. Ethyl formate has the characteristic smell of rum and is also partially responsible for the flavor of raspberries. The U.S. National Institute for Occupational Safety and Health (NIOSH) also considers a time-weighted average of 100 ppm over an eight-hour period as the recommended exposure limit. Ethyl formate is an ester formed when ethanol (an alcohol) reacts with formic acid (a carboxylic acid). According to the U.S Occupational Safety and Health Administration (OSHA), ethyl formate can irritate eyes, skin, mucous membranes, and the respiratory system of humans and other animals; it is also a central nervous system depressant. Ethyl formate has been identified in dust clouds in an area of the Milky Way galaxy called Sagittarius B2 and it is among 50 molecular species identified using the 30 metre IRAM radiotelescope. In industry, it is used as a solvent for cellulose nitrate, cellulose acetate, oils, and greases. Found in various foods, e.g. cooked apple, orange juice, pineapple, other fruits, raw cabbage, coffee, black tea, wheat bread, white clover, sorghum. It is used as a flavouring agent.

1,3-diaminopropane, also known as trimethylenediamine or 1,3-propanediamine, is a member of the class of compounds known as monoalkylamines. Monoalkylamines are organic compounds containing an primary aliphatic amine group. 1,3-diaminopropane is soluble (in water) and a very strong basic compound (based on its pKa). 1,3-diaminopropane can be found in a number of food items such as apricot, redcurrant, french plantain, and agar, which makes 1,3-diaminopropane a potential biomarker for the consumption of these food products. 1,3-diaminopropane can be found primarily in blood, feces, and urine. 1,3-diaminopropane exists in all eukaryotes, ranging from yeast to humans. In humans, 1,3-diaminopropane is involved in the beta-alanine metabolism. 1,3-diaminopropane is also involved in few metabolic disorders, which include carnosinuria, carnosinemia, gaba-transaminase deficiency, and ureidopropionase deficiency. Moreover, 1,3-diaminopropane is found to be associated with perillyl alcohol administration for cancer treatment and leukemia.
