Alpha-ketobutyrate
3-methyl pyruvic acid, also known as alpha-ketobutyric acid or 2-oxobutyric acid, belongs to short-chain keto acids and derivatives class of compounds. Those are keto acids with an alkyl chain the contains less than 6 carbon atoms. Thus, 3-methyl pyruvic acid is considered to be a fatty acid lipid molecule. 3-methyl pyruvic acid is soluble (in water) and a weakly acidic compound (based on its pKa). 3-methyl pyruvic acid can be found in a number of food items such as pepper (c. baccatum), triticale, european plum, and black walnut, which makes 3-methyl pyruvic acid a potential biomarker for the consumption of these food products. 3-methyl pyruvic acid can be found primarily in blood, cerebrospinal fluid (CSF), saliva, and urine. 3-methyl pyruvic acid exists in all living species, ranging from bacteria to humans. In humans, 3-methyl pyruvic acid is involved in several metabolic pathways, some of which include methionine metabolism, homocysteine degradation, threonine and 2-oxobutanoate degradation, and propanoate metabolism. 3-methyl pyruvic acid is also involved in several metabolic disorders, some of which include dimethylglycine dehydrogenase deficiency, methylenetetrahydrofolate reductase deficiency (MTHFRD), s-adenosylhomocysteine (SAH) hydrolase deficiency, and hyperglycinemia, non-ketotic. 2-Ketobutyric acid, also known as alpha-ketobutyrate or 2-oxobutyrate, belongs to the class of organic compounds known as short-chain keto acids and derivatives. These are keto acids with an alkyl chain the contains less than 6 carbon atoms. 2-Ketobutyric acid is a substance that is involved in the metabolism of many amino acids (glycine, methionine, valine, leucine, serine, threonine, isoleucine) as well as propanoate metabolism and C-5 branched dibasic acid metabolism. It is also one of the degradation products of threonine. It can be converted into propionyl-CoA (and subsequently methylmalonyl CoA, which can be converted into succinyl CoA, a citric acid cycle intermediate), and thus enter the citric acid cycle. More specifically, 2-ketobutyric acid is a product of the lysis of cystathionine. 2-Oxobutanoic acid is a product in the enzymatic cleavage of cystathionine.
Succinic acid semialdehyde
Succinic acid semialdehyde (or succinate semialdehyde) is an intermediate in the catabolism of gamma-aminobutyrate or GABA (PMID:16435183). It is formed from GABA by the action of GABA transaminase, which leads to the production of succinate semialdehyde and alanine. The resulting succinate semialdehyde is further oxidized by succinate semialdehyde dehydrogenase to become succinic acid, which also yields NADPH. Under certain situations, high levels of succinate semialdehyde can function as a neurotoxin and a metabotoxin. A neurotoxin is a compound that causes damage to the brain and nerve tissues. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Elevated serum levels of succinate semialdehyde are found in succinic semialdehyde dehydrogenase (SSADH) deficiency (gamma-hydroxybutyric aciduria), a rare neurometabolic disorder of gamma-aminobutyric acid (GABA) degradation. Symptoms include motor delay, hypotonia, speech delay, autistic features, seizures, and ataxia. Patients also exhibit behavioural problems such as attention deficit, hyperactivity, anxiety, or aggression (PMID:18622364). Succinate semialdehyde is considered a reactive carbonyl and may lead to increased oxidative stress. This stress is believed to contribute to the formation of free radicals in the brain tissue of animal models induced with SSADH deficiency, which further leads to secondary cell damage and death. Additionally, oxidative stress may be responsible for the loss of striatal dopamine, which may contribute to the neuropathology of SSADH deficiency. Succinic acid semialdehyde is an intermediate in the catabolism of gamma-aminobutyrate (PMID 16435183). Succinate semialdehyde dehydrogenase is an enzyme that catalyses the reaction of succinate semialdehyde and NAD+ to form succinate and NADH. Succinic semialdehyde dehydrogenase (SSADH) deficiency (gamma-hydroxybutyric aciduria) is a rare neurometabolic disorder of gamma-aminobutyric acid degradation.

Succinic acid semialdehyde is found in many foods, some of which are yellow zucchini, japanese chestnut, banana, and pineappple sage.
Valerate
Valeric acid, or pentanoic acid, is a straight chain alkyl carboxylic acid with the chemical formula CH3(CH2)3COOH. Like other low molecular weight carboxylic acids, it has a very unpleasant odor. Valeric acid is commonly found in human feces, with an average concentration of 2.4 umol/g feces (range of 0.6-3.8 umol/g) (PMID:6740214). Valeric acid is produced by the gut microbiota, typically Clostridia species and other gut bacterial species such as Megasphaera massiliensis MRx0029 (PMID:30052654) via the condensation of ethanol with propionic acid (PMID:18116989). Valeric acid is largely considered as a gut microbial metabolite. Recently, valeric acid has been found to exert strong gut protective effects. Studies involving mice that received high doses of radiation showed that valeric acid replenishment (via oral gavage) elevated the survival rate of irradiated mice, protected hematogenic organs (such as the thymus and spleen), improved gastrointestinal (GI) tract function and enhanced intestinal epithelial integrity (PMID:31931652 ). Valeric acid was also found to restore the enteric bacteria taxonomic proportions and reprogram the small intestinal protein profile to normal levels. Valeric acid, like butyric acid, also appears to be a potent histone deacetylase (HDAC) inhibitor. High levels of HDAC proteins have been implicated in a variety of disease pathologies, from cancer and colitis to cardiovascular disease and neurodegeneration (PMID:30052654). Valeric acid is also found in certain plants, specifically in the perennial flowering plant valerian (Valeriana officinalis), from which it gets its name. Industrially valeric acid is primarily used is in the synthesis of its esters. Volatile esters of valeric acid tend to have pleasant odors and are used in perfumes and cosmetics. Ethyl valerate and pentyl valerate are used as food additives because of their fruity flavours. Hydrolysis of these valerate-containing food additives in the gut can also lead to the appearance of valerate in blood, urine and stool samples. Minor constituent of biological systems e.g. yeast fat, some plant oilsand is also present in blue cheeses, wines, apple, banana, morello cherry, cooked shrimp, scallop, roasted peanut, roasted filberts and other foodstuffs.

Acetoacetate
Acetoacetic acid (AcAc) is a weak organic acid that can be produced in the human liver under certain conditions of poor metabolism leading to excessive fatty acid breakdown (diabetes mellitus leading to diabetic ketoacidosis). It is then partially converted into acetone by decarboxylation and excreted either in urine or through respiration. Persistent mild hyperketonemia is a common finding in newborns. Ketone bodies serve as an indispensable source of energy for extrahepatic tissues, especially the brain and lung of developing rats. Another important function of ketone bodies is to provide acetoacetyl-CoA and acetyl-CoA for synthesis of cholesterol, fatty acids, and complex lipids. During the early postnatal period, acetoacetate and beta-hydroxybutyrate are preferred over glucose as substrates for synthesis of phospholipids and sphingolipids in accord with requirements for brain growth and myelination. Thus, during the first two weeks of postnatal development, when the accumulation of cholesterol and phospholipids accelerates, the proportion of ketone bodies incorporated into these lipids increases. On the other hand, an increased proportion of ketone bodies are utilized for cerebroside synthesis during the period of active myelination. In the lung, AcAc serves better than glucose as a precursor for the synthesis of lung phospholipids. The synthesized lipids, particularly dipalmityl phosphatidylcholine, are incorporated into surfactant, and thus have a potential role in supplying adequate surfactant lipids to maintain lung function during the early days of life (PMID: 3884391). The acid is also present in the metabolism of those undergoing starvation or prolonged physical exertion as part of gluconeogenesis. When ketone bodies are measured by way of urine concentration, acetoacetic acid, along with beta-hydroxybutyric acid or acetone, is what is detected.

Thus, during the first 2 wk of postnatal development, when the accumulation of cholesterol and phospholipids accelerates, the proportion of ketone bodies incorporated into these lipids increases. On the other hand, an increased proportion of ketone bodies are utilized for cerebroside synthesis during the period of active myelination. In the lung, AcAc serves better than glucose as a precursor for the synthesis of lung phospholipids. The synthesized lipids, particularly dipalmityl phosphatidylcholine, are incorporated into surfactant, and thus have a potential role in supplying adequate surfactant lipids to maintain lung function during the early days of life. (PMID 3884391) The acid is also present in the metabolism of those undergoing starvation or prolonged physical exertion as part of gluconeogenesis. When ketone bodies are measured by way of urine concentration, acetoacetic acid, along with beta-hydroxybutyric acid or acetone, is what is detected. [HMDB]
