Heptanoic acid
Heptanoic acid, or C7:0 also known as enanthic acid or heptylic acid, belongs to the class of organic compounds known as medium-chain fatty acids. Medium-chain fatty acids (MCFA) are fatty acids with aliphatic tails of 6 to 12 carbons, which can form medium-chain triglycerides Heptanoic acid is an oily liquid with an unpleasant, rancid odor. It contributes to the odor of some rancid oils. It is slightly soluble in water, but very soluble in ethanol and ether. Its name derives from the Latin oenanthe which is in turn derived from the Ancient Greek oinos "wine" and anthos "blossom." Heptanoic acid is used in the preparation of esters, such as ethyl enanthate, which are used in fragrances and as artificial flavors. The triglyceride ester of heptanoic acid is the triheptanoin, which is used in certain medical conditions as a nutritional supplement. Present in essential oils, e.g. violet leaf oil, palm oiland is also present in apple, feijoa fruit, strawberry jam, clove bud, ginger, black tea, morello cherry, grapes, rice bran and other foodstuffs. Flavouring ingredient. It is used as one of the components in washing solns. used to assist lye peeling of fruit and vegetables

3-methyl-2-oxovalerate
3-Methyl-2-oxovaleric acid (CAS: 1460-34-0) is an abnormal metabolite that arises from the incomplete breakdown of branched-chain amino acids. 3-Methyl-2-oxovaleric acid is a neurotoxin, an acidogen, and a metabotoxin. A neurotoxin causes damage to nerve cells and nerve tissues. 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. Chronically high levels of 3-methyl-2-oxovaleric acid are associated with maple syrup urine disease. MSUD is a metabolic disorder caused by a deficiency of the branched-chain alpha-keto acid dehydrogenase complex (BCKDC), leading to a buildup of the branched-chain amino acids (leucine, isoleucine, and valine) and their toxic by-products (ketoacids) in the blood and urine. The symptoms of MSUD often show in infancy and lead to severe brain damage if untreated. MSUD may also present later depending on the severity of the disease. If left untreated in older individuals, during times of metabolic crisis, symptoms of the condition include uncharacteristically inappropriate, extreme, or erratic behaviour and moods, hallucinations, anorexia, weight loss, anemia, diarrhea, vomiting, dehydration, lethargy, oscillating hypertonia and hypotonia, ataxia, seizures, hypoglycemia, ketoacidosis, opisthotonus, pancreatitis, rapid neurological decline, and coma. In maple syrup urine disease, the brain concentration of branched-chain ketoacids can increase 10- to 20-fold. This leads to a depletion of glutamate and a consequent reduction in the concentration of brain glutamine, aspartate, alanine, and other amino acids. The result is a compromise of energy metabolism because of a failure of the malate-aspartate shuttle and a diminished rate of protein synthesis (PMID: 15930465). 3-Methyl-2-oxovaleric acid is a keto-acid, which is a subclass of organic acids. 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). These can progress to heart, liver, and kidney abnormalities, seizures, coma, and possibly death. These are also the characteristic symptoms of untreated MSUD. Many affected children with organic acidemias experience intellectual disability or delayed development. (s)-3-methyl-2-oxopentanoate, also known as (3s)-2-oxo-3-methyl-N-valeric acid or (S)-omv, 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, (s)-3-methyl-2-oxopentanoate is considered to be a fatty acid lipid molecule (s)-3-methyl-2-oxopentanoate is slightly soluble (in water) and a weakly acidic compound (based on its pKa). (s)-3-methyl-2-oxopentanoate can be found in a number of food items such as bean, prickly pear, wild leek, and nutmeg, which makes (s)-3-methyl-2-oxopentanoate a potential biomarker for the consumption of these food products (s)-3-methyl-2-oxopentanoate may be a unique S.cerevisiae (yeast) metabolite.
Ketoleucine
Ketoleucine is an abnormal metabolite that arises from the incomplete breakdown of branched-chain amino acids. Ketoleucine is both a neurotoxin and a metabotoxin. A neurotoxin causes damage to nerve cells and nerve tissues. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of ketoleucine are associated with maple syrup urine disease (MSUD). MSUD is a metabolic disorder caused by a deficiency of the branched-chain alpha-keto acid dehydrogenase complex (BCKDC), leading to a buildup of the branched-chain amino acids (leucine, isoleucine, and valine) and their toxic by-products (ketoacids) in the blood and urine. The symptoms of MSUD often show in infancy and lead to severe brain damage if untreated. MSUD may also present later depending on the severity of the disease. If left untreated in older individuals, during times of metabolic crisis, symptoms of the condition include uncharacteristically inappropriate, extreme, or erratic behaviour and moods, hallucinations, anorexia, weight loss, anemia, diarrhea, vomiting, dehydration, lethargy, oscillating hypertonia and hypotonia, ataxia, seizures, hypoglycemia, ketoacidosis, opisthotonus, pancreatitis, rapid neurological decline, and coma. In maple syrup urine disease, the brain concentration of branched-chain ketoacids can increase 10- to 20-fold. This leads to a depletion of glutamate and a consequent reduction in the concentration of brain glutamine, aspartate, alanine, and other amino acids. The result is a compromise of energy metabolism because of a failure of the malate-aspartate shuttle and a diminished rate of protein synthesis (PMID: 15930465). Ketoleucine, also known as alpha-ketoisocaproic acid or 2-oxoisocaproate, 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. Ketoleucine is slightly soluble (in water) and a weakly acidic compound (based on its pKa). Ketoleucine can be found in a number of food items such as arctic blackberry, sesame, sea-buckthornberry, and soft-necked garlic, which makes ketoleucine a potential biomarker for the consumption of these food products. Ketoleucine can be found primarily in most biofluids, including saliva, blood, cerebrospinal fluid (CSF), and urine, as well as in human muscle, neuron and prostate tissues. Ketoleucine exists in all living species, ranging from bacteria to humans. In humans, ketoleucine is involved in the valine, leucine and isoleucine degradation. Ketoleucine is also involved in several metabolic disorders, some of which include methylmalonate semialdehyde dehydrogenase deficiency, propionic acidemia, 3-methylglutaconic aciduria type IV, and 3-methylglutaconic aciduria type I. Ketoleucine is a non-carcinogenic (not listed by IARC) potentially toxic compound. Ketoleucine is a metabolite that accumulates in Maple Syrup Urine Disease (MSUD) and shown to compromise brain energy metabolism by blocking the respiratory chain (T3DB). 4-Methyl-2-oxopentanoic acid (α-Ketoisocaproic acid), an abnormal metabolite, is both a neurotoxin and a metabotoxin.

In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Outside of the human body, Isopentyl acetate is found, on average, in the highest concentration within a few different foods, such as red wines, white wines, and beers. Isopentyl acetate has also been detected, but not quantified in, several different foods, such as blackberries (Rubus), figs (Ficus carica), red teas, bananas (Musa acuminata), and black elderberries (Sambucus nigra). This could make isopentyl acetate a potential biomarker for the consumption of these foods. Isopentyl acetate occurs naturally in the banana plant and it is also produced synthetically. Based on a literature review a significant number of articles have been published on Isopentyl acetate. Pure isopentyl acetate, or mixtures of isopentyl acetate, amyl acetate, and other flavors may be referred to as banana oil. Because of its intense, pleasant odor and its low toxicity, isopentyl acetate is used to test the effectiveness of respirators or gas masks.
