3,4-Dihydroxyphenylglycol
3,4-Dihydroxyphenylglycol, also known as DHPG or DOPEG, belongs to the class of organic compounds known as catechols. Catechols are compounds containing a 1,2-benzenediol moiety. 3,4-Dihydroxyphenylglycol is an extremely weak basic (essentially neutral) compound. 3,4-Dihydroxyphenylglycol exists in all living organisms, ranging from bacteria to plants to humans. It is a potent antioxidant (PMID: 30007612). In mammals, 3,4-Dihydroxyphenylglycol is the primary metabolite of norepinephrine and is generated through the action of the enzyme monoamine oxidase (MAO). DHPG is then further metabolized by the enzyme Catechol-O-methyltransferase (COMT) to 3-methoxy-4-hydroxyphenylglycol (MHPG). Within humans, 3,4-dihydroxyphenylglycol participates in a number of enzymatic reactions. In particular, 3,4-dihydroxyphenylglycol can be biosynthesized from 3,4-dihydroxymandelaldehyde; which is mediated by the enzyme alcohol dehydrogenase 1A. In addition, 3,4-dihydroxyphenylglycol and guaiacol can be converted into vanylglycol and pyrocatechol through its interaction with the enzyme catechol O-methyltransferase. Outside of the human body, 3,4-dihydroxyphenylglycol is found, on average, in the highest concentration in olives. High levels of DHPG (up to 368 mg/kg of dry weight) have been found in the pulp of natural black olives. This could make 3,4-dihydroxyphenylglycol a potential biomarker for the consumption of olives and olive oil. 3,4-Dihydroxyphenylglycol has been linked to Menkes disease (PMID: 19234788). DHPG level are lower in Menkes patients (3.57 ± 0.40 nM) than healthy infants 8.91 ± 0.77 nM). Menkes disease (also called “kinky hair disease”) is an X-linked recessive neurodevelopmental disorder caused by defects in a gene that encodes a copper-transporting ATPase (ATP7A). Affected infants typically appear healthy at birth and show normal neurodevelopment for 2-3 months. Subsequently there is loss of milestones (e.g., smiling, visual tracking, head control) and death in late infancy or childhood (PMID: 19234788). 3,4-Dihydroxyphenylglycol (DOPEG) is a normal norepinephrine metabolite present in CSF, plasma and urine in humans (PMID 6875564). In healthy individuals there is a tendency for free DOPEG to increase and for conjugated DOPEG to decrease with age; plasmatic DOPEG levels are significantly lower in depressed patients as compared to healthy controls (PMID 6671452). DL-1-(3,4-Dihydroxyphenyl)-1,2-ethanediol is found in olive. 4-(1,2-Dihydroxyethyl)benzene-1,2-diol, a normal norepinephrine metabolite, is found to be associated with Menkes syndrome.

1,4-Dihydronicotinamide adenine dinucleotide
Nicotinamide adenine dinucleotide (NAD) is a coenzyme central to metabolism. Found in all living cells, NAD is called a dinucleotide because it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine nucleobase and the other nicotinamide. NAD exists in two forms: an oxidized and reduced form, abbreviated as NAD+ and NADH (H for hydrogen) respectively. NADH is the reduced form of NAD+, and NAD+ is the oxidized form of NADH. NAD (or nicotinamide adenine dinucleotide) is used extensively in glycolysis and the citric acid cycle of cellular respiration. The reducing potential stored in NADH can be either converted into ATP through the electron transport chain or used for anabolic metabolism. ATP "energy" is necessary for an organism to live. Green plants obtain ATP through photosynthesis, while other organisms obtain it via cellular respiration. NAD is a coenzyme composed of ribosylnicotinamide 5-diphosphate coupled to adenosine 5-phosphate by a pyrophosphate linkage. It is found widely in nature and is involved in numerous enzymatic reactions in which it serves as an electron carrier by being alternately oxidized (NAD+) and reduced (NADH). NADP is formed through the addition of a phosphate group to the 2 position of the adenosyl nucleotide through an ester linkage.

NADH is found in many foods, some of which are dill, ohelo berry, fox grape, and black-eyed pea. Acquisition and generation of the data is financially supported in part by CREST/JST.

3,4-Dihydroxymandelaldehyde
3,4-Dihydroxymandelaldehyde is the monoamine oxidase (MAO) aldehyde metabolite of both norepinephrine and epinephrine. 3,4- dihydroxymandelaldehyde generates a free radical and activates mitochondrial permeability transition, a mechanism implicated in neuron death. There is an increasing body of evidence suggesting that these compounds are neurotoxic, and it has been recently hypothesized that neurodegenerative disorders may be associated with increased levels of this biogenic aldehyde. It is possible to speculate that reduced detoxification of 3,4- dihydroxymandelaldehyde from impaired or deficient aldehyde dehydrogenase function may be a contributing factor in the suggested neurotoxicity of these compounds. Aldehyde dehydrogenases are a group of NAD(P)+ -dependent enzymes that catalyze the oxidation of aldehydes, such as those derived from catecholamines, to their corresponding carboxylic acids. To date, 19 aldehyde dehydrogenase genes have been identified in the human genome. Mutations in these genes and subsequent inborn errors in aldehyde metabolism are the molecular basis of several diseases. Several pharmaceutical agents and environmental toxins are also known to disrupt or inhibit aldehyde dehydrogenase function. (PMID: 17379813, 14697885, 11164826). 3,4-dihydroxymandelaldehyde, also known as alpha,3,4-trihydroxybenzeneacetaldehyde or dhmal, is a member of the class of compounds known as phenylacetaldehydes. Phenylacetaldehydes are compounds containing a phenylacetaldehyde moiety, which consists of a phenyl group substituted at the second position by an acetalydehyde. 3,4-dihydroxymandelaldehyde is soluble (in water) and a very weakly acidic compound (based on its pKa). 3,4-dihydroxymandelaldehyde can be found in a number of food items such as canola, lentils, grass pea, and moth bean, which makes 3,4-dihydroxymandelaldehyde a potential biomarker for the consumption of these food products. In humans, 3,4-dihydroxymandelaldehyde is involved in a couple of metabolic pathways, which include disulfiram action pathway and tyrosine metabolism. 3,4-dihydroxymandelaldehyde is also involved in several metabolic disorders, some of which include dopamine beta-hydroxylase deficiency, alkaptonuria, hawkinsinuria, and tyrosinemia, transient, of the newborn.
