5-(2-Hydroxyethyl)-4-methylthiazole
5-(2-hydroxyethyl)-4-methylthiazole, also known as 4-methyl-5-thiazolethanol or 4-methyl-5-(β-hydroxyethyl)thiazole, is a member of the class of compounds known as 4,5-disubstituted thiazoles. 4,5-disubstituted thiazoles are compounds containing a thiazole ring substituted at positions 4 and 5 only. 5-(2-hydroxyethyl)-4-methylthiazole is slightly soluble (in water) and an extremely weak acidic compound (based on its pKa). 5-(2-hydroxyethyl)-4-methylthiazole is a cooked beef juice, fatty, and sulfur tasting compound and can be found in a number of food items such as nuts, cereals and cereal products, alcoholic beverages, and mushrooms, which makes 5-(2-hydroxyethyl)-4-methylthiazole a potential biomarker for the consumption of these food products. 5-(2-hydroxyethyl)-4-methylthiazole can be found primarily in feces. 5-(2-hydroxyethyl)-4-methylthiazole exists in all living species, ranging from bacteria to humans. 5-(2-Hydroxyethyl)-4-methylthiazole, also known as 4-methyl-5-(2-hydroxyethyl)-thiazole or 4-methyl-5-thiazolethanol, belongs to the class of organic compounds known as 4,5-disubstituted thiazoles. 4,5-disubstituted thiazoles are compounds containing a thiazole ring substituted at positions 4 and 5 only. 5-(2-Hydroxyethyl)-4-methylthiazole exists in all living species, ranging from bacteria to humans. 5-(2-Hydroxyethyl)-4-methylthiazole is a sulfur tasting compound. 5-(2-Hydroxyethyl)-4-methylthiazole has been detected, but not quantified, in several different foods, such as kohlrabis, red bell peppers, citrus, avocado, and black-eyed pea. This could make 5-(2-hydroxyethyl)-4-methylthiazole a potential biomarker for the consumption of these foods.

Vinylacetylglycine
Vinylacetylglycine is an acyl glycine. Acyl glycines are normally minor metabolites of fatty acids. However, the excretion of certain acyl glycines is increased in several inborn errors of metabolism. In certain cases the measurement of these metabolites in body fluids can be used to diagnose disorders associated with mitochondrial fatty acid beta-oxidation. Acyl glycines are produced through the action of glycine N-acyltransferase (EC 2.3.1.13) which is an enzyme that catalyzes the chemical reaction:. acyl-CoA + glycine < -- > CoA + N-acylglycine. Vinylacetylglycine is a human metabolite that had been identified in a GC/MS urine screen. Increased amounts of this metabolite in the urine has been linked to a metabolomic disorder termed Isovaleric acidemia. (Gas-Chromatographic Method of Analysis for Urinary Organic Acids. I. Retention indices of 155 metaboically Important Compounds; Kay Tanaka, David G. Hine, Agnes West-Dull, and Theodore B. Lynn.). Vinylacetylglycine is an acyl glycine.

Trimethadione
Trimethadione is only found in individuals that have used or taken this drug. It is an anticonvulsant effective in absence seizures, but generally reserved for refractory cases because of its toxicity. (From AMA Drug Evaluations Annual, 1994, p378)Trimethadione reduces T-type calcium currents in thalamic neurons, including thalamic relay neurons. It does so via the inhibition of voltage dependent T-type calcium channels. This raises the threshold for repetitive activity in the thalamus, and inhibits corticothalamic transmission. Thus, the abnormal thalamocortical rhythmicity, which is thought to underlie the 3-Hz spike-and-wave discharge seen on electroencephalogram(EEG) with absence seizures, is dampened.

6-oxopiperidine-2-carboxylate
6-Oxopiperidine-2-carboxylic acid, also known as 6-Oxo-pipecolinic acid, or 6-Oxo-piperidine-2-carboxylic acid, is associated with penicillin V in the production on Penicillium chrysogenum fermentations. Analysis of a 13C NMR spectrum of a concentrated broth from Penicillium chrysogenum fermentation revealed the presence of penicillin V and 6-oxo-piperidine-2-carboxylic acid(1) as the principal constituents. The latter lactam, identical to an authentic sample prepared by the cyclization of alpha-aminoadipic acid was present to the extent of 28 mol\\% of penicillin V. The lactam isolated form the broth was nearly racemic, having a slight excess of the L-isomer. This isolation provides further evidence regarding the biosynthetic precursors of the hydrophobic penicillins. (PMID: 6788737
