L-2,3-Dihydrodipicolinate
L-2,3-Dihydrodipicolinate is involved in the lysine biosynthesis I pathway. L-2,3-Dihydrodipicolinate is produced from a reaction between pyruvate and L-aspartate-semialdehyde, with water as a byproduct. The reaction is catalyzed by dihydrodipicolinate synthase. L-2,3-dihydrodipicolinate reacts with NAD(P)H and H+ to produce tetrahydrodipicolinate and NAD(P)+. The reaction is catalyzed by dihydrodipicolinate reductase.

4-Methyl-5-nitrocatechol
A nitrotoluene that is 2-nitrotoluene carrying two hydroxy substituents at positions 4 and 5.
2-Furoylglycine
2-Furoylglycine 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. Dietary studies show that 2-Furoylglycine precursors are of exogenous origin. Most probably from furan derivatives found in food prepared by strong heating. This may explain the absence of 2-furoylglycine in urine of breastfed children (PMID 4630229). 2-Furoylglycine is also a microbial metabolite. 2-Furoylglycine is an acyl glycine.

Phosphodimethylethanolamine
Phosphomonomethylethanolamine, phosphodimethylethanolamine and phosphocholine were weak competitive inhibitors of the cytidylyltransferase catalyzed reaction when phosphoethanolamine was used as a substrate, with Ki values of 7.0, 6.8 and 52.9 mM, respectively. (PMID: 8130268) Unlike the plant and Plasmodium PEAMT, which catalyze all three methylations in the pathway, PMT-2 catalyzes only the last two steps in the pathway, i.e., the methylation of phosphomonomethylethanolamine (P-MME) to phosphodimethylethanolamine (P-DME) and of P-DME to phosphocholine.

(S)-2,3,4,5-tetrahydrodipicolinate
(s)-2,3,4,5-tetrahydrodipicolinate belongs to alpha amino acids and derivatives class of compounds. Those are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon), or a derivative thereof (s)-2,3,4,5-tetrahydrodipicolinate is slightly soluble (in water) and a weakly acidic compound (based on its pKa). (s)-2,3,4,5-tetrahydrodipicolinate can be found in a number of food items such as wasabi, java plum, tarragon, and scarlet bean, which makes (s)-2,3,4,5-tetrahydrodipicolinate a potential biomarker for the consumption of these food products (s)-2,3,4,5-tetrahydrodipicolinate may be a unique E.coli metabolite.
