Pregnanediol (5Beta-Pregnane-3Alpha,20alpha-Diol) is an inactive metabolite of PROGESTERONE by reduction at C5, C3, and C20 position. Pregnanediol(5Beta-Pregnane-3Alpha,20alpha-Diol) has two hydroxyl groups, at 3-alpha and 20-alpha. It is detectable in URINE after OVULATION and is found in great quantities in the pregnancy urine.

3,4-Dimethoxybenzyl alcohol is a secondary metabolite of lignin-degrading fungi and is commonly used as a non-phenolic substrate to measure ligninolytic activity.Veratryl alcohol protects lignin peroxidase (LiP) from inactivation by H2O2 and prevents accumulation of LiP III compounds[3].

4-Aminohippuric Acid is the glycine amide of 4-aminobenzoic acid. Its sodium salt is used as a diagnostic aid to measure effective renal plasma flow (ERPF) and excretory capacity.

2,4-Dihydroxypyridine is a pyridine derivative that acts as a chelating agent binding to metal ions and forming complexes. It is used as a reagent for determining the concentration of various ions, such as calcium, magnesium and phosphate. It is also used to measure the rate of enzyme-catalyzed reactions. It is also used for the detection and quantification of proteins, carbohydrates and other biomolecules.

2-(Methylamino)benzoic acid, the primary metabolite of methyl-N-methylanthranilates (MMA), results from the conversion of the ester group in MMA. This compound, extractable from citrus fruits and possessing potential analgesic activity, was utilized to measure MMA metabolic levels in rat liver [1].

N-Carbamoyl-L-aspartic acid, an intermediate in pyrimidine metabolism, can be utilized to measure the enzyme activity of dihydroorotase (DHOse) [1] [2].
