p-Cresol is produced by bacterial fermentation of protein in the human large intestine. It is excreted in feces and urine, [7] and is a component of human sweat that attracts female mosquitoes. [8] [9] p-Cresol is a constituent of tobacco smoke. [10]

P-cresol is a cresol that consists of toluene substituted by a hydroxy group at position 4. It is a metabolite of aromatic amino acid metabolism produced by intestinal microflora in humans and animals. It has a role as a uremic toxin, a human metabolite and an Escherichia coli metabolite.

There are three forms of cresol: ortho-cresol (o-cresol), meta-cresol (m-cresol), and para-cresol (p-cresol). These forms occur separately or as a mixture, which can also be called cresol or more specifically, tricresol .

Three types (or isomers) of cresols exist: ortho-cresol, meta-cresol, and para-cresol; abbreviated as o-cresol, m-cresol, and p-cresol. Pure cresols are solid, while mixtures tend to be liquid. Cresols have a medicinal smell.

In anaerobic groundwater samples and groundwater samples with aquifer materials, cresol isomers display the same pattern of degradation p-cresol > m-cresol > o-cresol, where p-cresol is the most readily biodegradable of the three isomers, seen in …

There are three forms of cresols that differ slightly in their chemical structure: ortho-cresol (o-cresol), meta-cresol (m-cresol, and para-cresol (p-cresol). These forms occur separately or as a mixture.

p-Cresol exposure resulted in concentration- and time-dependent changes in DCF (EC 50 = 0.64 ± 0.37 mM at 24 h of exposure) formation, GSH (EC 50 = 1.00 ± 0.07 mM) concentration, and LDH (EC 50 = 0.85 ± 0.14 mM) release at toxicologically relevant conditions.
