Identification
Name: p-Cresol
Description:p-Cresol, also known as 4-methylphenol or 4-hydroxytoluene, is a positional isomer of cresol. The other two isomers are m-cresol and o-cresol. (Wikipedia) p-Cresol is one of the metabolites of the amino acid tyrosine, and to a certain extent also of phenylalanine, which are converted to 4-hydroxyphenylacetic acid by intestinal bacteria, before being decarboxylated to p-cresol (putrefaction). The main contributing bacteria are aerobes (mainly enterobacteria), but to a certain extent also anaerobes play a role (mainly Clostridium perfringens). p-Cresol has been reported to affect several biochemical, biological and physiological functions: for example, it alters cell membrane permeability in bacteria. (HMDB, PMID 10570076) In Pseudomonas aeruginosa, p-Cresol can be produced as a by-product of thiazole biosynthesis. (EcoCyc)
