Cadaverine
Cadaverine (1,5-diaminopentane) is a biogenic amine produced by bacterial lysine decarboxylase — primarily by Enterobacteriaceae, Fusobacterium, and Clostridium — during proteolytic fermentation of undigested protein in the distal colon. It is a product of putrefaction …

p-Cresol
A microbial metabolite produced by gut bacteria through tyrosine fermentation that has emerged as one of the most consistent biomarkers linking gut dysbiosis to neurological and renal disease. p-Cresol (4-methylphenol) is a simple aromatic compound, but its effects are …

Propionic Acid
A three-carbon short-chain fatty acid (SCFA) produced primarily by Bacteroidetes and certain Firmicutes through anaerobic fermentation of dietary substrates. At physiological concentrations in healthy gut microbiomes, propionic acid (PPA) is a normal fermentation produc…

Short-Chain Fatty Acids (SCFAs)
The most extensively referenced missing concept in this wiki. SCFAs -- acetate (C2), propionate (C3), and butyrate (C4) -- are the primary metabolic products of anaerobic bacterial fermentation of dietary fiber in the colon. They serve as the critical molecular link bet…

Uremic Toxins
Uremic toxins are metabolic waste products that accumulate in the blood when kidney function declines. A striking proportion of the most clinically significant uremic toxins are produced not by human metabolism but by the gut microbiome -- making the gut-kidney axis a c…
