PTOMAINES

From Big Medical Encyclopedia

PTOMAINES (synonym ptomatina) — the outdated term used in biological literature for designation of group of nitrogen-containing chemical compounds, the so-called ptomaine which is formed as a result of ichorization of proteins of corpses and protein-rich products: meat, fish, yeast and so forth. Referred to P. various connections, hl. obr. biogenic amines — putrestsin, pentamethylenediamine (see), agmatin (alpha aminobutylguanidine), neurine (see), and also products of enzymatic decarboxylation of some amino acids which are a part of natural proteins — a histamine, tyramine, a triptamin. Toxicity of ptomaine is caused not by P. as mistakenly believed earlier, and generally bacterial toxins which are formed as a result of life activity of the microorganisms participating in ichorization of proteic matters. Toxicity of the majority of the connections combined before under the name «ptomaines» is small.
