putrescine

 [pu-tres´in]
a polyamine first found in decaying meat; small quantities occur in most cells.

pu·tres·cine

(pyū-tres'ēn),
1,4-Diaminobutane; a poisonous polyamine formed from the amino acid arginine during putrefaction; found in urine and feces; in certain cells, putrescine is a precursor to γ-aminobutyrate.

putrescine

/pu·tres·cine/ (pu-tres´in) a polyamine precursor of spermidine, first found in decaying meat but now known to occur in almost all tissues and in some bacterial cultures.

putrescine

(pyo͞o-trĕs′ēn)
n.
A colorless, foul-smelling polyamine, C4H12N2, produced in decaying animal tissue by the decarboxylation of ornithine.

putrescine

[pyo̅o̅′tresēn]
a foul-smelling toxic ptomaine produced by the decomposition of the amino acid ornithine during the decay of animal tissues, bacillus cultures, and fecal bacteria.
