Putresina
senyawa kimia
Putresina, atau tetramethylenediamine, adalah suatu senyawa kimia organik NH2(CH2)4NH2 (1,4-diaminobutane or butanediamine) yang berbau busuk[1] yang berhuungan dengan kadaverina; keduanya dihasilkan melalui pemecahan asam amino dalam organisme hidup dan mati dan keduanya merupakan racun dalam dosis besar.[2][3] The two compounds are largely responsible for the foul odor of putrefying flesh, but also contribute to the odor of such processes as bad breath and bacterial vaginosis.[4] They are also found in semen and some microalgae, together with related molecules like spermine and spermidine.

Ornithine is converted by bowel bacteria into a toxic substance called putrescine, which in turn degrades into polyamines, such as spermadine, spermine, and cadaverine (literally meaning "the essence of dead cadavers").
