Putrescine is an end product of fatty acid metabolism in dead tissues. It is a volatile diamine with pungent odour. It is synthesized by the decarboxylation of ornithine in the presence of enzyme, ornithine decarboxylase. Molecular docking studies reveal the binding of putrescine to human receptors called the trace amine-associated receptors (TAAR6 and TAAR8), present in olfactory epithelium.
腐胺是死亡组织中脂肪酸代谢的最终产物。 它是一种具有刺激性气味的挥发性二胺。 它是在鸟氨酸脱羧酶存在的情况下，通过鸟氨酸的脱羧作用合成的。 分子对接研究揭示了腐胺与嗅觉上皮细胞中存在的称为痕量胺相关受体（TAAR6和TAAR8）的人类受体结合。
Putrescine dihydrochloride has been used as medium component in F-12 + GlutaMax medium for mice ganglia culture, retinal ganglion cell culture and in HCT116 colon carcinoma cells for ornithine decarboxylase (ODC) assay.
盐酸腐胺被用作F-12 + GlutaMax培养基的成分，用于小鼠神经节培养，视网膜神经节细胞培养和HCT116结肠癌细胞中用于鸟氨酸脱羧酶（ODC）分析。
Putrescine is regarded as a marker of stress in plants. External supplementation of putrescine helps wheat plants to overcome drought stress. It is crucial for cell proliferation in animals and modulates abscisic acid (ABA) levels during cold stress in Arabidopsis plants. It serves as an attractant for predators.
