Plasma concentrations of free and conjugated phenylacetic acid, the major metabolite of phenylethylamine, were higher in ten prisoners serving long terms of imprisonment for violent crimes than in pair-matched non-violent control prisoners. Since amphetamine, a compound closely related to phenylethylamine, can reduce aggressiveness in some violent subjects, the increase in phenylethylamine production may be an attempt to compensate for the unknown derangement of function responsible for increased aggression.
苯乙胺的主要代谢产物——游离型和结合型苯乙酸的血浆浓度，在十名因暴力犯罪而长期服刑的囚犯中，高于配对的非暴力对照囚犯。由于与苯乙胺密切相关的化合物安非他命可降低一些暴力受试者的攻击性，苯乙胺生成增加可能是一种试图补偿导致攻击性增加的未知功能紊乱的尝试。
