1,5-Diaminopentane is a diamine that is produced from the amino acid lysine by decarboxylation as a result of microbial decomposition of protein . Hence it is called a biogenic amine . As a putrefaction base, it is part of the ptomaine (also called corpse poison ) and also contributes to the odor of decay . In addition to diaminobutane ( putrescine ), it also occurs in human seminal fluid , where it serves non-specific defense mechanisms.
The diamine was first isolated by Ludwig Brieger in 1885 . A sample of Brieger's first cadaverine is kept in the collections of the Deutsches Museum .
1,5-diaminopentane is the biosynthetic precursor of some quinolizidine alkaloids , lycopodium alkaloids and piperidine alkaloids .
