Spermidine, also known as N-(3-aminopropyl)-1,4-butane-diamine or 1,5,10-triazadecane, is a member of the class of compounds known as dialkylamines. Dialkylamines are organic compounds containing a dialkylamine group, characterized by two alkyl groups bonded to the amino nitrogen. Spermidine is soluble (in water) and a very strong basic compound (based on its pKa). Spermidine can be found in radish, which makes spermidine a potential biomarker for the consumption of this food product. Spermidine can be found primarily in most biofluids, including urine, blood, saliva, and feces, as well as throughout most human tissues. Spermidine exists in all living organisms, ranging from bacteria to humans. In humans, spermidine is involved in a couple of metabolic pathways, which include methionine metabolism and spermidine and spermine biosynthesis. Spermidine is also involved in several metabolic disorders, some of which include homocystinuria-megaloblastic anemia due to defect in cobalamin metabolism, cblg complementation type, methionine adenosyltransferase deficiency, s-adenosylhomocysteine (SAH) hydrolase deficiency, and hypermethioninemia. Spermidine is a non-carcinogenic (not listed by IARC) potentially toxic compound. Spermidine is a polyamine compound (C 7H 19N 3) found in ribosomes and living tissues, and having various metabolic functions within organisms. It was originally isolated from semen . As a uremic toxin, this compound can cause uremic syndrome. Uremic syndrome may affect any part of the body and can cause nausea, vomiting, loss of appetite, and weight loss. It can also cause changes in mental status, such as confusion, reduced awareness, agitation, psychosis, seizures, and coma. Abnormal bleeding, such as bleeding spontaneously or profusely from a very minor injury can also occur. Heart problems, such as an irregular heartbeat, inflammation in the sac that surrounds the heart (pericarditis), and increased pressure on the heart can be seen in patients with uremic syndrome. Shortness of breath from fluid buildup in the space between the lungs and the chest wall (pleural effusion) can also be present (T3DB).
