Basic introduction of spermidine

Spermine, also known as spermidine trihydrochloride, is a type of polyamine. Widely distributed in living organisms, it is biosynthesized from putrescine (butanediamine) and adenosylmethionine. Spermidine can inhibit neuronal synthase, bind and precipitate DNA; It can also be used to purify DNA binding proteins and stimulate T4 polynucleotide kinase activity. On September 1, 2013, scientists from Germany and Austria collaborated to study that spermidine may prevent the onset of Alzheimer's disease in the elderly.
